@inbook{56606, abstract = {{AbstractMost FPGA boards in the HPC domain are well-suited for parallel scaling because of the direct integration of versatile and high-throughput network ports. However, the utilization of their network capabilities is often challenging and error-prone because the whole network stack and communication patterns have to be implemented and managed on the FPGAs. Also, this approach conceptually involves a trade-off between the performance potential of improved communication and the impact of resource consumption for communication infrastructure, since the utilized resources on the FPGAs could otherwise be used for computations. In this work, we investigate this trade-off, firstly, by using synthetic benchmarks to evaluate the different configuration options of the communication framework ACCL and their impact on communication latency and throughput. Finally, we use our findings to implement a shallow water simulation whose scalability heavily depends on low-latency communication. With a suitable configuration of ACCL, good scaling behavior can be shown to all 48 FPGAs installed in the system. Overall, the results show that the availability of inter-FPGA communication frameworks as well as the configurability of framework and network stack are crucial to achieve the best application performance with low latency communication.}}, author = {{Meyer, Marius and Kenter, Tobias and Petrica, Lucian and O’Brien, Kenneth and Blott, Michaela and Plessl, Christian}}, booktitle = {{Lecture Notes in Computer Science}}, isbn = {{9783031697654}}, issn = {{0302-9743}}, publisher = {{Springer Nature Switzerland}}, title = {{{Optimizing Communication for Latency Sensitive HPC Applications on up to 48 FPGAs Using ACCL}}}, doi = {{10.1007/978-3-031-69766-1_9}}, year = {{2024}}, } @inproceedings{56158, author = {{Gil, Oliver Fernández and Patrizi, Fabio and Perelli, Giuseppe and Turhan, Anni-Yasmin}}, booktitle = {{Proceedings of the 37th International Workshop on Description Logics (DL 2024), Bergen, Norway, June 18-21, 2024}}, editor = {{Giordano, Laura and Jung, Jean Christoph and Ozaki, Ana}}, publisher = {{CEUR-WS.org}}, title = {{{Optimal Alignment of Temporal Knowledge Bases (Extended Abstract)}}}, volume = {{3739}}, year = {{2024}}, } @inproceedings{56605, author = {{Opdenhövel, Jan-Oliver and Alt, Christoph and Plessl, Christian and Kenter, Tobias}}, booktitle = {{2024 34th International Conference on Field-Programmable Logic and Applications (FPL)}}, publisher = {{IEEE}}, title = {{{StencilStream: A SYCL-based Stencil Simulation Framework Targeting FPGAs}}}, doi = {{10.1109/fpl64840.2024.00023}}, year = {{2024}}, } @inproceedings{56607, author = {{Tareen, Abdul Rehman and Meyer, Marius and Plessl, Christian and Kenter, Tobias}}, booktitle = {{2024 IEEE 32nd Annual International Symposium on Field-Programmable Custom Computing Machines (FCCM)}}, publisher = {{IEEE}}, title = {{{HiHiSpMV: Sparse Matrix Vector Multiplication with Hierarchical Row Reductions on FPGAs with High Bandwidth Memory}}}, doi = {{10.1109/fccm60383.2024.00014}}, volume = {{35}}, year = {{2024}}, } @article{56270, author = {{Grauthoff, Fabian and Meyer-Hamme, Johannes and Imoullas, Mohamed Nassim}}, journal = {{Geschichte Lernen}}, number = {{221}}, publisher = {{Friedrich}}, title = {{{„...und warum soll das relevant sein?"

The intensive computation and bandwidth demand for ERI evaluation presents a significant challenge for quantum-mechanics-based atomistic simulations with hybrid density functional theory: due to the tens of trillions of ERI computations in each time step, practical applications are usually limited to thousands of atoms. In this work, we propose SERI, a high-throughput streaming accelerator for ERI computation on HBM-based FPGAs. In contrast to prior buffer-based designs, SERI proposes a novel streaming architecture to address the on-chip buffer limitation and the floorplanning challenge, and leverages the high-bandwidth memory to overcome the bandwidth bottleneck in prior designs. Moreover, to meet the varying computation, bandwidth, and floorplanning requirements between the 55 canonical quartet classes in ERI calculation, we design an automation tool, together with an accurate performance model, to automatically customize the architecture and floorplanning strategy for each canonical quartet class to maximize their throughput. Our performance evaluation on the AMD/Xilinx Alveo U280 FPGA board shows that, SERI achieves an average speedup of 9.80 x over the previous best-performing FPGA design, a 3.21x speedup over a 64-core AMD EPYC 7713 CPU, and a 15.64x speedup over an Nvidia A40 GPU. It reaches a peak throughput of 23.8 GERIS ($10^9$ ERIs per second) on one Alveo U280 FPGA.

This study presents a novel approach to prevent expulsion by employing a preheating current. Through characteristic analysis of joint formation under critical welding current, the importance of plastic material encapsulation around the weld nugget (plastic shell) at high temperatures in preventing expulsion is highlighted. To evaluate the effect of preheating on the plastic shell and understand its mechanism in expulsion prevention, a two-dimensional welding simulation model for dissimilar ultra-high strength steel joints was established. The results showed that optimal preheating enhances the thickness of the plastic shell, improving its ability to encapsulate the weld nugget during the primary welding phase, thereby diminishing expulsion risks. Experimental validation confirmed that by employing the optimal preheating current, the maximum nugget diameter was enhanced to 9.42 mm, marking an increase of 13.4 % and extending the weldable current range by 27.5 %. Under quasi-static cross-tensile loading, joints with preheating demonstrated a 7.9 % enhancement in maximum load-bearing capacity compared to joints without preheating, showing a reproducible and complete pull-out failure mode within the heat-affected zone.
