Re: [OMPI users] OpenMPI with SGE: "-np N" for mpirun needed?

Dear all, is "-np N" parameter needed for mpirun when running jobs under SGE environment? All examples in http://www.open-mpi.org/faq/?category=running#run-n1ge-or-sge show that "-np N" is used, but in my opinion it should be redundant: mpirun should determine all parameters from SGE

As a follow up, the problem was with host name resolution. The error was introduced, with a change to the Rocks environment, which broke reverse lookups for host names. -- Ray Muno

We are running a cluster using Rocks 5.0 and OpenMPI 1.2 (primarily). Scheduling is done through SGE. MPI communication is over InfiniBand. We have been running with this setup for over 9 months. Last week, all user jobs stopped executing (cluster load dropped to zero). User can schedule jobs

Re: [OMPI users] Openmpi with SGE

I am not quite sure. It seems that your AR (advance reservation) snapshot3 build is a bit new, and it may be a problem coming from it. I am not quite familiar with this new SGE feature. I'd ping the gridengine list to check on that error message coming from execd. Neeraj Chourasia wrote:
