Enabling Libfabric Support
By default, the script that sets the environmental variables (
) sets the environment to libfabric shipped with the Intel MPI Library.
To disable this, use the
environment variable or the
option passed to the script:
# Do not set the environment to libfabric from the Intel MPI Library.
> call <install-dir>\env\vars.bat -i_mpi_ofi_internal=0
# Set the environment to libfabric from the Intel MPI Library.
> call <install-dir>\env\vars.bat -i_mpi_ofi_internal=1
environment variable to 1 before running an MPI application to see the libfabric version and provider.
