Did you run it with -mca mpi_paffinity_alone 1? Given this is 1.4.1, you can
set the bindings to -bind-to-socket or -bind-to-core. Either will give you
improved performance.
IIRC, MVAPICH defaults to -bind-to-socket. OMPI defaults to no binding.

Hello again,
Hopefully this is an easier question
My cluster uses Infiniband interconnects (Mellanox Infinihost III and some
ConnectX). I'm seeing terrible and sporadic latency (order ~1000 microseconds)
as measured by the subounce code (http://sourceforge.net/projects/subounce/),
but th
Could you please ask them about this:
OMPI makes the following call to connect to the mother superior:
struct tm_roots tm_root;
ret = tm_init(NULL, &tm_root);
Could they tell us why this segfaults in PBS Pro? It works correctly with all
releases of Torque.
Thanks
Ralph

Well,
We all wish the Altair guys would at least try to maintain backwards
compatibility with the community, but they have a big habit of
breaking things. This isn't the first time they've broken a more
customer facing function like tm_spawn. (The also like breaking
pbs_statjob too!).
Bummer!
If it helps, could you put us in touch with the PBS Pro people? We usually
only have access to Torque when developing the TM-launching stuff (PBS Pro and
Torque supposedly share the same TM interface, but we don't have access to PBS
Pro, so we don't know if it has diverged over time).
Ralph,
This is my first build of OpenMPI so I haven't had this working before. I'm
pretty confident that PATH and LD_LIBRARY_PATH issues are not the cause,
otherwise launches outside of PBS would fail too. Also, I tried compiling
everything statically with the same result.
Some additional in
