After install MIC on compute node, i had problem with MPI.
I use CentOS 6.7 + OFED 3.18.1 with MIC support.
With same options in /etc/modprobe.d/ibscif.conf, i had:
-if options ibscif new_ib_type=1:
transport: invalid transport (-1)
-if options ibscif new_ib_type=0, transport is OK, but in both cases don't work StarCCM+, because it try to use scif as RDMA (because as first RDMA device set scif, "starccm+: Rank 0:6: MPI_Init: rdma_accept() failed").
I set options ibscif enable_fast_rdma=1, it's remove scif device from RDMA devices list and StarCCM+ works.
But I don't understand - this "fast RDMA" mode is good for MIC's?
