Changing HPC architecture and software stack create enormous challenges for HPC application developers that need to write performance portable code and keep existing applications up to speed. Purely manual solutions are cost prohibitive. Source-to-source translators are poised to address these challenges automatically or with user input semi-automatically. Practical compiler-enabled programming environments, applied analysis methodologies, and end-to-end toolchains are crucial to performance portability in the exascale era. C3PO is a new workshop at the intersection of compilers/translators, HPC middleware, and HPC applications. The workshop brings together researchers with a shared interest in applying compilation and source-to-source translation methodologies to enhance parallel programming, including explicit programming models such as MPI, OpenMP, and hybrid models.
