You are right - the ranks are fine, and local rank doesn't matter. It sounds like a problem where the TCP messaging is getting a message ack'd from someone other than the process that was supposed to recv the message. This should cause us to abort, but we were just talking on the phone that the abort procedure may not be working correctly. Or it could be (as Jeff suggests) that the version mismatch is also preventing us from properly aborting too.

So I fear we are back to trying to find these other versions on your nodes...

Well, the old version is still on the nodes (in /usr/lib as default for OS X)...  

I can try and clean those all out by hand but I'm still confused why the old version would be used - how does openMPI find the right library?  

Note again, that I get these MCA warnings on the server when just running ompi_info and I *have* cleaned out /usr/lib on the server.  So I really don't understand how on the server I can still have a library issue.  Is there a way to trace at runtime what library an executable is dynamically linking to?  Can I rebuild openmpi statically?

Thanks,  Jody

The reason your job is hanging is sitting in the orte-ps output. You have multiple processes declaring themselves to be the same MPI rank. That definitely won't work.

Its the "local rank" if that makes any difference...

Any thoughts on this output?


[xserve03.local][[61029,1],4][btl_tcp_endpoint.c:486:mca_btl_tcp_endpoint_recv_connect_ack] received unexpected process identifier [[61029,1],3]

The question is why is that happening? We use Torque all the time, so we know that the basic support is correct. It -could- be related to lib confusion, but I can't tell for sure.

Just to be clear, this is not going through torque at this point.  Its just vanilla ssh, for which this code worked with 1.1.5.



Can you rebuild OMPI with --enable-debug, and rerun the job with the following added to your cmd line?

-mca plm_base_verbose 5 --debug-daemons -mca odls_base_verbose 5

Working on this...

Thanks,  Jody
