Prentice, Ooh. The first one seems to work. The second one apparently is not liked by zsh and I had to do: ❯ mpirun -mca btl '^tcp' -np 6 ./helloWorld.mpi3.exe Compiler Version: GCC version 10.2.0 MPI Version: 3.1 MPI Library Version: Open MPI v4.1.0, package: Open MPI mathomp4@gs6101-parcel.local Distribution, ident: 4.1.0, repo rev: v4.1.0, Dec 18, 2020
Next question: is this: OMPI_MCA_btl='self,vader' the right environment variable translation of that command-line option?
