We describe an experimental system for parallel distributed processing of numerical algorithms. Computations are performed on GPUs, and communication is facilitated using FPGA-adapters and self-developed interconnects. As case study we have implemented a conjugate gradient solver for the Poisson problem in three dimensions. The work focuses on machine architecture and distributed processing with special...
An element-by-element preconditioned conjugate gradient (PCG) iterative solver for the solution of 3D finite element analysis has been implemented into a FPGA-based 32-bit floating-point reconfigurable computer. The algorithm formulation has been chosen in order to optimize the match with the capabilities of the FPGA platform. It is capable of giving a speed-up of about 40 times compared to an optimized...
