---enable-cuda-aware-mpi=no  
---enable-unified=no
-
-Grid's internal D-H-H-D pipeline mode, avoid device memory in MPI
-Do not use SVM
-
-Ideally use MPICH with fix to issue 7302:
-
-https://github.com/pmodels/mpich/pull/7312
-
-Ideally:
-MPIR_CVAR_CH4_IPC_GPU_HANDLE_CACHE=generic
-
-Alternatives:
-export MPIR_CVAR_NOLOCAL=1
-export MPIR_CVAR_CH4_IPC_GPU_P2P_THRESHOLD=1000000000
-
---------------------------------------------------------------------
-MPICH/Aurora/PVC correctness and performance 
---------------------------------------------------------------------
-
-Broken:
-export MPIR_CVAR_CH4_OFI_ENABLE_GPU_PIPELINE=1
-
-This gives good peformance without requiring 
---enable-cuda-aware-mpi=no  
-
-But is an open issue reported by James Osborn
-https://github.com/pmodels/mpich/issues/7139
-
-Possibly resolved but unclear if in the installed software yet.
