Hi, On https://www.open-mpi.org/ I read:
> Full MPI-4.1 standards conformance But on https://docs.open-mpi.org/ I read: > In the Open MPI v5.0.x series, all MPI-3.1 functionality is supported. *> Some* MPI-4.0 functionality is supported. > As such, MPI_VERSION is set to 3 and MPI_SUBVERSION is set to 1. By compiling ompi master or 5.0, I indeed get MPI_VERSION to 3. Is https://www.open-mpi.org/ wrong ?
