Hi,
I built OpenMPI 1.8.3 using PGI 14.7 and enabled CUDA support for CUDA 6.0. I
have a Fortran test code that tests GPUDirect and have included it here. When
I run it across 2 nodes using 4 MPI procs, sometimes it fails with incorrect
results. Specifically, sometimes rank 1 does not receiv
Direct RDMA. However, to eliminate it, you could run with:
--mca btl_openib_want_cuda_gdr 0.
