TY - CHAP A1 - Mayer, Florian A1 - Knaust, Marius A1 - Philippsen, Michael T1 - OpenMP on FPGAs—A Survey T2 - OpenMP: Conquering the Full Hardware Spectrum N2 - Due to the ubiquity of OpenMP and the rise of FPGA-based accelerators in the HPC world, several research groups have attempted to bring the two together by building OpenMP-to-FPGA compilers. This paper is a survey of the current state of the art (with a focus on the OpenMP target pragma). It first introduces and explains a design space for the compilers. Design space dimensions include how FPGA infrastructure is generated, how work is distributed, and where/how target outlining is done. A table concisely condenses the available information on the surveyed projects which are also summarized and compared. The paper concludes with possible future research directions.
