Custom hardware designs significantly accelerate the execution of these algorithms. In this article, we demonstrate a high-performance B&B implementation on FPGAs. First, we identify general elements of B&B algorithms and describe their implementation as a finite state machine. Then, we introduce workers that autonomously cooperate using work stealing to allow parallel execution and full utilization of the target FPGA. Finally, we explore advantages of instance-specific designs that target a specific problem instance to improve performance.\r\n\r\nWe evaluate our concepts by applying them to a branch and bound problem, the reconstruction of corrupted AES keys obtained from cold-boot attacks. The evaluation shows that our work stealing approach is scalable with the available resources and provides speedups proportional to the number of workers. Instance-specific designs allow us to achieve an overall speedup of 47 × compared to the fastest implementation of AES key reconstruction so far. Finally, we demonstrate how instance-specific designs can be generated just-in-time such that the provided speedups outweigh the additional time required for design synthesis."}],"user_id":"15278","ddc":["000"]},{"language":[{"iso":"eng"}],"date_updated":"2023-09-26T13:24:38Z","doi":"10.23919/FPL.2017.8056844","department":[{"_id":"27"},{"_id":"518"},{"_id":"61"}],"project":[{"_id":"1","grant_number":"160364472","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C2","grant_number":"160364472","_id":"14"},{"name":"HighPerMeshes","grant_number":"01|H16005A","_id":"33"},{"grant_number":"PL 595/2-1 / 320898746","name":"Performance and Efficiency in HPC with Custom Computing","_id":"32"},{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"title":"Flexible FPGA design for FDTD using OpenCL","type":"conference","citation":{"ieee":"T.

In this work, we evaluate the extent of this promise. To this end, we present a parameterized FDTD implementation for photonic microcavity simulations. Our design can trade-off different forms of parallelism and works for two independent OpenCL-based FPGA design flows. Hence, we can target FPGAs from different vendors and different FPGA families. We describe how we used pre-processor macros to achieve this flexibility and to work around different shortcomings of the current tools. Choosing the right design configurations, we are able to present two extremely competitive solutions for very different FPGA targets, reaching up to 172 GFLOPS sustained performance. With the portability and flexibility demonstrated, code developers not only avoid vendor lock-in, but can even make best use of real trade-offs between different architectures."}],"ddc":["000"],"user_id":"15278"},{"volume":898,"status":"public","date_created":"2018-03-22T10:51:20Z","publisher":"IOP Publishing","quality_controlled":"1","author":[{"last_name":"Schumacher","full_name":"Schumacher, Jörn","first_name":"Jörn"},{"last_name":"Plessl","id":"16153","first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982"},{"first_name":"Wainer","full_name":"Vandelli, Wainer","last_name":"Vandelli"}],"department":[{"_id":"27"},{"_id":"518"}],"publication":"Journal of Physics: Conference Series","title":"High-Throughput and Low-Latency Network Communication with NetIO","user_id":"15278","citation":{"short":"J.

To move one step further from the state-of-the-art multicore plus accelerator approaches, we present in this paper our innovative SAVEHSA architecture. It comprises of a heterogeneous hardware platform with three different high-end accelerators attached over PCIe (GPGPU, FPGA and Intel MIC). Such systems can process parallel workloads very efficiently whilst being more energy efficient than regular CPU systems. To leverage the heterogeneity, the workload has to be distributed among the computing units in a way that each unit is well-suited for the assigned task and executable code must be available. To tackle this problem we present two software components; the first can perform resource allocation at runtime while respecting system and application goals (in terms of throughput, energy, latency, etc.) and the second is able to analyze an application and generate executable code for an accelerator at runtime. We demonstrate the first proof-of-concept implementation of our framework on the heterogeneous platform, discuss different runtime policies and measure the introduced overheads.","lang":"eng"}],"user_id":"15278","ddc":["040"],"citation":{"bibtex":"@inproceedings{Riebler_Vaz_Plessl_Trainiti_Durelli_Del Sozzo_Santambrogio_Bolchini_2016, title={Using Just-in-Time Code Generation for Transparent Resource Management in Heterogeneous Systems}, DOI={10.1109/RTSI.2016.7740545}, booktitle={Proceedings of International Forum on Research and Technologies for Society and Industry (RTSI)}, publisher={IEEE}, author={Riebler, Heinrich and Vaz, Gavin Francis and Plessl, Christian and Trainiti, Ettore M.

Such systems need to adapt task scheduling and mapping to optimise for performance and energy under varying workloads and, increasingly important, for thermal and fault management and are thus relevant targets for self-aware computing. In this chapter, we take up the generic reference architecture for designing self-aware and self-expressive computing systems and refine it for heterogeneous multi-cores. We present ReconOS, an architecture, programming model and execution environment for heterogeneous multi-cores, and show how the components of the reference architecture can be implemented on top of ReconOS. In particular, the unique feature of dynamic partial reconfiguration supports self-expression through starting and terminating reconfigurable hardware cores. We detail a case study that runs two applications on an architecture with one CPU and 12 reconfigurable hardware cores and present self-expression strategies for adapting under performance, temperature and even conflicting constraints. The case study demonstrates that the reference architecture as a model for self-aware computing is highly useful as it allows us to structure and simplify the design process, which will be essential for designing complex future compute nodes. Furthermore, ReconOS is used as a base technology for flexible protocol stacks in Chapter 10, an approach for self-aware computing at the networking level.","lang":"eng"}],"has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:41:22Z","file":[{"file_id":"5613","creator":"aloesch","file_size":833054,"relation":"main_file","success":1,"content_type":"application/pdf","date_updated":"2018-11-14T13:20:32Z","date_created":"2018-11-14T13:20:32Z","file_name":"chapter8.pdf","access_level":"closed"}],"quality_controlled":"1","author":[{"last_name":"Agne","full_name":"Agne, Andreas","first_name":"Andreas"},{"first_name":"Markus","full_name":"Happe, Markus","last_name":"Happe"},{"id":"43646","last_name":"Lösch","full_name":"Lösch, Achim","first_name":"Achim"},{"id":"16153","last_name":"Plessl","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","first_name":"Christian"},{"first_name":"Marco","full_name":"Platzner, Marco","last_name":"Platzner","id":"398"}],"publisher":"Springer International Publishing","file_date_updated":"2018-11-14T13:20:32Z","publication":"Self-aware Computing Systems","doi":"10.1007/978-3-319-39675-0_8","date_updated":"2023-09-26T13:27:44Z","language":[{"iso":"eng"}],"series_title":"Natural Computing Series (NCS)","title":"Self-aware Compute Nodes","place":"Cham","project":[{"_id":"1","grant_number":"160364472","name":"SFB 901"},{"_id":"14","grant_number":"160364472","name":"SFB 901 - Subprojekt C2"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"Engineering Proprioception in Computing Systems","grant_number":"257906","_id":"31"}],"department":[{"_id":"518"},{"_id":"27"},{"_id":"78"}]},{"_id":"165","intvolume":" 55","citation":{"chicago":"Vaz, Gavin Francis, Heinrich Riebler, Tobias Kenter, and Christian Plessl. “Potential and Methods for Embedding Dynamic Offloading Decisions into Application Code.” Computers and Electrical Engineering 55 (2016): 91–111. https://doi.org/10.1016/j.compeleceng.2016.04.021.","apa":"Vaz, G.

However, to achieve speedups, the number of loop it- erations (trip count) needs to be sufficiently large to amortize offloading overheads. Trip counts are frequently not known at compile time, but only at runtime just before entering a loop. Therefore, we propose to generate code for both the CPU and the coprocessor, and defer the offloading decision to the application runtime. We demonstrate how a toolflow, based on the LLVM compiler framework, can automatically embed dynamic offloading de- cisions into the application code. We perform in-depth static and dynamic analysis of pop- ular benchmarks, which confirm the general potential of such an approach. We also pro- pose to optimize the offloading process by decoupling the runtime decision from the loop execution (decision slack). The feasibility of our approach is demonstrated by a toolflow that automatically identifies suitable data-parallel loops and generates code for the FPGA coprocessor of a Convey HC-1. We evaluate the integrated toolflow with representative loops executed for different input data sizes.","lang":"eng"}],"user_id":"15278","ddc":["040"],"file":[{"file_size":3037854,"creator":"florida","file_id":"1544","content_type":"application/pdf","date_updated":"2018-03-21T12:45:47Z","relation":"main_file","success":1,"date_created":"2018-03-21T12:45:47Z","file_name":"165-1-s2.0-S0045790616301021-main.pdf","access_level":"closed"}],"author":[{"id":"30332","last_name":"Vaz","full_name":"Vaz, Gavin Francis","first_name":"Gavin Francis"},{"id":"8961","last_name":"Riebler","full_name":"Riebler, Heinrich","first_name":"Heinrich"},{"full_name":"Kenter, Tobias","first_name":"Tobias","id":"3145","last_name":"Kenter"},{"last_name":"Plessl","id":"16153","first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982"}],"quality_controlled":"1","publisher":"Elsevier","file_date_updated":"2018-03-21T12:45:47Z","publication":"Computers and Electrical Engineering","has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:41:24Z","volume":55,"date_updated":"2023-09-26T13:26:38Z","doi":"10.1016/j.compeleceng.2016.04.021","language":[{"iso":"eng"}],"title":"Potential and Methods for Embedding Dynamic Offloading Decisions into Application Code","department":[{"_id":"27"},{"_id":"518"}],"project":[{"name":"SFB 901","grant_number":"160364472","_id":"1"},{"_id":"14","grant_number":"160364472","name":"SFB 901 - Subprojekt C2"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","grant_number":"610996","_id":"34"}],"publication_identifier":{"issn":["0045-7906"]}},{"_id":"168","type":"conference","citation":{"ieee":"A.

Approaches for managing and scheduling tasks to heterogeneous resources are still subject to research. Although queuing systems have recently been extended to support accelerator resources, a general solution that manages heterogeneous resources at the operating system- level to exploit a global view of the system state is still missing.In this paper we present a user space scheduler that enables task scheduling and migration on heterogeneous processing resources in Linux. Using run queues for available resources we perform scheduling decisions based on the system state and on task characterization from earlier measurements. With a pro- gramming pattern that supports the integration of checkpoints into applications, we preempt tasks and migrate them between three very different compute resources. Considering static and dynamic workload scenarios, we show that this approach can gain up to 17% performance, on average 7%, by effectively avoiding idle resources. We demonstrate that a work-conserving strategy without migration is no suitable alternative.","lang":"eng"}],"has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:41:24Z","publisher":"EDA Consortium / IEEE","author":[{"first_name":"Achim","full_name":"Lösch, Achim","last_name":"Lösch","id":"43646"},{"full_name":"Beisel, Tobias","first_name":"Tobias","last_name":"Beisel"},{"id":"3145","last_name":"Kenter","full_name":"Kenter, Tobias","first_name":"Tobias"},{"last_name":"Plessl","id":"16153","first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982"},{"full_name":"Platzner, Marco","first_name":"Marco","id":"398","last_name":"Platzner"}],"quality_controlled":"1","publication":"Proceedings of the 2016 Design, Automation & Test in Europe Conference & Exhibition (DATE)","file_date_updated":"2018-03-21T12:41:55Z","file":[{"access_level":"closed","date_created":"2018-03-21T12:41:55Z","file_name":"168-07459438.pdf","content_type":"application/pdf","date_updated":"2018-03-21T12:41:55Z","success":1,"relation":"main_file","file_size":261356,"file_id":"1541","creator":"florida"}],"date_updated":"2023-09-26T13:27:00Z","language":[{"iso":"eng"}],"title":"Performance-centric scheduling with task migration for a heterogeneous compute node in the data center","project":[{"_id":"1","grant_number":"160364472","name":"SFB 901"},{"_id":"14","grant_number":"160364472","name":"SFB 901 - Subprojekt C2"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"30","grant_number":"01|H11004A","name":"Enabling Heterogeneous Hardware Acceleration using Novel Programming and Scheduling Models"}],"department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}]},{"language":[{"iso":"eng"}],"type":"conference","citation":{"bibtex":"@inproceedings{Kenter_Vaz_Riebler_Plessl_2016, title={Opportunities for deferring application partitioning and accelerator synthesis to runtime (extended abstract)}, booktitle={Workshop on Reconfigurable Computing (WRC)}, author={Kenter, Tobias and Vaz, Gavin Francis and Riebler, Heinrich and Plessl, Christian}, year={2016} }","mla":"Kenter, Tobias, et al. “Opportunities for Deferring Application Partitioning and Accelerator Synthesis to Runtime (Extended Abstract).” Workshop on Reconfigurable Computing (WRC), 2016.","chicago":"Kenter, Tobias, Gavin Francis Vaz, Heinrich Riebler, and Christian Plessl. “Opportunities for Deferring Application Partitioning and Accelerator Synthesis to Runtime (Extended Abstract).” In Workshop on Reconfigurable Computing (WRC), 2016.","apa":"Kenter, T., Vaz, G.

At the same time, following classic methods to increase speed and reduce energy consumption of these devices becomes increasingly difficult, bringing alternative methods into focus. One of these methods is approximate computing which utilizes the fact that small errors in computations are acceptable in many applications in order to allow acceleration of these computations or to increase energy efficiency. This thesis develops elements of a workflow that can be followed to apply approximate computing to existing applications. It proposes a novel heuristic approach to the localization of code paths that are suitable to approximate computing based on findings in recent research. Additionally, an approach to identification of approximable instructions within these code paths is proposed and used to implement simulation of approximation. The parts of the workflow are implemented with the goal to lay the foundation for a partly automated toolflow. Evaluation of the developed techniques shows that the proposed methods can help providing a convenient workflow, facilitating the first steps into the application of approximate computing.","lang":"eng"}],"place":"Paderborn","date_created":"2018-03-26T15:24:10Z","status":"public","department":[{"_id":"27"},{"_id":"518"}],"publisher":"Paderborn University","author":[{"first_name":"Michael","orcid":"0000-0002-5708-7632","full_name":"Lass, Michael","last_name":"Lass","id":"24135"}]},{"year":"2015","type":"conference","citation":{"ieee":"T.

In this work, we compare the resulting performance of two design concepts that in different ways promise such increased productivity. As common starting point, we employ a kernel-centric design approach, where computational hotspots in an application are identified and individually accelerated on FPGA. By means of a complex stereo matching application, we evaluate two fundamentally different design philosophies and approaches for implementing the required kernels on FPGAs. In the first implementation approach, we designed individually specialized data flow kernels in a spatial programming language for a Maxeler FPGA platform; in the alternative design approach, we target a vector coprocessor with large vector lengths, which is implemented as a form of programmable overlay on the application FPGAs of a Convey HC-1. We assess both approaches in terms of overall system performance, raw kernel performance, and performance relative to invested resources. After compensating for the effects of the underlying hardware platforms, the specialized dataflow kernels on the Maxeler platform are around 3x faster than kernels executing on the Convey vector coprocessor. In our concrete scenario, due to trade-offs between reconfiguration overheads and exposed parallelism, the advantage of specialized dataflow kernels is reduced to around 2.5x.","lang":"eng"}],"user_id":"15278","ddc":["040"],"file":[{"file_name":"296-859425.pdf","date_created":"2018-03-20T07:47:56Z","access_level":"closed","file_size":2993898,"creator":"florida","file_id":"1444","content_type":"application/pdf","date_updated":"2018-03-20T07:47:56Z","success":1,"relation":"main_file"}],"publisher":"Hindawi","author":[{"id":"3145","last_name":"Kenter","full_name":"Kenter, Tobias","first_name":"Tobias"},{"last_name":"Schmitz","full_name":"Schmitz, Henning","first_name":"Henning"},{"id":"16153","last_name":"Plessl","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","first_name":"Christian"}],"quality_controlled":"1","publication":"International Journal of Reconfigurable Computing (IJRC)","file_date_updated":"2018-03-20T07:47:56Z","has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:41:49Z","volume":2015,"intvolume":" 2015","_id":"296","article_number":"859425","year":"2015","type":"journal_article","citation":{"short":"T.

Our work is based on Binary Acceleration At Runtime (BAAR), our previously introduced binary acceleration mechanism that uses the LLVM Compiler Infrastructure. BAAR is designed as a client-server architecture. The client runs the program to be accelerated in an environment, which allows program analysis and profiling and identifies and extracts suitable program parts to be offloaded. The server compiles and optimizes these offloaded program parts for the accelerator and offers access to these functions to the client with a remote procedure call (RPC) interface. Our previous work proved the feasibility of our approach, but also showed that communication time and overheads limit the granularity of functions that can be meaningfully offloaded. In this work, we motivate the importance of a lightweight, high-performance communication between server and client and present a communication mechanism based on the Message Passing Interface (MPI). We evaluate our approach by using an Intel Xeon Phi 5110P as the acceleration target and show that the communication overhead can be reduced from 40% to 10%, thus enabling even small hotspots to benefit from offloading to an accelerator.","lang":"eng"}],"status":"public","has_accepted_license":"1","date_created":"2017-10-17T12:41:38Z","quality_controlled":"1","publisher":"EDA Consortium / IEEE","author":[{"last_name":"Damschen","first_name":"Marvin","full_name":"Damschen, Marvin"},{"id":"8961","last_name":"Riebler","full_name":"Riebler, Heinrich","first_name":"Heinrich"},{"last_name":"Vaz","id":"30332","first_name":"Gavin Francis","full_name":"Vaz, Gavin Francis"},{"first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","last_name":"Plessl","id":"16153"}],"publication":"Proceedings of the 2015 Conference on Design, Automation and Test in Europe (DATE)","file_date_updated":"2018-03-21T10:29:49Z","file":[{"access_level":"closed","file_name":"238-plessl15_date.pdf","date_created":"2018-03-21T10:29:49Z","relation":"main_file","success":1,"date_updated":"2018-03-21T10:29:49Z","content_type":"application/pdf","creator":"florida","file_id":"1500","file_size":380552}],"_id":"238","citation":{"ieee":"M.

A new class of devices will be needed to interface many GBT links to the rest of the trigger, data-acquisition and detector control systems. In this paper FELIX (Front End LInk eXchange) is presented, a PC-based device to route data from and to multiple GBT links via a high-performance general purpose network capable of a total throughput up to O(20 Tbps).

Diese Grenze hat in den letzten Jahrzehnten nicht nur die Entwicklung von Computersystemen bestimmt, sondern auch die Strukturierung der Ausbildung in den Computerwissenschaften beeinflusst und sogar zur Entstehung von neuen Forschungsrichtungen gef{\\\"u}hrt. In diesem Beitrag besch{\\\"a}ftigen wir uns mit Verschiebungen an der Grenze zwischen Hardware und Software und diskutieren insgesamt drei qualitativ unterschiedliche Formen solcher Verschiebungen. Wir beginnen mit der Entwicklung von Computersystemen im letzten Jahrhundert und der Entstehung dieser Grenze, die Hardware und Software erst als eigenst{\\\"a}ndige Produkte differenziert. Dann widmen wir uns der Frage, welche Funktionen in einem Computersystem besser in Hardware und welche besser in Software realisiert werden sollten, eine Fragestellung die zu Beginn der 90er-Jahre zur Bildung einer eigenen Forschungsrichtung, dem sogenannten Hardware/Software Co-design, gef{\\\"u}hrt hat. Im Hardware/Software Co-design findet eine Verschiebung von Funktionen an der Grenze zwischen Hardware und Software w{\\\"a}hrend der Entwicklung eines Produktes statt, um Produkteigenschaften zu optimieren. Im fertig entwickelten und eingesetzten Produkt hingegen k{\\\"o}nnen wir dann eine feste Grenze zwischen Hardware und Software beobachten. Im dritten Teil dieses Beitrags stellen wir mit selbst-adaptiven Systemen eine hochaktuelle Forschungsrichtung vor. In unserem Kontext bedeutet Selbstadaption, dass ein System Verschiebungen von Funktionen an der Grenze zwischen Hardware und Software autonom w{\\\"a}hrend der Betriebszeit vornimmt. Solche Systeme beruhen auf rekonfigurierbarer Hardware, einer relativ neuen Technologie mit der die Hardware eines Computers w{\\\"a}hrend der Laufzeit ver{\\\"a}ndert werden kann.

Most researchers rely on temperature simulations to evaluate their novel thermal management techniques. However, these temperature simulations require a high computational effort if a detailed thermal model is used and their accuracies are often unclear. In contrast to simulations, the use of synthetic heat sources allows for experimental evaluation of temperature management methods. In this paper we investigate the creation of significant rises in temperature on modern FPGAs to enable future evaluation of thermal management techniques based on experiments. To that end, we have developed seven different heat-generating cores that use different subsets of FPGA resources. Our experimental results show that, according to external temperature probes connected to the FPGA’s heat sink, we can increase the temperature by an average of 81 !C. This corresponds to an average increase of 156.3 !C as measured by the built-in thermal diodes of our Virtex-5 FPGAs in less than 30 min by only utilizing about 21 percent of the slices.","lang":"eng"}],"user_id":"15278","ddc":["040"],"file":[{"access_level":"closed","file_name":"363-plessl13_micpro.pdf","date_created":"2018-03-20T07:20:31Z","date_updated":"2018-03-20T07:20:31Z","content_type":"application/pdf","success":1,"relation":"main_file","file_size":1499996,"creator":"florida","file_id":"1408"}],"publisher":"Elsevier","author":[{"last_name":"Agne","first_name":"Andreas","full_name":"Agne, Andreas"},{"full_name":"Hangmann, Hendrik","first_name":"Hendrik","last_name":"Hangmann"},{"full_name":"Happe, Markus","first_name":"Markus","last_name":"Happe"},{"last_name":"Platzner","id":"398","first_name":"Marco","full_name":"Platzner, Marco"},{"first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","last_name":"Plessl","id":"16153"}],"quality_controlled":"1","file_date_updated":"2018-03-20T07:20:31Z","publication":"Microprocessors and Microsystems","status":"public","has_accepted_license":"1","date_created":"2017-10-17T12:42:02Z","volume":38,"date_updated":"2023-09-26T13:33:06Z","doi":"10.1016/j.micpro.2013.12.001","language":[{"iso":"eng"}],"title":"Seven Recipes for Setting Your FPGA on Fire – A Cookbook on Heat Generators","department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"project":[{"name":"SFB 901","grant_number":"160364472","_id":"1"},{"_id":"14","grant_number":"160364472","name":"SFB 901 - Subprojekt C2"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"31","grant_number":"257906","name":"Engineering Proprioception in Computing Systems"}]},{"type":"conference","citation":{"bibtex":"@inproceedings{Riebler_Kenter_Plessl_Sorge_2014, title={Reconstructing AES Key Schedules from Decayed Memory with FPGAs}, DOI={10.1109/FCCM.2014.67}, booktitle={Proceedings of Field-Programmable Custom Computing Machines (FCCM)}, publisher={IEEE}, author={Riebler, Heinrich and Kenter, Tobias and Plessl, Christian and Sorge, Christoph}, year={2014}, pages={222–229} }","mla":"Riebler, Heinrich, et al. “Reconstructing AES Key Schedules from Decayed Memory with FPGAs.” Proceedings of Field-Programmable Custom Computing Machines (FCCM), IEEE, 2014, pp. 222–29, doi:10.1109/FCCM.2014.67.","chicago":"Riebler, Heinrich, Tobias Kenter, Christian Plessl, and Christoph Sorge. “Reconstructing AES Key Schedules from Decayed Memory with FPGAs.” In Proceedings of Field-Programmable Custom Computing Machines (FCCM), 222–29.

This operation is a crucial and time consuming operation when trying to break encryption systems with cold-boot attacks. In software, the reconstruction of the AES master key can be performed using a recursive, branch-and-bound tree-search algorithm that exploits redundancies in the key schedule for constraining the search space. In this work, we investigate how this branch-and-bound algorithm can be accelerated with FPGAs. We translated the recursive search procedure to a state machine with an explicit stack for each recursion level and create optimized datapaths to accelerate in particular the processing of the most frequently accessed tree levels. We support two different decay models, of which especially the more realistic non-idealized asymmetric decay model causes very high runtimes in software. Our implementation on a Maxeler dataflow computing system outperforms a software implementation for this model by up to 27x, which makes cold-boot attacks against AES practical even for high error rates."}],"user_id":"15278","ddc":["040"],"language":[{"iso":"eng"}],"date_updated":"2023-09-26T13:33:50Z","doi":"10.1109/FCCM.2014.67","department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"project":[{"grant_number":"160364472","name":"SFB 901","_id":"1"},{"grant_number":"160364472","name":"SFB 901 - Subprojekt C2","_id":"14"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"34","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","grant_number":"610996"}],"title":"Reconstructing AES Key Schedules from Decayed Memory with FPGAs"},{"title":"Self-awareness as a Model for Designing and Operating Heterogeneous Multicores","department":[{"_id":"27"},{"_id":"78"},{"_id":"518"}],"project":[{"grant_number":"160364472","name":"SFB 901","_id":"1"},{"_id":"14","name":"SFB 901 - Subprojekt C2","grant_number":"160364472"},{"_id":"4","name":"SFB 901 - Project Area C"},{"grant_number":"257906","name":"Engineering Proprioception in Computing Systems","_id":"31"}],"date_updated":"2023-09-26T13:33:31Z","doi":"10.1145/2617596","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"Self-aware computing is a paradigm for structuring and simplifying the design and operation of computing systems that face unprecedented levels of system dynamics and thus require novel forms of adaptivity. The generality of the paradigm makes it applicable to many types of computing systems and, previously, researchers started to introduce concepts of self-awareness to multicore architectures. In our work we build on a recent reference architectural framework as a model for self-aware computing and instantiate it for an FPGA-based heterogeneous multicore running the ReconOS reconfigurable architecture and operating system. After presenting the model for self-aware computing and ReconOS, we demonstrate with a case study how a multicore application built on the principle of self-awareness, autonomously adapts to changes in the workload and system state. Our work shows that the reference architectural framework as a model for self-aware computing can be practically applied and allows us to structure and simplify the design process, which is essential for designing complex future computing systems."}],"ddc":["040"],"user_id":"15278","author":[{"last_name":"Agne","full_name":"Agne, Andreas","first_name":"Andreas"},{"last_name":"Happe","full_name":"Happe, Markus","first_name":"Markus"},{"full_name":"Lösch, Achim","first_name":"Achim","id":"43646","last_name":"Lösch"},{"last_name":"Plessl","id":"16153","first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982"},{"last_name":"Platzner","id":"398","first_name":"Marco","full_name":"Platzner, Marco"}],"publisher":"ACM","quality_controlled":"1","file_date_updated":"2018-03-20T07:19:19Z","publication":"ACM Transactions on Reconfigurable Technology and Systems (TRETS)","file":[{"file_name":"365-plessl14_trets_01.pdf","date_created":"2018-03-20T07:19:19Z","access_level":"closed","file_size":916052,"file_id":"1406","creator":"florida","content_type":"application/pdf","date_updated":"2018-03-20T07:19:19Z","relation":"main_file","success":1}],"volume":7,"has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:42:03Z","intvolume":" 7","_id":"365","article_number":"13","issue":"2","type":"journal_article","year":"2014","citation":{"ama":"Agne A, Happe M, Lösch A, Plessl C, Platzner M.

However, whenthe sequential code is executed on a host CPU and only dataparallelloops are executed on an FPGA coprocessor, a sufficientlylarge number of loop iterations (trip counts) is required, such thatthe control- and data-transfer overheads to the coprocessor canbe amortized. However, the trip count of large data-parallel loopsis frequently not known at compile time, but only at runtime justbefore entering a loop. Therefore, we propose to generate codeboth for the CPU and the coprocessor, and to defer the decisionwhere to execute the appropriate code to the runtime of theapplication when the trip count of the loop can be determinedjust at runtime. We demonstrate how an LLVM compiler basedtoolflow can automatically insert appropriate decision blocks intothe application code. Analyzing popular benchmark suites, weshow that this kind of runtime decisions is often applicable. Thepractical feasibility of our approach is demonstrated by a toolflowthat automatically identifies loops suitable for vectorization andgenerates code for the FPGA coprocessor of a Convey HC-1. Thetoolflow adds decisions based on a comparison of the runtimecomputedtrip counts to thresholds for specific loops and alsoincludes support to move just the required data to the coprocessor.We evaluate the integrated toolflow with characteristic loopsexecuted on different input data sizes.","lang":"eng"}],"has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:42:17Z","publisher":"IEEE","author":[{"first_name":"Gavin Francis","full_name":"Vaz, Gavin Francis","last_name":"Vaz","id":"30332"},{"full_name":"Riebler, Heinrich","first_name":"Heinrich","id":"8961","last_name":"Riebler"},{"id":"3145","last_name":"Kenter","full_name":"Kenter, Tobias","first_name":"Tobias"},{"first_name":"Christian","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","last_name":"Plessl","id":"16153"}],"quality_controlled":"1","file_date_updated":"2018-03-16T11:29:52Z","publication":"Proceedings of the International Conference on ReConFigurable Computing and FPGAs (ReConFig)","file":[{"file_size":557362,"creator":"florida","file_id":"1353","content_type":"application/pdf","date_updated":"2018-03-16T11:29:52Z","relation":"main_file","success":1,"date_created":"2018-03-16T11:29:52Z","file_name":"439-plessl14a_reconfig.pdf","access_level":"closed"}]},{"user_id":"15278","ddc":["040"],"abstract":[{"lang":"eng","text":"Stereo-matching algorithms recently received a lot of attention from the FPGA acceleration community. Presented solutions range from simple, very resource efficient systems with modest matching quality for small embedded systems to sophisticated algorithms with several processing steps, implemented on big FPGAs. In order to achieve high throughput, most implementations strongly focus on pipelining and data reuse between different computation steps. This approach leads to high efficiency, but limits the supported computation patterns and due the high integration of the implementation, adaptions to the algorithm are difficult. In this work, we present a stereo-matching implementation, that starts by offloading individual kernels from the CPU to the FPGA. Between subsequent compute steps on the FPGA, data is stored off-chip in on-board memory of the FPGA accelerator card. This enables us to accelerate the AD-census algorithm with cross-based aggregation and scanline optimization for the first time without algorithmic changes and for up to full HD image dimensions. Analyzing throughput and bandwidth requirements, we outline some trade-offs that are involved with this approach, compared to tighter integration of more kernel loops into one design."}],"date_created":"2017-10-17T12:42:11Z","status":"public","has_accepted_license":"1","file":[{"date_updated":"2018-03-16T11:37:42Z","content_type":"application/pdf","success":1,"relation":"main_file","file_size":932852,"creator":"florida","file_id":"1366","access_level":"closed","date_created":"2018-03-16T11:37:42Z","file_name":"406-ReConFig14.pdf"}],"publication":"Proceedings of the International Conference on ReConFigurable Computing and FPGAs (ReConFig)","file_date_updated":"2018-03-16T11:37:42Z","publisher":"IEEE","author":[{"last_name":"Kenter","id":"3145","first_name":"Tobias","full_name":"Kenter, Tobias"},{"last_name":"Schmitz","full_name":"Schmitz, Henning","first_name":"Henning"},{"last_name":"Plessl","id":"16153","first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982"}],"quality_controlled":"1","_id":"406","page":"1-8","citation":{"mla":"Kenter, Tobias, et al. “Kernel-Centric Acceleration of High Accuracy Stereo-Matching.” Proceedings of the International Conference on ReConFigurable Computing and FPGAs (ReConFig), IEEE, 2014, pp. 1–8, doi:10.1109/ReConFig.2014.7032535.","bibtex":"@inproceedings{Kenter_Schmitz_Plessl_2014, title={Kernel-Centric Acceleration of High Accuracy Stereo-Matching}, DOI={10.1109/ReConFig.2014.7032535}, booktitle={Proceedings of the International Conference on ReConFigurable Computing and FPGAs (ReConFig)}, publisher={IEEE}, author={Kenter, Tobias and Schmitz, Henning and Plessl, Christian}, year={2014}, pages={1–8} }","chicago":"Kenter, Tobias, Henning Schmitz, and Christian Plessl. “Kernel-Centric Acceleration of High Accuracy Stereo-Matching.” In Proceedings of the International Conference on ReConFigurable Computing and FPGAs (ReConFig), 1–8.

Instead the contents decay rather slowly, in particular if the DRAM chips are cooled to low temperatures. This effect opens an attack vector on cryptographic applications that keep decrypted keys in DRAM. An attacker with access to the target computer can reboot it or remove the RAM modules and quickly copy the RAM contents to non-volatile memory. By exploiting the known cryptographic structure of the cipher and layout of the key data in memory, in our application an AES key schedule with redundancy, the resulting memory image can be searched for sections that could correspond to decayed cryptographic keys; then, the attacker can attempt to reconstruct the original key. However, the runtime of these algorithms grows rapidly with increasing memory image size, error rate and complexity of the bit error model, which limits the practicability of the approach.In this work, we study how the algorithm for key search can be accelerated with custom computing machines. We present an FPGA-based architecture on a Maxeler dataflow computing system that outperforms a software implementation up to 205x, which significantly improves the practicability of cold-attacks against AES."}],"ddc":["040"],"user_id":"15278","language":[{"iso":"eng"}],"date_updated":"2023-09-26T13:37:35Z","doi":"10.1109/FPT.2013.6718394","department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"project":[{"name":"SFB 901","grant_number":"160364472","_id":"1"},{"_id":"14","name":"SFB 901 - Subprojekt C2","grant_number":"160364472"},{"name":"SFB 901 - Subproject C1","_id":"13"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"34","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","grant_number":"610996"}],"title":"FPGA-accelerated Key Search for Cold-Boot Attacks against AES"},{"department":[{"_id":"63"},{"_id":"27"},{"_id":"518"},{"_id":"78"}],"project":[{"_id":"1","grant_number":"160364472","name":"SFB 901"},{"name":"SFB 901 - Subprojekt C2","grant_number":"160364472","_id":"14"},{"name":"SFB 901 - Project Area C","_id":"4"}],"title":"On-The-Fly Computing: A Novel Paradigm for Individualized IT Services","language":[{"iso":"eng"}],"date_updated":"2023-09-26T13:38:20Z","doi":"10.1109/ISORC.2013.6913232","file":[{"file_name":"505-Plessl13_seus.pdf","date_created":"2018-03-15T13:38:56Z","access_level":"closed","file_size":1040834,"file_id":"1308","creator":"florida","content_type":"application/pdf","date_updated":"2018-03-15T13:38:56Z","success":1,"relation":"main_file"}],"publisher":"IEEE","author":[{"first_name":"Markus","full_name":"Happe, Markus","last_name":"Happe"},{"first_name":"Peter","full_name":"Kling, Peter","last_name":"Kling"},{"last_name":"Plessl","id":"16153","first_name":"Christian","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian"},{"full_name":"Platzner, Marco","first_name":"Marco","id":"398","last_name":"Platzner"},{"id":"15523","last_name":"Meyer auf der Heide","full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm"}],"quality_controlled":"1","file_date_updated":"2018-03-15T13:38:56Z","publication":"Proceedings of the 9th IEEE Workshop on Software Technology for Future embedded and Ubiquitous Systems (SEUS)","status":"public","has_accepted_license":"1","date_created":"2017-10-17T12:42:30Z","abstract":[{"text":"In this paper we introduce “On-The-Fly Computing”, our vision of future IT services that will be provided by assembling modular software components available on world-wide markets.

We envision that these future compute centers will continue to leverage three current trends in large scale computing which are an increasing amount of parallel processing, a trend to use heterogeneous computing resources, and—in the light of rising energy cost—energy-efficiency as a primary goal in the design and operation of computing systems.

A promising but hardly investigated approach is to develop tool flows that keep the common languages for scientific code (C,C++, and Fortran) and allow the developer to augment the source code with OpenMPlike directives for instructing the compiler which parts of the application shall be offloaded the FPGA accelerator.\r\nIn this work we study whether the promise of effective FPGA acceleration with an OpenMP-like programming effort\r\ncan actually be held. Our target system is the Convey HC-1 reconfigurable computer for which an OpenMP-like\r\nprogramming environment exists. As case study we use an application from computational nanophotonics. Our results\r\nshow that a developer without previous FPGA experience could create an FPGA-accelerated application that is competitive to an optimized OpenMP-parallelized CPU version running on a two socket quad-core server. Finally, we discuss our experiences with this tool flow and the Convey HC-1 from a productivity and economic point of view.","lang":"eng"}],"date_created":"2018-03-29T15:04:25Z","has_accepted_license":"1","status":"public","file":[{"file_size":2148787,"file_id":"7638","creator":"fossie","date_updated":"2019-02-13T09:04:46Z","content_type":"application/pdf","relation":"main_file","success":1,"file_name":"2012-11 Meyer,Schumacher,Plessl,Förstner_Convey vector personalities-FPGA acceleratin with an openmp-like programming effort.pdf","date_created":"2019-02-13T09:04:46Z","access_level":"closed"}],"keyword":["funding-upb-forschungspreis","funding-maxup","tet_topic_hpc"],"file_date_updated":"2019-02-13T09:04:46Z","publication":"Proc.

Most researchers rely on temperature simulations to evaluate their novel thermal management techniques. However, the accuracy of the simulations is to some extent questionable and they require a high computational effort if a detailed thermal model is used.For experimental evaluation of real-world temperature management methods, often synthetic heat sources are employed. Therefore, in this paper we investigated the question if we can create significant rises in temperature on modern FPGAs to enable future evaluation of thermal management techniques based on experiments in contrast to simulations. Therefore, we have developed eight different heat-generating cores that use different subsets of the FPGA resources. Our experimental results show that, according to the built-in thermal diode of our Xilinx Virtex-5 FPGA, we can increase the chip temperature by 134 degree C in less than 12 minutes by only utilizing about 21% of the slices.","lang":"eng"}],"has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:42:51Z","file":[{"date_created":"2018-03-15T06:48:32Z","file_name":"615-ReConFig12_01.pdf","access_level":"closed","file_size":730144,"creator":"florida","file_id":"1246","content_type":"application/pdf","date_updated":"2018-03-15T06:48:32Z","relation":"main_file","success":1}],"author":[{"last_name":"Happe","full_name":"Happe, Markus","first_name":"Markus"},{"last_name":"Hangmann","first_name":"Hendrik","full_name":"Hangmann, Hendrik"},{"first_name":"Andreas","full_name":"Agne, Andreas","last_name":"Agne"},{"id":"16153","last_name":"Plessl","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","first_name":"Christian"}],"quality_controlled":"1","publisher":"IEEE","publication":"Proceedings of the International Conference on Reconfigurable Computing and FPGAs (ReConFig)","file_date_updated":"2018-03-15T06:48:32Z"},{"abstract":[{"text":"One major obstacle for a wide spread FPGA usage in general-purpose computing is the development tool flow that requires much higher effort than for pure software solutions.

We investigate this approach for a stereo matching algorithm that has abundant parallelism and a number of different computational patterns. We note that for this case study the automated vectorization in its current state doesn’t hold its productivity promise. However, we also show that using the Vector Personality can yield a significant speedups compared to CPU implementations in two of three investigated phases of the algorithm. Those speedups don’t match custom FPGA implementations, but can come with much reduced development effort.","lang":"eng"}],"ddc":["040"],"user_id":"15278","publisher":"IEEE","quality_controlled":"1","author":[{"full_name":"Kenter, Tobias","first_name":"Tobias","id":"3145","last_name":"Kenter"},{"id":"16153","last_name":"Plessl","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","first_name":"Christian"},{"full_name":"Schmitz, Henning","first_name":"Henning","last_name":"Schmitz"}],"file_date_updated":"2018-03-15T08:33:18Z","publication":"Proceedings of the International Conference on ReConFigurable Computing and FPGAs (ReConFig)","file":[{"file_name":"591-ReConFig2012Kenter_Schmitz_Plessl.pdf","date_created":"2018-03-15T08:33:18Z","access_level":"closed","file_id":"1257","creator":"florida","file_size":371235,"relation":"main_file","success":1,"content_type":"application/pdf","date_updated":"2018-03-15T08:33:18Z"}],"status":"public","has_accepted_license":"1","date_created":"2017-10-17T12:42:47Z","_id":"591","type":"conference","citation":{"ieee":"T.
