| Abstract(in English) | Due to the advantages of multiple FPGAs as accelerators for High Performance Computing, AiS is receiving increased attention as a system. AiS has application-specific system in the low-latency communication-enhanced interconnect between each FPGA, and which suggests improvement of the performance. In Center for Computational Sciences in University of Tsukuba, ARGOT (Accelerated Radiative transfer on Grids using Oct-Tree) is developed as simulation code for cosmic radiative transfer. This application are investigating to apply to the AiS for the sake of increase performance of the simulation. The suggestion of this study is FPGA-based acceleration for ART(Authentic Radiation Transfer) scheme in the ARGOT. FPGAs will solve a control for the random-like access caused by what ART uses the three-dimensional mesh grids. However, it is difficult to store a huge amount of mesh data generated when the calculation is done only to On-chip Memory in FPGAs, which was a cause of performance degradation. To improve the performance, this paper suggests the implementation of the ART scheme with HBM (High Bandwidth Memory). At first, the discussion about memory access performance for HBM and Xilinx HBM subsystem on Xilinx Alveo U280. Subsequently, intending to utilize On-chip RAM (BRAM・URAM) as SPM (Scratchpad Memory) when reading mesh data from HBM, we discuss the access rate to SPM where the memory access is not a bottleneck and the suggestion for decreasing the number of accesses to Off-chip memory. |
