Supported platforms

At present, the GPU-enabled MPAS-Atmosphere code is only supported on IBM’s AC922 architecture with the 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 support forum.
