Parallel startup trouble!

John

Hello all!

I have a definition file made using CFX-5.6 that has run successfully on a Sun SMP machine using the 5.6 solver. Now I am trying to run it on a Linux cluster with the 5.7.1 solver, default PVM executable. The solver seems to have trouble starting. I notice by top-ing compute nodes that the CPUs are surging up and down. This all occurs after the mesh is partitioned with no problems whatsoever.

The compute processes (pvmsolve) die off one by one, and the output file ends before reporting the first iteration results.

I thought that this might be due to a poorly defined mesh or partition, but I can't understand why it would run on one machine and not another. Any clues as to the nature of this problem would be greatly appreciated!!

Thanks,

John
