1. I am running the with the default LAM-MPI that comes with fedora core-2.
2. I give the following command for running mpi jobs
$ mpirun -np 4 ./mpi-x-povray +h400 +w400 +D
3. I run top command on both head/master and slave node. I find that all the four jobs run only in the master node and not in the slave node.
Regards,
Rajiv

Subject: Re: [Oscar-users] problems running mpi applications in OSCAR-4 in Fedora-2
Can you be a bit more descriptive?
- Which MPI implementation are you using?
- What are the exact commands that you are using to run MPI applications?
- How are you verifying that all the processes are starting on your head node?
Thanks.

Dear All,
I have sucessfully completed OSCAR-4 installation in Fedora Core-2. I am facing facing problems running mpi jobs. All MPI jobs are running only in master node no matter how many processor job I give. I have tried several options but still the same thing happens. However the PVM version of one application-POVRAY is working fine. The MPI version POVRAY is giving the above problem. How to solve this problem. Pls help me to break this problem.
Regards, Rajiv
