Re: [OMPI devel] MPI_Comm_spawn under Torque

Thanks Ralph! I must have mentioned though. Without the Torque environment, spawning with ssh works ok. But Under the torque environment, not. I started the simple_spawn with 3 processes and spawned 9 processes (3 per node on 3 nodes). There is no problem with the Torque environment because

Re: [OMPI devel] MPI_Comm_spawn under Torque

Hmmm...I don't see anything immediately glaring. What do you mean by "doesn't work"? Is there some specific behavior you see? You might try the attached program. It's a simple spawn test we use - 1.7.4 seems happy with it. simple_spawn.c Description: Binary data On Feb 20, 2014, at 10:14

[OMPI devel] MPI_Comm_spawn under Torque

Hello! I am having problem using MPI_Comm_spawn under torque. It doesn't work when spawning more than 12 processes on various nodes. To be more precise, "sometimes" it works, and "sometimes" it doesn't! Here is my case. I obtain 5 nodes, 3 cores per node and my $PBS_NODEFILE looks like below.

Yes, I've added them to my Cisco MTT ini files in the ompi-svn repo. Look in cisco/mtt/usnic/usnic-trunk.ini and usnic-v1.7.ini. All relevant sections have "oshmem" in them. Most are copied from the Mellanox examples, but I made a few tweaks/improvements here and there. I also anticipate

[OMPI devel] oshmem test suite errors

For all of these, I'm using the openshmem test suite that is now committed to the ompi-svn SVN repo. I don't know if the errors are with the tests or with oshmem itself. 1. I'm running the oshmem test suite at 32 processes across 2 16-core servers. I'm seeing a segv in

[OMPI devel] oshmem tests

I took the liberty of committing the openshmem test suite 1.0d to the ompi-tests SVN, mainly because there are some post-release patches that are necessary to get it to compile/run properly. Mellanox put some clever workarounds in the MTT ini file for a first round of patches, but I'm finding

[OMPI devel] udcm_component_query hangs when memlock not infinite

Hello, We're setting up a new cluster here. Open MPI 1.7.4 was hanging at startup without any error message. The issue appears to be udcm_component_query() hanging in finalize() on the sched_yield() loop when memlock limit isn't set to unlimited as usual. Unfortunately the hangs occur before we
