GPU-enabled MPAS Supported Platforms

The GPU-enabled MPAS-Atmosphere code is only supported on IBM’s AC922 architecture with PGI compilers.

Most testing and development has taken place on the ORNL Summit machine with the following compilers and libraries:

• PGI 19.10 compilers

• zlib 1.2.11

• HDF5 1.10.5

• PnetCDF 1.12.1

• netCDF-C 4.6.3

• netCDF-Fortran 4.5.2

• PIO 2.4.4

If you have had success in porting the code to another platform, we encourage you to let us know with a post to the MPAS-Atmosphere -> GPU/OpenACC section of the WRF & MPAS-A User Support Forum.
