Re: [OMPI users] Fwd: Fwd: problem in cluster
That fine. But in your job script ppn=2 Also check ldd cgles on the compute servers themselves. Are all the libraries available in your path?

Can you please tell me whether to use mpicc compiler ar any other compiler for openmpi programs On Wed, Apr 25, 2018 at 3:13 PM, Ankita m wrote: > i have 16 cores per one node.

Re: [OMPI users] Fwd: Fwd: problem in cluster
i have 16 cores per one node. I usually use 4 node each node has 16 cores so total 64 processes.

Re: [OMPI users] Fwd: Fwd: problem in cluster
I do not see much wrong with that. However nodes=4 ppn=2 makes 8 processes in all. You are using mpirun -np 64 Actually it is better practice to use the PBS supplied environment variables during the job, rather than hard-wiring 64 I dont have access to a PBS cluster from my desk at the moment. You could also investigate using mpiprocs=2 Then I think with openmpi if it has compiled in PBS support all you would have to do is mpirun Are you sure your compute servers only have two cores ?? I also see that you are commenting out the module load openmpi-3.0.1 I would guess you want the default Opnempi, which is OK First thing I would do, before the mpirun line in that job script: which mpirun(check that you are picking up an Openmpi version) ldd ./cgles (check you are bringing in the libraries that you should) Also run mpirun with the verbose flag -v On 25 April 2018 at 11:10, Ankita m wrote: > >> while using openmpi- 1.4.5 the program ended by showing this error file >> (in the attachment) >> > > I am Using PBS file .
