Hello all! When I try to run an application with 512 cores (or more) I get this MPI error:  MPI startup(): ofa fabric is not available and fallback fabric is not enabled
I'm usingI_MPI_FABRICS=shm:ofa, but with DAPL I also get an MPI error. Using 256 cores or less I got no errors, it works like a charm. The system is a SGI cluster with quad-socket AMD Interlagos nodes (64 cores per node). Each node as two Infiniband ports and theI_MPI_OFA_NUM_PORTS=2 is enabled. Thank you in advance!
