HI! I trying run parallel "Hello, World!" program using OpenMPI on cluster. My program written on C++ and compiled with this OpenMPI soft (mpicxx). Cluster uses InfiniBand and TCP networks. I install OpenMPI soft in my home directory on manager node. After this I get to the node via SSH (ssh node54, for example) and run my program by command:
$openmpiBinFolder/mpirun -np 1 prog
But next error occured:
--------------------------------------------------------------------------
Failed to create a queue pair (QP):
Hostname: node73
Requested max number of outstanding WRs in the SQ: 1
Requested max number of outstanding WRs in the RQ: 2
Requested max number of SGEs in a WR in the SQ: 4096
Requested max number of SGEs in a WR in the RQ: 4096
Requested max number of data that can be posted inline to the SQ: 0

Open MPI has detected that there are UD-capable Verbs devices on your
system, but none of them were able to be setup properly. This may
indicate a problem on this system.
You job will continue, but Open MPI will ignore the "ud" oob component
in this run.
Hostname: node73
--------------------------------------------------------------------------
How I can fix it? What does this error mean?
ompi_info command output in application.
ompi_info.out.bz2
