Re: [OMPI users] WRF run on multiple Nodes
Did you request an allocation from PCM? If not, then PCM will block you from arbitrarily launching jobs on non-allocated nodes. Print out your environment and look for any envars from PCM and/or LSF (e.g., LSB_JOBID). I don't know what you mean about "no OMPI application is yet integrated with LSF" - an application would never be integrated with LSF. However, OMPI will configure itself to use LSF as its launcher if it detects the presence of LSF on the system. When that happens, you no longer need to supply a machinefile as OMPI will automatically pickup the list of allocated nodes.

Re: [OMPI users] WRF run on multiple Nodes
Dear John Hearns, The cluster is installed using Platform cluster Manager (PCM). LSF is installed but no OpenMPI application is yet integrated with LSF. WRF help gave me following instructions. mpirun -v -machinefile ~/mach.conf -np 2 wrf.exe Please talk to your computer manager about how to setup mach.conf and allow communications between nodes. Ahsan, you have a Dell cluster. Can we ask which company installed the cluster, and who manages the cluster? The company who installed it should have given you some documentation on how to run MPI jobs. Also can we ask if there is a batch scheduler or workload management software on this cluster? I ask because if there is PBS, Gridengine, LSF etc. installed there will be an 'integration; with OpenMPI

I don't know how to run it on other nodes as well. Help needed. Ahsan, you have a Dell cluster. Can we ask which company installed the cluster, and who manages the cluster?

Re: [OMPI users] WRF run on multiple Nodes
Dear David, I don't know where the machinefile is ?. I found a command *Running with Open MPI mpirun -np 168 -mca btl self,sm,openib –hostfile /home/demo/hostfile-ompi.14 -mca mpi_paffinity_alone 1 ~/WRFV3.2.1/run/wrf.exe.* for* *Dell PowerEdge M610 14-node cluster with Mellanox QDR InfiniBand Switch , but I am still not able to make it run with my system. i have Dell PowerEdge M600 cluster with Infiniband. > Message: 3 > Date: Fri, 1 Apr 2011 22:02:59 -0700 > From: David Zhang <solarbik...@gmail.com> > Subject: Re: [OMPI users] WRF run on multiple Nodes > To: Open MPI Users <us...@open-mpi.org> > Message-ID:

[OMPI users] WRF run on multiple Nodes
Hello, I want to run WRF on multiple nodes in a linux cluster using openmpi, giving the command *mpirun -np 4 ./wrf.exe* just submit it to the single node . I don't know how to run it on other nodes as well. Help needed.
