Re: [OMPI users] exited on signal 11 (Segmentation fault).

Hi Mouhamad Stack of 10240kB is probably the Linux default, not necessarily good for HPC and number crunching. I'd suggest that you change it to unlimited, unless your system administrator has a very good reason not to do so. We've seen many atmosphre/ocean/climate models crash because they could

Re: [OMPI users] Checkpoint from inside MPI program with OpenMPI 1.4.2 ?

Since this would be a new feature for 1.4, we cannot move it since the 1.4 branch is for bug fixes only. However, we may be able to add it to 1.5. I filed a ticket if you want to track that progress: https://svn.open-mpi.org/trac/ompi/ticket/2895 -- Josh On Tue, Oct 25, 2011 at 11:52 PM, Nguye

[OMPI users] Changing plm_rsh_agent system wide

I need to change system wide how OpenMPI launch the jobs on the nodes of my cluster. Setting: export OMPI_MCA_plm_rsh_agent=oarsh works fine but I would like this config to be the default with OpenMPI. I've read several threads (discussions, FAQ) about this but none of the provided solutions

Re: [OMPI users] Checkpoint from inside MPI program with OpenMPI 1.4.2 ?

Dear Josh, Thank you. I will test the 1.7 trunk as you suggested. Also I want to ask if we can add this interface to OpenMPI 1.4.2, because my applications are mainly involved in this version. Regards, Nguyen Toan On Wed, Oct 26, 2011 at 3:25 AM, Josh Hursey wrote: > Open MPI (trunk/1.7 - not
