Really? I thought we only took OpenFabrics device names in the
openib_if_include MCA param...? It looks like ib0.8109 is an IPoIB
device name.

Hi,
I'm trying to get openmpi working over openib partitions. On this
cluster, the partition number is 0x109. The ib interfaces are
pingable over the appropriate ib0.8109 interface:
d2:/opt/openmpi-ib # ifconfig ib0.8109
ib0.8109 Link encap:UNSPEC HWaddr 80-00-00-4A-
FE-80-00-00-00-00-00-00-00-00-00-00

I have tried the following:
/opt/openmpi-ib/1.2.6/bin/mpirun -np 2 -machinefile machinefile -mca
btl openib,self -mca btl_openib_max_btls 1 -mca
btl_openib_ib_pkey_val 0x8109 -mca btl_openib_ib_pkey_ix 1 /cluster/
pallas/x86_64-ib/IMB-MPI1
but I just get a RETRY EXCEEDED ERROR. Is there a MCA parameter I am
missing?
I was successful using tcp only:
/opt/openmpi-ib/1.2.6/bin/mpirun -np 2 -machinefile machinefile -mca
btl tcp,self -mca btl_openib_max_btls 1 -mca btl_openib_ib_pkey_val
0x8109 /cluster/pallas/x86_64-ib/IMB-MPI1
Thanks,
Matt Burgess
