[CIG-SHORT] Fault Output

[Brad Aagaard]

Bobby,

It wasn't clear from your description if you are comparing serial and 
parallel runs on the cluster or a serial run on a laptop with a parallel 
run on the cluster. I think the first step is to verify that a serial 
run on the cluster matches a serial run on your laptop. The next thing I 
would do is to test serial and parallel runs for simple examples like 
those in examples/3d/hex8 (or some of the other provided examples). You 
want to isolate the specific conditions/parameters when things may be 
going wrong.

Regards,
Brad
