OpenMP for GPUs on NERSC-9
Abstract:

OpenMP has a 20 year history in HPC, and been used by NERSC developers for node-level parallelization on several generations of NERSC flagship systems. Recent versions of the OpenMP specification include features that enable Accelerator programming generally, and GPU programming in particular. Given the extensive use of OpenMP on previous NERSC systems, and the GPU-based node architecture of NERSC-9, we expect OpenMP to be important in helping users migrate applications to NERSC-9. In this talk we'll give an overview of the current usage of OpenMP at NERSC, describe some of the new features we think will be important to NERSC-9 users, and give a high-level overview of a collaboration between NERSC and NVIDIA to enable OpenMP for GPUs in the PGI Fortran, C and C++ compilers.
