Hi,

I'm trying to set up a new small cluster. It's based on Sun's X4100
servers running Solaris 10_x86. I have Open MPI that comes within
Clustertools 7. In addition, I have an Infiniband network between
the nodes. I can run parallel jobs fine if processes remain on one
node (each node has 4 cores). However, as soon as I try to run across
the nodes I get these errors from the job:

[node3][0,1,8][/ws/hpc-ct-7/builds/7.0.build-ct7-030/ompi-ct7/ompi/mca/btl/udapl/btl_udapl_component.c:827:mca_btl_udapl_component_progress]
WARNING : Connection event not handled : 16391

I've had a good look through the archives but can't find a reference
to this error. I realise the udapl interface is a sun addition to
OpenMPI but I'm hoping someone else will have seen this before and
know what's wrong. I have checked my IB network is functioning
correctly (seemed the obvious thing that could be wrong).

Any pointers on what could be wrong much appreciated.

ifconfig for the IB port reports:

$ ifconfig ibd1
ibd1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 2044 index 3
         inet 192.168.50.200 netmask ffffff00 broadcast 192.168.50.255

.. and for the other configured interface:

$ ifconfig e1000g0
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
         inet 192.168.47.190 netmask ffffff00 broadcast 192.168.47.255
