+
+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

+Broken:
+export MPIR_CVAR_CH4_OFI_ENABLE_GPU_PIPELINE=1

+This gives good peformance without requiring 
+--enable-cuda-aware-mpi=no
