Problems on running cfx in parallel

March 28, 2006, 21:58

I try to run cfx5.7 in a supercomputing center. The hardware is IBM Power 4, the system is aix 5.2. They don't support pvm. So I use loadleveler to submit my command:

cfx5solve -def xxxx.def -s 1.2 -start-method "MPICH Local Parallel" -part 10

After the cfx finished the partitioning, it stopped.

An error has occurred in cfx5solve: | | | | The CFX-5 solver exited with return code 1. No results file has | | been created.

Can anyone tell me what is wrong here?

Thanks in advance.

The command should be okay if your machine support MPICH...

1. check if you have 10 unused par_proc license. 2. check if you have other MPI driver that work for your IBM machine. Maybe talk to your system adminstrator first. I remember that I have some problem using PVM in my SGI machine and admin has installed a SGI MPI driver to solve this problem. 3. try a serial run with the same def file and see if that solve okay.

Good luck
