[BUG/ISSUE] Crash when using Intel MPI with certain fabric providers

[WilliamDowns]

As of Intel MPI 2019 Update 8 and libfabric 1.10.0, there is a bug related to registering memory that causes a crash in GCHP when using certain fabric providers. This was originally identified as an issue when using the EFA provider on AWS EC2, but has also been encountered on systems that use the Verbs provider. This issue may be fixed in libfabric 1.11.0. For users who cannot update the libfabric version on their system, a temporary solution is to put the line export MPIR_CVAR_CH4_OFI_ENABLE_RMA=0 in gchp.env. This bug is not relevant to users of other MPI providers such as OpenMPI.
