Abstract:

3D FFTs are used to accelerate MD electrostatic forces computations but are difficult to parallelize due to communications requirements. We present a distributed OpenCL 3D FFT implementation on Intel Stratix 10 FPGAs for grids up to {\boldmath $128^3$}. We use FPGA hardware features such as HBM2 memory and multiple 100 Gbps links to pro...More
