[ewg] OFED-1.5rc1 with OpenMPI and IB

[Stefan Kuhne]

Hello,

i try to install a small HPC-cluster for education usage.
Infiniband is working as well i can ping over IB.
When i try to run an MPI program i get:

user at head:~/Cluster/hello$ mpirun --hostfile ../Cluster.hosts hello
--------------------------------------------------------------------------
WARNING: There was an error initializing an OpenFabrics device.

   Local host:   head
   Local device: mthca0
--------------------------------------------------------------------------
Hier ist Job  0 von  1 auf head
user at head:~/Cluster/hello$

How can i get more information about this error?

Regards,
Stefan Kuhne
