Hello board,

Thanks in advance to anyone who is able to assist us with this problem.
We are running OpenFoam 1.4.1 on a suse 10.3 cluster. Half of our nodes have infiniband installed, half do not. This case appears to work on the non-infiniband nodes but not on the infiniband nodes. Here is the point at which mpirun is erroring out.

[95] Nprocs : 160
[node024][0,1,104][btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_comple te_connect] connect() failed with errno=113
[node020][0,1,72][btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_comple te_connect] connect() failed with errno=113
[node026][0,1,120][btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_comple te_connect] connect() failed with errno=113
[node028][0,1,136][btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_comple te_connect] connect() failed with errno=113
[node009][0,1,8][btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_comple te_connect] connect() failed with errno=113
[node022][0,1,88][btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_comple te_connect] connect() failed with errno=113
[node014][0,1,32][btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_comple te_connect] connect() failed with errno=113
[node030][0,1,152][btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_comple te_connect] connect() failed with errno=113

Does this look familiar to anyone? ANy help will be greatly appreciated.

We had similar messages when we had two ethernet cards per node and had to use the 'mca' parameters to have it use eth0 only:

mpirun --mca btl_tcp_if_exclude lo,eth1 --hostfile {hostfile} -np 4 ...

Don't know about infiniband but you might have to do something similar. See the openmpi documentation.
