Build / test UFS WM with Intel oneAPI v2024.2.1 (LLVM)-based stacks

[rickgrubin-noaa]

Description

Build and test UFS WM against spack-stack@release/1.8.0 built with Intel oneAPI v2024.2.1 (LLVM) compilers.

Intel oneAPI v2024.2.1 is the last oneAPI release to provide two FORTRAN compilers: ifx (new) and ifort (old / primary compiler in previous releases).

Build and test against stacks built with ifx and ifort, respectively.

Solution

stack environments

hera: /scratch1/NCEPDEV/nems/role.epic/spack-stack/spack-stack-1.8.0-llvm/envs

• ifx

  • ue-llvm-ifx-2024.2.1
  • gsi-llvm-ifx-2024.2.1

• ifort

  • ue-llvm-ifort-2024.2.1
  • gsi-llvm-ifort-2024.2.1

Will also require addon environments for each compiler for a known-to-work combination of MAPL / ESMF.

Once the MAPL / ESMF addon envs are ready, steps to load required modules, e.g. for the ifx compiler:

module purge
module use /scratch1/NCEPDEV/nems/role.epic/spack-stack/spack-stack-1.8.0-llvm/envs/ue-llvm-ifx-2024.2.1/install/modulefiles/Core
module load stack-oneapi/2024.2.1
module load stack-intel-oneapi-mpi/2021.13
module load ufs-weather-model-env/1.0.0
module load geos-gcm-env/1.0.0
