Add support for Intel LLVM-based compilers

uturuncoglu commented 3 months ago

Description

I was experimenting UFS Weather Model under TACC Frontera as a part of UFS coastal project. I could able to run model configurations using spack-stack 1.5.1 along with intel/19.1.1 and impi/19.0.9 but when I try to upgrade the compiler and MPI to their newer versions (intel/23.1.0 and impi/21.9.0 - intel-oneapi), I started to get following error,

CMake Error at CMakeLists.txt:149 (include):
  include could not find requested file:

    cmake/IntelLLVM.cmake

I think that the reason is the Intel compiler. In my case, ${CMAKE_Fortran_COMPILER_ID} is returning IntelLLVM and model build is failing since there is no cmake/IntelLLVM.cmake (https://github.com/ufs-community/ufs-weather-model/blob/8e7b61b197f777328464eb2e7dbd006c6c148829/CMakeLists.txt#L139). I am seeing usage of IntelLLVM along with Intel in some places of the code but it is not a standard and used in everywhere.

Solution

I think, the top level CMake file as well as CMake interfaces of the components needs to be extended to allow IntelLLVM.

Alternatives

Not sure

@DusanJovic-NOAA Thanks. I was not aware of it. Do you want me to close this issue? or you prefer to keep it open.

Keep it open. We can use this issue to track the progress.
