In practical simulations, several trillions of ERIs may have to be\r\ncomputed for every time step.\r\nIn this work, we investigate FPGAs as accelerators for the ERI computation. We use template parameters, here within the Intel oneAPI tool flow, to create customized designs for 256 different ERI quartet classes, based on their orbitals. To maximize data reuse, all intermediates are buffered in FPGA on-chip memory with customized layout. The pre-calculation of intermediates also helps to overcome data dependencies caused by multi-dimensional recurrence\r\nrelations. The involved loop structures are partially or even fully unrolled for high throughput of FPGA kernels. Furthermore, a lossy compression algorithm utilizing arbitrary bitwidth integers is integrated in the FPGA kernels. To our\r\nbest knowledge, this is the first work on ERI computation on FPGAs that supports more than just the single most basic quartet class. Also, the integration of ERI computation and compression it a novelty that is not even covered by CPU or GPU libraries so far.\r\nOur evaluation shows that using 16-bit integer for the ERI compression, the fastest FPGA kernels exceed the performance of 10 GERIS ($10 \\times 10^9$ ERIs per second) on one Intel Stratix 10 GX 2800 FPGA, with maximum absolute errors around $10^{-7}$ - $10^{-5}$ Hartree. The measured throughput can be accurately explained by a performance model. The FPGA kernels deployed on 2 FPGAs outperform similar computations using the widely used libint reference on a two-socket server with 40 Xeon Gold 6148 CPU cores of the same process technology by factors up to 6.0x and on a new two-socket server with 128 EPYC 7713 CPU cores by up to 1.9x.","lang":"eng"}],"language":[{"iso":"eng"}],"page":"162-173","type":"conference","citation":{"bibtex":"@inproceedings{Wu_Kenter_Schade_Kühne_Plessl_2023, title={Computing and Compressing Electron Repulsion Integrals on FPGAs}, DOI={10.1109/FCCM57271.2023.00026}, booktitle={2023 IEEE 31st Annual International Symposium on Field-Programmable Custom Computing Machines (FCCM)}, author={Wu, Xin and Kenter, Tobias and Schade, Robert and Kühne, Thomas and Plessl, Christian}, year={2023}, pages={162–173} }","mla":"Wu, Xin, et al. “Computing and Compressing Electron Repulsion Integrals on FPGAs.” 2023 IEEE 31st Annual International Symposium on Field-Programmable Custom Computing Machines (FCCM), 2023, pp. 162–73, doi:10.1109/FCCM57271.2023.00026.","ieee":"X.

Julia leverages a unified and coordinated single-language and ecosystem paradigm and has a proven track record of achieving high performance without sacrificing user productivity. These aspects make Julia a viable alternative to high-performance computing's (HPC's) existing and increasingly costly many-body workflow composition strategy in which traditional HPC languages (e.g., Fortran, C, C++) are used for simulations, and higher-level languages (e.g., Python, R, MATLAB) are used for data analysis and interactive computing. Julia's rapid growth in language capabilities, package ecosystem, and community make it a promising universal language for HPC. This paper presents the views of a multidisciplinary group of researchers from academia, government, and industry that advocate for an HPC software development paradigm that emphasizes developer productivity, workflow portability, and low barriers for entry. We believe that the Julia programming language, its ecosystem, and its community provide modern and powerful capabilities that enable this group's objectives. Crucially, we believe that Julia can provide a feasible and less costly approach to programming scientific applications and workflows that target HPC facilities. In this work, we examine the current practice and role of Julia as a common, end-to-end programming model to address major challenges in scientific reproducibility, data-driven AI/machine learning, co-design and workflows, scalability and performance portability in heterogeneous computing, network communication, data management, and community education. As a result, the diversification of current investments to fulfill the needs of the upcoming decade is crucial as more supercomputing centers prepare for the exascale era."}],"user_id":"90082","title":"Bridging HPC Communities through the Julia Programming Language","department":[{"_id":"27"}],"author":[{"last_name":"Churavy","full_name":"Churavy, Valentin","first_name":"Valentin"},{"last_name":"Godoy","full_name":"Godoy, William F","first_name":"William F"},{"full_name":"Bauer, Carsten","first_name":"Carsten","id":"90082","last_name":"Bauer"},{"full_name":"Ranocha, Hendrik","first_name":"Hendrik","last_name":"Ranocha"},{"full_name":"Schlottke-Lakemper, Michael","first_name":"Michael","last_name":"Schlottke-Lakemper"},{"last_name":"Räss","first_name":"Ludovic","full_name":"Räss, Ludovic"},{"last_name":"Blaschke","full_name":"Blaschke, Johannes","first_name":"Johannes"},{"full_name":"Giordano, Mosè","first_name":"Mosè","last_name":"Giordano"},{"full_name":"Schnetter, Erik","first_name":"Erik","last_name":"Schnetter"},{"last_name":"Omlin","first_name":"Samuel","full_name":"Omlin, Samuel"},{"full_name":"Vetter, Jeffrey S","first_name":"Jeffrey S","last_name":"Vetter"},{"last_name":"Edelman","full_name":"Edelman, Alan","first_name":"Alan"}],"date_created":"2023-01-16T09:10:48Z","status":"public"},{"date_updated":"2023-07-28T08:03:41Z","_id":"33493","citation":{"chicago":"Gavini, Vikram, Stefano Baroni, Volker Blum, David R.

In order to realize these promises, the\r\ncommunity of electronic structure software developers will however first have\r\nto tackle a number of challenges pertaining to the efficient use of new\r\narchitectures that will rely heavily on massive parallelism and hardware\r\naccelerators. This roadmap provides a broad overview of the state-of-the-art in\r\nelectronic structure calculations and of the various new directions being\r\npursued by the community. It covers 14 electronic structure codes, presenting\r\ntheir current status, their development priorities over the next five years,\r\nand their plans towards tackling the challenges and leveraging the\r\nopportunities presented by the advent of exascale computing."}],"user_id":"75963","title":"Roadmap on Electronic Structure Codes in the Exascale Era","author":[{"full_name":"Gavini, Vikram","first_name":"Vikram","last_name":"Gavini"},{"first_name":"Stefano","full_name":"Baroni, Stefano","last_name":"Baroni"},{"full_name":"Blum, Volker","first_name":"Volker","last_name":"Blum"},{"first_name":"David R.","full_name":"Bowler, David R.","last_name":"Bowler"},{"last_name":"Buccheri","first_name":"Alexander","full_name":"Buccheri, Alexander"},{"full_name":"Chelikowsky, James R.","first_name":"James R.","last_name":"Chelikowsky"},{"last_name":"Das","first_name":"Sambit","full_name":"Das, Sambit"},{"full_name":"Dawson, William","first_name":"William","last_name":"Dawson"},{"first_name":"Pietro","full_name":"Delugas, Pietro","last_name":"Delugas"},{"last_name":"Dogan","first_name":"Mehmet","full_name":"Dogan, Mehmet"},{"last_name":"Draxl","first_name":"Claudia","full_name":"Draxl, Claudia"},{"first_name":"Giulia","full_name":"Galli, Giulia","last_name":"Galli"},{"last_name":"Genovese","first_name":"Luigi","full_name":"Genovese, Luigi"},{"first_name":"Paolo","full_name":"Giannozzi, Paolo","last_name":"Giannozzi"},{"full_name":"Giantomassi, Matteo","first_name":"Matteo","last_name":"Giantomassi"},{"last_name":"Gonze","full_name":"Gonze, Xavier","first_name":"Xavier"},{"full_name":"Govoni, Marco","first_name":"Marco","last_name":"Govoni"},{"full_name":"Gulans, Andris","first_name":"Andris","last_name":"Gulans"},{"last_name":"Gygi","first_name":"François","full_name":"Gygi, François"},{"last_name":"Herbert","first_name":"John M.","full_name":"Herbert, John M."},{"first_name":"Sebastian","full_name":"Kokott, Sebastian","last_name":"Kokott"},{"first_name":"Thomas","full_name":"Kühne, Thomas","last_name":"Kühne","id":"49079"},{"last_name":"Liou","full_name":"Liou, Kai-Hsin","first_name":"Kai-Hsin"},{"last_name":"Miyazaki","first_name":"Tsuyoshi","full_name":"Miyazaki, Tsuyoshi"},{"full_name":"Motamarri, Phani","first_name":"Phani","last_name":"Motamarri"},{"first_name":"Ayako","full_name":"Nakata, Ayako","last_name":"Nakata"},{"full_name":"Pask, John E.","first_name":"John E.","last_name":"Pask"},{"orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","first_name":"Christian","id":"16153","last_name":"Plessl"},{"last_name":"Ratcliff","full_name":"Ratcliff, Laura E.","first_name":"Laura E."},{"last_name":"Richard","first_name":"Ryan M.","full_name":"Richard, Ryan M."},{"last_name":"Rossi","first_name":"Mariana","full_name":"Rossi, Mariana"},{"id":"75963","last_name":"Schade","full_name":"Schade, Robert","orcid":"0000-0002-6268-539","first_name":"Robert"},{"last_name":"Scheffler","first_name":"Matthias","full_name":"Scheffler, Matthias"},{"full_name":"Schütt, Ole","first_name":"Ole","last_name":"Schütt"},{"full_name":"Suryanarayana, Phanish","first_name":"Phanish","last_name":"Suryanarayana"},{"last_name":"Torrent","full_name":"Torrent, Marc","first_name":"Marc"},{"full_name":"Truflandier, Lionel","first_name":"Lionel","last_name":"Truflandier"},{"last_name":"Windus","first_name":"Theresa L.","full_name":"Windus, Theresa L."},{"last_name":"Xu","full_name":"Xu, Qimen","first_name":"Qimen"},{"last_name":"Yu","first_name":"Victor W. -Z.","full_name":"Yu, Victor W. -Z."},{"last_name":"Perez","full_name":"Perez, Danny","first_name":"Danny"}],"department":[{"_id":"27"}],"publication":"arXiv:2209.12747","status":"public","project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"date_created":"2023-08-02T14:59:18Z"},{"language":[{"iso":"eng"}],"year":"2021","citation":{"short":"M.

In this work we report on the\r\nnumerical optimization of the directivity of optical travelling wave antennas\r\nmade from low-loss dielectric materials using full-wave numerical simulations\r\nin conjunction with a particle swarm optimization algorithm. The antennas are\r\ncomposed of a reflector and a director deposited on a glass substrate and an\r\nemitter placed in the feed gap between them serves as an internal source of\r\nexcitation. In particular, we analysed antennas with rectangular- and\r\nhorn-shaped directors made of either Hafnium dioxide or Silicon. The optimized\r\nantennas produce highly directional emission due to the presence of two\r\ndominant guided TE modes in the director in addition to leaky modes. These\r\nguided modes dominate the far-field emission pattern and govern the direction\r\nof the main lobe emission which predominately originates from the end facet of\r\nthe director.

The high level synthesis of OpenCL codes can play a fundamental role for FPGAs in HPC, because it allows to implement different designs with lower development effort compared to hand optimized HDL. However, Stratix 10 cards are still hard to fully exploit using the Intel FPGA SDK for OpenCL. The implementation of designs with thousands of concurrent arithmetic operations often suffers from place and route problems that limit the maximum frequency or entirely prevent a successful synthesis. In order to overcome these issues for the implementation of the matrix multiplication, we formulate Cannon's matrix multiplication algorithm with regard to its efficient synthesis within the FPGA logic. We obtain a two-level block algorithm, where the lower level sub-matrices are multiplied using our Cannon's algorithm implementation. Following this design approach with multiple compute units, we are able to get maximum frequencies close to and above 300 MHz with high utilization of DSP and memory blocks. This allows for performance results above 1 TeraFLOPS.","lang":"eng"}],"user_id":"3145","ddc":["004"],"language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:52:26Z","doi":"10.1109/ICFPT47387.2019.00020","department":[{"_id":"27"},{"_id":"518"}],"project":[{"_id":"33","name":"HighPerMeshes","grant_number":"01|H16005"},{"name":"Performance and Efficiency in HPC with Custom Computing","grant_number":"PL 595/2-1","_id":"32"}],"title":"OpenCL Implementation of Cannon's Matrix Multiplication Algorithm on Intel Stratix 10 FPGAs"},{"doi":"10.1007/978-3-319-77398-8_8","date_updated":"2022-01-06T06:55:22Z","language":[{"iso":"eng"}],"series_title":"Lecture Notes in Computer Science","title":"A Data Structure for Planning Based Workload Management of Heterogeneous HPC Systems","editor":[{"last_name":"Klusáček","full_name":"Klusáček, D.","first_name":"D."},{"first_name":"W.","full_name":"Cirne, W.","last_name":"Cirne"},{"last_name":"Desai","full_name":"Desai, N.","first_name":"N."}],"publication_identifier":{"isbn":["978-3-319-77398-8","978-3-319-77397-1"]},"publication_status":"published","department":[{"_id":"27"}],"intvolume":" 10773","_id":"22","conference":{"location":"Orlando, FL, USA","start_date":"2017-06-02","name":"21st Workshop on Job Scheduling Strategies for Parallel Processing","end_date":"2017-06-02"},"citation":{"bibtex":"@inproceedings{Keller_2018, series={Lecture Notes in Computer Science}, title={A Data Structure for Planning Based Workload Management of Heterogeneous HPC Systems}, volume={10773}, DOI={10.1007/978-3-319-77398-8_8}, booktitle={Proc.

In computational sciences, often more advanced methods are employed that promise better stability, convergence, locality and scaling. Unstructured meshes are shown to be more effective and more accurate, compared to regular grids, in representing computation domains of various shapes. Using unstructured meshes, the discontinuous Galerkin method preserves the ability to perform explicit local update operations for simulations in the time domain. In this work, we investigate FPGAs as target platform for an implementation of the nodal discontinuous Galerkin method to find time-domain solutions of Maxwell's equations in an unstructured mesh. When maximizing data reuse and fitting constant coefficients into suitably partitioned on-chip memory, high computational intensity allows us to implement and feed wide data paths with hundreds of floating point operators. By decoupling off-chip memory accesses from the computations, high memory bandwidth can be sustained, even for the irregular access pattern required by parts of the application. Using the Intel/Altera OpenCL SDK for FPGAs, we present different implementation variants for different polynomial orders of the method. In different phases of the algorithm, either computational or bandwidth limits of the Arria 10 platform are almost reached, thus outperforming a highly multithreaded CPU implementation by around 2x."}],"ddc":["000"],"user_id":"15278","author":[{"full_name":"Kenter, Tobias","first_name":"Tobias","id":"3145","last_name":"Kenter"},{"last_name":"Mahale","full_name":"Mahale, Gopinath","first_name":"Gopinath"},{"first_name":"Samer","full_name":"Alhaddad, Samer","last_name":"Alhaddad","id":"42456"},{"id":"26059","last_name":"Grynko","full_name":"Grynko, Yevgen","first_name":"Yevgen"},{"last_name":"Schmitt","full_name":"Schmitt, Christian","first_name":"Christian"},{"full_name":"Afzal, Ayesha","first_name":"Ayesha","last_name":"Afzal"},{"full_name":"Hannig, Frank","first_name":"Frank","last_name":"Hannig"},{"first_name":"Jens","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens","last_name":"Förstner","id":"158"},{"first_name":"Christian","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","last_name":"Plessl","id":"16153"}],"quality_controlled":"1","publisher":"IEEE","publication":"Proc.

Following the idea of Approximate Computing, we allow imprecision in the final result in order to utilize the sparsity of the input matrix and to allow massively parallel execution. For an n x n matrix, the proposed algorithm allows to distribute the calculations over n nodes with only little communication overhead. The result matrix exhibits the same sparsity pattern as the input matrix, allowing for efficient reuse of allocated data structures.\r\n\r\nWe evaluate the algorithm with respect to the error that it introduces into calculated results, as well as its performance and scalability. We demonstrate that the error is relatively limited for well-conditioned matrices and that results are still valuable for error-resilient applications like preconditioning even for ill-conditioned matrices. We discuss the execution time and scaling of the algorithm on a theoretical level and present a distributed implementation of the algorithm using MPI and OpenMP. We demonstrate the scalability of this implementation by running it on a high-performance compute cluster comprised of 1024 CPU cores, showing a speedup of 665x compared to single-threaded execution.","lang":"eng"}],"user_id":"15278","language":[{"iso":"eng"}],"date_updated":"2023-09-26T11:48:12Z","doi":"10.1145/3218176.3218231","department":[{"_id":"27"},{"_id":"518"},{"_id":"304"}],"project":[{"_id":"32","name":"Performance and Efficiency in HPC with Custom Computing","grant_number":"PL 595/2-1 / 320898746"},{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"publication_identifier":{"isbn":["978-1-4503-5891-0/18/07"]},"external_id":{"arxiv":["1710.10899"]},"place":"New York, NY, USA","title":"A Massively Parallel Algorithm for the Approximate Calculation of Inverse p-th Roots of Large Sparse Matrices"},{"title":"Automated Code Acceleration Targeting Heterogeneous OpenCL Devices","department":[{"_id":"27"},{"_id":"518"}],"publication_identifier":{"isbn":["9781450349826"]},"publication_status":"published","project":[{"_id":"1","name":"SFB 901","grant_number":"160364472"},{"_id":"4","name":"SFB 901 - Project Area C"},{"grant_number":"160364472","name":"SFB 901 - Subproject C2","_id":"14"}],"date_updated":"2023-09-26T11:47:23Z","doi":"10.1145/3178487.3178534","language":[{"iso":"eng"}],"ddc":["000"],"user_id":"15278","file_date_updated":"2018-11-02T14:43:37Z","publication":"Proc.

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.","lang":"eng"}],"date_created":"2018-03-22T11:10:23Z","status":"public","has_accepted_license":"1","file":[{"success":1,"relation":"main_file","content_type":"application/pdf","date_updated":"2018-11-02T15:02:28Z","creator":"ups","file_id":"5291","file_size":230235,"access_level":"closed","file_name":"08056844.pdf","date_created":"2018-11-02T15:02:28Z"}],"publication":"Proc.

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."}],"user_id":"15278","ddc":["040"],"file":[{"file_id":"1560","creator":"florida","file_size":184334,"success":1,"relation":"main_file","content_type":"application/pdf","date_updated":"2018-03-21T13:01:09Z","date_created":"2018-03-21T13:01:09Z","file_name":"138-07740545.pdf","access_level":"closed"}],"file_date_updated":"2018-03-21T13:01:09Z","publication":"Proceedings of International Forum on Research and Technologies for Society and Industry (RTSI)","quality_controlled":"1","author":[{"id":"8961","last_name":"Riebler","full_name":"Riebler, Heinrich","first_name":"Heinrich"},{"full_name":"Vaz, Gavin Francis","first_name":"Gavin Francis","id":"30332","last_name":"Vaz"},{"first_name":"Christian","full_name":"Plessl, Christian","orcid":"0000-0001-5728-9982","last_name":"Plessl","id":"16153"},{"last_name":"Trainiti","first_name":"Ettore M.

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"}],"user_id":"15278","ddc":["040"],"page":"912-917","year":"2016","citation":{"short":"A.

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"}],"date_created":"2017-10-17T12:41:38Z","status":"public","has_accepted_license":"1","publication":"Proceedings of the 2015 Conference on Design, Automation and Test in Europe (DATE)","file_date_updated":"2018-03-21T10:29:49Z","author":[{"last_name":"Damschen","full_name":"Damschen, Marvin","first_name":"Marvin"},{"first_name":"Heinrich","full_name":"Riebler, Heinrich","last_name":"Riebler","id":"8961"},{"id":"30332","last_name":"Vaz","full_name":"Vaz, Gavin Francis","first_name":"Gavin Francis"},{"orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","first_name":"Christian","id":"16153","last_name":"Plessl"}],"publisher":"EDA Consortium / IEEE","quality_controlled":"1","file":[{"content_type":"application/pdf","date_updated":"2018-03-21T10:29:49Z","success":1,"relation":"main_file","file_size":380552,"file_id":"1500","creator":"florida","access_level":"closed","file_name":"238-plessl15_date.pdf","date_created":"2018-03-21T10:29:49Z"}],"_id":"238","page":"1078-1083","citation":{"short":"M.

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":[{"_id":"1","grant_number":"160364472","name":"SFB 901"},{"grant_number":"160364472","name":"SFB 901 - Subprojekt C2","_id":"14"},{"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"}],"title":"Reconstructing AES Key Schedules from Decayed Memory with FPGAs"},{"title":"Runtime Resource Management in Heterogeneous System Architectures: The SAVE Approach","user_id":"15278","project":[{"grant_number":"610996","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","_id":"34"}],"date_created":"2018-03-26T13:40:14Z","status":"public","department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"publication":"Proc.

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.

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.

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."}],"ddc":["040"],"user_id":"15278","language":[{"iso":"eng"}],"date_updated":"2023-09-26T13:36:40Z","doi":"10.1109/ReConFig.2014.7032535","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"},{"_id":"34","grant_number":"610996","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures"}],"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"}],"citation":{"mla":"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."}],"page":"386-389","type":"conference","year":"2013","citation":{"ieee":"H.

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."}]},{"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.

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.

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.","lang":"eng"}],"year":"2012","citation":{"ieee":"M.

Virtualization enables the consolidation of virtual machines as well as the migration of them to other hosts during runtime. Each provider has its own strategy to efficiently operate a data center. We present a rule based mapping algorithm for VMs, which is able to automatically adapt the mapping between VMs and physical hosts. It offers an interface where policies can be defined and combined in a generic way. The algorithm performs the initial mapping at request time as well as a remapping during runtime. It deals with policy and infrastructure changes. We extended the open source IaaS solution Eucalyptus and we evaluated it with typical policies: maximizing the compute performance and VM locality to achieve a high performance and minimizing energy consumption. The evaluation was done on state-of-the-art servers in our own data center and by simulations using a workload of the Parallel Workload Archive. The results show that our algorithm performs well in dynamic data centers environments.","lang":"eng"}],"user_id":"15274","title":"Rule Based Mapping of Virtual Machines in Clouds"},{"citation":{"ieee":"O.

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"],"type":"conference","citation":{"ieee":"M.
