Re: [OMPI users] WRF run on multiple Nodes

2011-04-05 Thread Ralph Castain
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.

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

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.

I ask because if there is PBS, Gridengine, LSF etc. installed there

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.

[OMPI users] WRF run on multiple Nodes

2011-04-02 Thread Ahsan Ali
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.
