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."}],"ddc":["040"],"user_id":"15278","publication":"International Journal of Reconfigurable Computing (IJRC)","file_date_updated":"2018-03-20T07:47:56Z","author":[{"id":"3145","last_name":"Kenter","full_name":"Kenter, Tobias","first_name":"Tobias"},{"last_name":"Schmitz","first_name":"Henning","full_name":"Schmitz, Henning"},{"orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","first_name":"Christian","id":"16153","last_name":"Plessl"}],"publisher":"Hindawi","quality_controlled":"1","file":[{"content_type":"application/pdf","date_updated":"2018-03-20T07:47:56Z","relation":"main_file","success":1,"file_size":2993898,"creator":"florida","file_id":"1444","access_level":"closed","date_created":"2018-03-20T07:47:56Z","file_name":"296-859425.pdf"}],"volume":2015,"date_created":"2017-10-17T12:41:49Z","status":"public","has_accepted_license":"1","date_updated":"2023-09-26T13:29:08Z","doi":"10.1155/2015/859425","language":[{"iso":"eng"}],"title":"Exploring Tradeoffs between Specialized Kernels and a Reusable Overlay in a Stereo-Matching Case Study","department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"project":[{"_id":"1","grant_number":"160364472","name":"SFB 901"},{"_id":"14","name":"SFB 901 - Subprojekt C2","grant_number":"160364472"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","grant_number":"610996","_id":"34"}]},{"title":"Easy-to-Use On-The-Fly Binary Program Acceleration on Many-Cores","external_id":{"arxiv":["1412.3906"]},"project":[{"_id":"1","name":"SFB 901","grant_number":"160364472"},{"name":"SFB 901 - Subprojekt C2","grant_number":"160364472","_id":"14"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","grant_number":"610996","_id":"34"}],"department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"oa":"1","date_updated":"2023-09-26T13:29:59Z","language":[{"iso":"eng"}],"ddc":["040"],"user_id":"15278","abstract":[{"lang":"eng","text":"This paper introduces Binary Acceleration At Runtime(BAAR), an easy-to-use on-the-fly binary acceleration mechanismwhich aims to tackle the problem of enabling existentsoftware to automatically utilize accelerators at runtime.

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."}],"user_id":"15278","ddc":["040"],"file":[{"success":1,"relation":"main_file","date_updated":"2018-03-21T10:29:49Z","content_type":"application/pdf","file_id":"1500","creator":"florida","file_size":380552,"access_level":"closed","date_created":"2018-03-21T10:29:49Z","file_name":"238-plessl15_date.pdf"}],"file_date_updated":"2018-03-21T10:29:49Z","publication":"Proceedings of the 2015 Conference on Design, Automation and Test in Europe (DATE)","publisher":"EDA Consortium / IEEE","quality_controlled":"1","author":[{"full_name":"Damschen, Marvin","first_name":"Marvin","last_name":"Damschen"},{"full_name":"Riebler, Heinrich","first_name":"Heinrich","id":"8961","last_name":"Riebler"},{"id":"30332","last_name":"Vaz","full_name":"Vaz, Gavin Francis","first_name":"Gavin Francis"},{"id":"16153","last_name":"Plessl","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","first_name":"Christian"}],"date_created":"2017-10-17T12:41:38Z","has_accepted_license":"1","status":"public","date_updated":"2023-09-26T13:31:44Z","doi":"10.7873/DATE.2015.1124","language":[{"iso":"eng"}],"title":"Transparent offloading of computational hotspots from binary code to Xeon Phi","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 - Project Area C","_id":"4"},{"_id":"34","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","grant_number":"610996"}]},{"abstract":[{"text":"The ATLAS experiment at CERN is planning full deployment of a new unified optical link technology for connecting detector front end electronics on the timescale of the LHC Run 4 (2025). It is estimated that roughly 8000 GBT (GigaBit Transceiver) links, with transfer rates up to 10.24 Gbps, will replace existing links used for readout, detector control and distribution of timing and trigger information. 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). FELIX implies architectural changes to the ATLAS data acquisition system, such as the use of industry standard COTS components early in the DAQ chain. Additionally the design and implementation of a FELIX demonstration platform is presented and hardware and software aspects will be discussed.","lang":"eng"}],"title":"FELIX: a High-Throughput Network Approach for Interfacing to Front End Electronics for ATLAS Upgrades","user_id":"15278","department":[{"_id":"27"},{"_id":"518"}],"publication":"Journal of Physics: Conference Series","author":[{"last_name":"Anderson","first_name":"J","full_name":"Anderson, J"},{"full_name":"Borga, A","first_name":"A","last_name":"Borga"},{"full_name":"Boterenbrood, H","first_name":"H","last_name":"Boterenbrood"},{"last_name":"Chen","first_name":"H","full_name":"Chen, H"},{"last_name":"Chen","full_name":"Chen, K","first_name":"K"},{"last_name":"Drake","full_name":"Drake, G","first_name":"G"},{"full_name":"Francis, D","first_name":"D","last_name":"Francis"},{"full_name":"Gorini, B","first_name":"B","last_name":"Gorini"},{"full_name":"Lanni, F","first_name":"F","last_name":"Lanni"},{"full_name":"Lehmann Miotto, G","first_name":"G","last_name":"Lehmann Miotto"},{"first_name":"L","full_name":"Levinson, L","last_name":"Levinson"},{"first_name":"J","full_name":"Narevicius, J","last_name":"Narevicius"},{"first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","last_name":"Plessl","id":"16153"},{"last_name":"Roich","full_name":"Roich, A","first_name":"A"},{"last_name":"Ryu","first_name":"S","full_name":"Ryu, S"},{"last_name":"Schreuder","full_name":"Schreuder, F","first_name":"F"},{"last_name":"Schumacher","first_name":"Jörn","full_name":"Schumacher, Jörn"},{"last_name":"Vandelli","full_name":"Vandelli, Wainer","first_name":"Wainer"},{"full_name":"Vermeulen, J","first_name":"J","last_name":"Vermeulen"},{"first_name":"J","full_name":"Zhang, J","last_name":"Zhang"}],"quality_controlled":"1","publisher":"IOP Publishing","volume":664,"date_created":"2018-03-23T14:19:27Z","status":"public","date_updated":"2023-09-26T13:31:23Z","_id":"1775","intvolume":" 664","doi":"10.1088/1742-6596/664/8/082050","article_number":"082050","type":"journal_article","year":"2015","citation":{"bibtex":"@article{Anderson_Borga_Boterenbrood_Chen_Chen_Drake_Francis_Gorini_Lanni_Lehmann Miotto_et al._2015, title={FELIX: a High-Throughput Network Approach for Interfacing to Front End Electronics for ATLAS Upgrades}, volume={664}, DOI={10.1088/1742-6596/664/8/082050}, number={082050}, journal={Journal of Physics: Conference Series}, publisher={IOP Publishing}, author={Anderson, J and Borga, A and Boterenbrood, H and Chen, H and Chen, K and Drake, G and Francis, D and Gorini, B and Lanni, F and Lehmann Miotto, G and et al.}, year={2015} }","mla":"Anderson, J., et al. “FELIX: A High-Throughput Network Approach for Interfacing to Front End Electronics for ATLAS Upgrades.” Journal of Physics: Conference Series, vol. 664, 082050, IOP Publishing, 2015, doi:10.1088/1742-6596/664/8/082050.","chicago":"Anderson, J, A Borga, H Boterenbrood, H Chen, K Chen, G Drake, D Francis, et al. “FELIX: A High-Throughput Network Approach for Interfacing to Front End Electronics for ATLAS Upgrades.” Journal of Physics: Conference Series 664 (2015). https://doi.org/10.1088/1742-6596/664/8/082050.","ama":"Anderson J, Borga A, Boterenbrood H, et al.

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. Diese Technologie f{\\\"u}hrt zu einer durchl{\\\"a}ssigen Grenze zwischen Hardware und Software bzw. l{\\\"o}st sie die herk{\\\"o}mmliche Vorstellung einer festen Hardware und einer flexiblen Software damit auf.","lang":"eng"}],"user_id":"15278","ddc":["040"],"series_title":"Schriftenreihe des Graduiertenkollegs \"Automatismen\"","language":[{"iso":"ger"}],"date_updated":"2023-09-26T13:32:49Z","department":[{"_id":"518"},{"_id":"27"},{"_id":"78"}],"project":[{"name":"SFB 901","grant_number":"160364472","_id":"1"},{"_id":"14","name":"SFB 901 - Subprojekt C2","grant_number":"160364472"},{"name":"SFB 901 - Project Area C","_id":"4"}],"editor":[{"last_name":"Künsemöller","first_name":"Jörn","full_name":"Künsemöller, Jörn"},{"last_name":"Eke","first_name":"Norber Otto","full_name":"Eke, Norber Otto"},{"first_name":"Lioba","full_name":"Foit, Lioba","last_name":"Foit"},{"first_name":"Timo","full_name":"Kaerlein, Timo","last_name":"Kaerlein"}],"publication_status":"published","publication_identifier":{"isbn":["978-3-7705-5730-1"]},"place":"Paderborn","title":"Verschiebungen an der Grenze zwischen Hardware und Software"},{"place":"Cham","title":"Partitioning and Vectorizing Binary Applications for a Reconfigurable Vector Computer","department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"project":[{"grant_number":"160364472","name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt C2","grant_number":"160364472","_id":"14"},{"_id":"4","name":"SFB 901 - Project Area C"},{"grant_number":"610996","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","_id":"34"}],"date_updated":"2023-09-26T13:34:08Z","doi":"10.1007/978-3-319-05960-0_13","series_title":"Lecture Notes in Computer Science (LNCS)","language":[{"iso":"eng"}],"abstract":[{"text":"In order to leverage the use of reconfigurable architectures in general-purpose computing, quick and automated methods to find suitable accelerator designs are required.

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"],"language":[{"iso":"eng"}],"date_updated":"2023-09-26T13:33:06Z","doi":"10.1016/j.micpro.2013.12.001","department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"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"},{"_id":"31","name":"Engineering Proprioception in Computing Systems","grant_number":"257906"}],"title":"Seven Recipes for Setting Your FPGA on Fire – A Cookbook on Heat Generators"},{"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"},{"_id":"4","name":"SFB 901 - Project Area C"},{"grant_number":"610996","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","_id":"34"}],"title":"Reconstructing AES Key Schedules from Decayed Memory with FPGAs","page":"222-229","citation":{"short":"H.

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.","lang":"eng"}],"user_id":"15278","ddc":["040"]},{"doi":"10.1145/2617596","date_updated":"2023-09-26T13:33:31Z","language":[{"iso":"eng"}],"title":"Self-awareness as a Model for Designing and Operating Heterogeneous Multicores","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"},{"grant_number":"257906","name":"Engineering Proprioception in Computing Systems","_id":"31"}],"department":[{"_id":"27"},{"_id":"78"},{"_id":"518"}],"article_number":"13","issue":"2","intvolume":" 7","_id":"365","type":"journal_article","citation":{"chicago":"Agne, Andreas, Markus Happe, Achim Lösch, Christian Plessl, and Marco Platzner. “Self-Awareness as a Model for Designing and Operating Heterogeneous Multicores.” ACM Transactions on Reconfigurable Technology and Systems (TRETS) 7, no. 2 (2014). https://doi.org/10.1145/2617596.","ama":"Agne A, Happe M, Lösch A, Plessl C, Platzner M.

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.

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.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1109/ReConFig.2014.7032535","date_updated":"2023-09-26T13:36:40Z","project":[{"name":"SFB 901","grant_number":"160364472","_id":"1"},{"_id":"14","name":"SFB 901 - Subprojekt C2","grant_number":"160364472"},{"name":"SFB 901 - Project Area C","_id":"4"},{"grant_number":"610996","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","_id":"34"}],"department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"title":"Kernel-Centric Acceleration of High Accuracy Stereo-Matching"},{"doi":"10.1007/978-3-319-05960-0_38","_id":"1780","date_updated":"2023-09-26T13:36:20Z","language":[{"iso":"eng"}],"type":"conference","year":"2014","citation":{"ama":"C.

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.","lang":"eng"}],"user_id":"15278","ddc":["040"],"file":[{"creator":"florida","file_id":"1294","file_size":822680,"relation":"main_file","success":1,"content_type":"application/pdf","date_updated":"2018-03-15T10:36:08Z","file_name":"528-plessl13_fpt.pdf","date_created":"2018-03-15T10:36:08Z","access_level":"closed"}],"quality_controlled":"1","author":[{"first_name":"Heinrich","full_name":"Riebler, Heinrich","last_name":"Riebler","id":"8961"},{"first_name":"Tobias","full_name":"Kenter, Tobias","last_name":"Kenter","id":"3145"},{"first_name":"Christoph","full_name":"Sorge, Christoph","last_name":"Sorge"},{"last_name":"Plessl","id":"16153","first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982"}],"publisher":"IEEE","file_date_updated":"2018-03-15T10:36:08Z","keyword":["coldboot"],"publication":"Proceedings of the International Conference on Field-Programmable Technology (FPT)","has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:42:35Z"},{"type":"conference","year":"2013","citation":{"ieee":"M.

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."}],"date_created":"2017-10-17T12:42:51Z","status":"public","has_accepted_license":"1","file_date_updated":"2018-03-15T06:48:32Z","publication":"Proceedings of the International Conference on Reconfigurable Computing and FPGAs (ReConFig)","author":[{"first_name":"Markus","full_name":"Happe, Markus","last_name":"Happe"},{"full_name":"Hangmann, Hendrik","first_name":"Hendrik","last_name":"Hangmann"},{"last_name":"Agne","full_name":"Agne, Andreas","first_name":"Andreas"},{"first_name":"Christian","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","last_name":"Plessl","id":"16153"}],"publisher":"IEEE","quality_controlled":"1","file":[{"content_type":"application/pdf","date_updated":"2018-03-15T06:48:32Z","relation":"main_file","success":1,"file_size":730144,"creator":"florida","file_id":"1246","access_level":"closed","file_name":"615-ReConFig12_01.pdf","date_created":"2018-03-15T06:48:32Z"}],"doi":"10.1109/ReConFig.2012.6416745","date_updated":"2023-09-26T13:42:26Z","language":[{"iso":"eng"}],"title":"Eight Ways to put your FPGA on Fire – A Systematic Study of Heat Generators","project":[{"_id":"1","name":"SFB 901","grant_number":"160364472"},{"_id":"14","grant_number":"160364472","name":"SFB 901 - Subprojekt C2"},{"name":"SFB 901 - Project Area C","_id":"4"},{"grant_number":"257906","name":"Engineering Proprioception in Computing Systems","_id":"31"}],"department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}]},{"title":"Pragma based parallelization - Trading hardware efficiency for ease of use?","project":[{"name":"SFB 901","grant_number":"160364472","_id":"1"},{"grant_number":"160364472","name":"SFB 901 - Subprojekt C2","_id":"14"},{"_id":"4","name":"SFB 901 - Project Area C"},{"_id":"31","grant_number":"257906","name":"Engineering Proprioception in Computing Systems"}],"department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"doi":"10.1109/ReConFig.2012.6416773","date_updated":"2023-09-26T13:41:08Z","language":[{"iso":"eng"}],"ddc":["040"],"user_id":"15278","abstract":[{"lang":"eng","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.

Hence, novel design and operation principles and methods are needed that possibly break drastically with the static ones we have built into our systems and the fixed abstraction layers we have cherished over the last decades. Thus, we propose a HW/SW platform that collects and maintains information about its state and progress which enables the system to reason about its behavior (self-awareness) and utilizes its knowledge to effectively and autonomously adapt its behavior to changing requirements (self-expression).To enable self-awareness, our compute nodes collect information using a variety of sensors, i.e. performance counters and thermal diodes, and use internal self-awareness models that process these information. For self-awareness, on-line learning is crucial such that the node learns and continuously updates its models at run-time to react to changing conditions. To enable self-expression, we break with the classic design-time abstraction layers of hardware, operating system and software. In contrast, our system is able to vertically migrate functionalities between the layers at run-time to exploit trade-offs between abstraction and optimization.This paper presents a heterogeneous multi-core architecture, that enables self-awareness and self-expression, an operating system for our proposed hardware/software platform and a novel self-expression method."}],"ddc":["040"],"user_id":"15278","file_date_updated":"2018-03-15T08:14:17Z","publication":"Proceedings of the Workshop on Self-Awareness in Reconfigurable Computing Systems (SRCS)","author":[{"first_name":"Markus","full_name":"Happe, Markus","last_name":"Happe"},{"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"},{"id":"398","last_name":"Platzner","full_name":"Platzner, Marco","first_name":"Marco"}],"quality_controlled":"1","file":[{"date_created":"2018-03-15T08:14:17Z","file_name":"609-happe12_fpl_awareness.pdf","access_level":"closed","file_size":146789,"creator":"florida","file_id":"1249","content_type":"application/pdf","date_updated":"2018-03-15T08:14:17Z","relation":"main_file","success":1}],"date_created":"2017-10-17T12:42:50Z","status":"public","has_accepted_license":"1","_id":"609","page":"8-9","citation":{"short":"M.

In practice, while some applications meet the performance expectations, heterogeneous architectures still require a tremendous effort from the application developers. This work presents a code generation method to port codes into heterogeneous platforms, based on transformations of the control flow into function calls. The results show that the cost of the function-call mechanism is affordable for the tested HPC kernels. The complete toolchain, based on the LLVM compiler infrastructure, is fully automated once the sequential specification is provided.","lang":"eng"}],"status":"public","has_accepted_license":"1","date_created":"2017-10-17T12:42:42Z","file":[{"success":1,"relation":"main_file","date_updated":"2018-03-15T10:20:24Z","content_type":"application/pdf","file_id":"1275","creator":"florida","file_size":288508,"access_level":"closed","file_name":"567-ba-ca-12a.pdf","date_created":"2018-03-15T10:20:24Z"}],"author":[{"last_name":"Barrio","first_name":"Pablo","full_name":"Barrio, Pablo"},{"full_name":"Carreras, Carlos","first_name":"Carlos","last_name":"Carreras"},{"last_name":"Sierra","first_name":"Roberto","full_name":"Sierra, Roberto"},{"last_name":"Kenter","id":"3145","first_name":"Tobias","full_name":"Kenter, Tobias"},{"id":"16153","last_name":"Plessl","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","first_name":"Christian"}],"publisher":"IEEE","quality_controlled":"1","file_date_updated":"2018-03-15T10:20:24Z","publication":"Proceedings of the International Conference on High Performance Computing and Simulation (HPCS)","_id":"567","citation":{"ieee":"P.

Temperature-aware thread mapping strategies are key for providing dependability in such systems. These strategies rely on measuring the temperature distribution and redicting the thermal behavior of the system when there are changes to the hardware and software running on the FPGA. While there are a number of tools that use thermal models to predict temperature distributions at design time, these tools lack the flexibility to autonomously adjust to changing FPGA configurations. To address this problem we propose a temperature-aware system that empowers FPGA-based reconfigurable multi-cores to autonomously predict the on-chip temperature distribution for pro-active thread remapping. Our system obtains temperature measurements through a self-calibrating grid of sensors and uses area constrained heat-generating circuits in order to generate spatial and temporal temperature gradients. The generated temperature variations are then used to learn the free parameters of the system's thermal model. The system thus acquires an understanding of its own thermal characteristics. We implemented an FPGA system containing a net of 144 temperature sensors on a Xilinx Virtex-6 LX240T FPGA that is aware of its thermal model. Finally, we show that the temperature predictions vary less than 0.72 degree C on average compared to the measured temperature distributions at run-time."}],"user_id":"15278","ddc":["040"],"citation":{"mla":"Happe, Markus, et al. “Measuring and Predicting Temperature Distributions on FPGAs at Run-Time.” Proceedings of the 2011 International Conference on Reconfigurable Computing and FPGAs (ReConFig), IEEE, 2011, pp. 55–60, doi:10.1109/ReConFig.2011.59.","bibtex":"@inproceedings{Happe_Agne_Plessl_2011, title={Measuring and Predicting Temperature Distributions on FPGAs at Run-Time}, DOI={10.1109/ReConFig.2011.59}, booktitle={Proceedings of the 2011 International Conference on Reconfigurable Computing and FPGAs (ReConFig)}, publisher={IEEE}, author={Happe, Markus and Agne, Andreas and Plessl, Christian}, year={2011}, pages={55–60} }","ama":"Happe M, Agne A, Plessl C.
