Regression Test Policy for Weather Model Platforms and Compilers

Gillian Petro edited this page Sep 26, 2024 · 32 revisions

The regression test policy for the UFS Weather Model (WM) follows the general principles outlined in the Regression Test Policy for UFS Platforms and Compilers. The details for the UFS Weather Model are outlined below.

Currently, the UFS WM supports the Tier-1 platforms listed below. Although plans are under consideration for adding Gaea C6, Ursa, and Rhea, these platforms are not yet supported for the UFS WM.

Tier-1 platforms

Platform Responsibility for tests Test coverage Status
NOAA WCOSS2 with default Intel 19 software stack EMC EMC-PROD tests (rt.conf) Implemented
NOAA RDHPC Hera with default Intel 2022 software stack EPIC/EMC EMC-PROD tests (rt.conf) Implemented

NOAA RDHPC Jet with default Intel 2022 software stack EPIC/EMC EMC-PROD tests (rt.conf) Implemented
MSU Orion with default Intel 2022 software stack EPIC/EMC EPIC/EMC-PROD tests (rt.conf) Implemented
NCAR CISL Derecho with default Intel 2021.10.0 software stack EPIC/EMC EMC-PROD tests (rt.conf) Implemented

Tier-2 platforms

Platform Responsibility for tests Test coverage Status
Linux platforms with GNU 9.1.0 compiler and MPICH 3.3.1 MPI library (cloud platforms?) TBD TBD Implemented
Linux platforms with Intel 19 compiler and MVAPICH2 2.3.2 MPI library (cloud platforms?) TBD TBD Implemented
macOS platforms with LLVM clang 9.x.y + GNU gfortran 9.m.n compiler and mpich 3.r.s MPI library TBD TBD Implemented
macOS platforms with GNU gcc+gfortran 9.x.y and mpich 3.r.s MPI library TBD TBD Implemented

Tier-3 platforms

  • Linux platforms with other combinations and/or other versions of the Intel or GNU compiler and MPI libraries than those listed above.
  • NAG compiler.
  • clang/flang compiler: currently an open source development, the flang compiler is designed as a Fortran front-end for the LLVM clang compiler and may provide an interesting alternative in the future if/once matured (see this link for more information)
