SPERR Hackathon

On Feb 21, 2023, members from ASAP group and VAST group will attend OpenACC GPU Hackathons to optimize VAST’s SPERR data compressor with GPUs. OpenACC GPU Hackathons are 5-day events designed to help teams of three to six developers accelerate their own codes on GPUs with OpenACC or other tools. SPERR is a C++ library that supports lossy compression of multi-dimensional (one, two, or three) floating-point data. Recent profiling results of SPERR on CPU indicates that of the five most expensive functions, four of them are written in such a way that exposes sufficient parallelism. So in the Hackathons, we are looking for software engineering support to help identify and optimize SPERR to fully utilize GPU performance.
