Hi Michka,
Which libfabric version are you using? Could you try setting `MPIR_CVAR_CH4_OFI_CAPABILITY_SETS_DEBUG=` to see if there is more debug messages?

Hi
Homebrew maintainer here (https://github.com/Homebrew <https://github.com/Homebrew>). Homebrew ships mpich as a package on both MacOS and Linux.
The issue below was found with version 3.4.1 but might have been there for longer.
We noticed that mpich was building it’s own internal libfabric dependency. After reading https://lists.mpich.org/pipermail/discuss/2021-January/006092.html <https://lists.mpich.org/pipermail/discuss/2021-January/006092.html>, we added `--with-device=ch4:ofi` and set the libfabric path with the --with-libfabric= flag, to use our own version.
The build is fine. We have a small test to check if mpich is still working fine;
#include <mpi.h> #include <stdio.h> int main() { int size, rank, nameLen; char name[MPI_MAX_PROCESSOR_NAME]; MPI_Init(NULL, NULL); MPI_Comm_size(MPI_COMM_WORLD, &size); MPI_Comm_rank(MPI_COMM_WORLD, &rank); MPI_Get_processor_name(name, &nameLen); printf("[%d/%d] Hello, world! My name is %s.\\n", rank, size, name); MPI_Finalize(); return 0; }
Executing the test fails with a weird error:
/usr/local/Cellar/mpich/3.4.1_2/bin/mpicc hello.c -o hello ./hello Abort(1615247) on node 0 (rank 0 in comm 0): Fatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(152).......: MPID_Init(597)..............: MPIDI_OFI_mpi_init_hook(674): create_vni_context(964).....: OFI resource bind failed (ofi_init.c:964:create_vni_context:No message available on STREAM) [unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=1615247 : system msg for write_line failure : Bad file descriptor Abort(1615247) on node 0 (rank 0 in comm 0): Fatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(152).......: MPID_Init(597)..............: MPIDI_OFI_mpi_init_hook(674): create_vni_context(964).....: OFI resource bind failed (ofi_init.c:964:create_vni_context:No message available on STREAM) [unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=1615247 : system msg for write_line failure : Bad file descriptor
This test passes fine on Linux, and fails only on MacOS. Using the internal libfabric is fine on both platforms.
Here is the related discussion: https://github.com/Homebrew/homebrew-core/pull/73062 <https://github.com/Homebrew/homebrew-core/pull/73062>
Maybe you could help us debug this issue?
