I'll give an overview of the work done by the Interagency Council for
Advancing Meteorological Services (ICAMS) High Performance Computing
Implementation Team (HPC-IT). The HPC-IT team includes members from 6
different US agencies and meets monthly to discuss HPC related issues.
Over the past two years, HPC-IT team has been assessing the Exascale
and GPU readiness of the major US global weather and climate models.
Most agencies have plans to make use of GPU based supercomputers, but
this has required major investments in new programming models and
associated code refactoring or rewriting. I'll describe the key
points of the HPC-IT team's upcoming readiness report, including the
programming model approaches being considered as well as results
documenting performance improvements made possible by GPUs for global
atmospheric models and performance on exascale systems at cloud
permitting resolutions.
