Outline of Final Research Achievements

FPGAs are attractive candidate of accelerator device of next generation, because of its high power efficiency. However, FPGA based accelerator requires custom circuit design for each applications. This project choose CFD as the main target, to establish basic technics and methods to: automatically divide a large problem onto multiple FPGAs, and to apply FPGA acceleration on an existing source code by exploiting power of high-level synthesis (HLS) tools with minimal modifications on the source code. Because most HLS tools don't support Fortran (while Fortran is still popular in scientific computing), a Fortran HLS tool had developed in this project, too. The methods and tools are not limited to CFD, but also widely applicable to various area of scientific computation.
