MarsSeed [1] filed a deletion request for intel-oneapi-mpi [2]: Arch [extra] intel-oneapi-basekit contains the latest version of this library. The Arch package itself does not declare intel-oneapi-mpi in its provides field, but still, it carries all the same mpi files in the following directory: 'opt/intel/oneapi/mpi/' Currently I see no package that specifically depends on 'intel-oneapi- mpi'. If one were to emerge in the future, the maintainers of [extra]/intel- oneapi-basekit could be asked to add a corresponding provides field.
