Feasibility Study of Porting a Particle Transport Code to FPGA

摘要

In this paper we discuss porting a particle transport code, which is based on a wavefront sweep algorithm, to FPGA. The original code is written in Fortran90. We describe the key differences between general purpose CPUs and Field Programmable Gate Arrays (FPGAs) and provide a detailed performance model of the FPGA. We describe the steps we took when porting the Fortran90 code to FPGA. Finally, the paper will present results from an extensive benchmarking exercise using a Virtex 6 FPGA.
