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`_. .. _AC922: https://www.ibm.com/products/power-systems-ac922/ .. _PGI: https://www.pgroup.com/index.htm .. _Summit: https://www.olcf.ornl.gov/summit/ .. _`WRF/MPAS support forum`: https://forum.mmm.ucar.edu/forums/gpu-openacc.128/
