[mpich-discuss] MPI error, error stack

[wzlu]

Hi,

Thanks for your responds.

I will ask the program owner first, if he agree I will send the program 
to you.

I also have read the man page in my system(RHEL 5). The signal 8 is 
"Floating point exception".
Does it mean some code in the program cause this error? And I have to 
trace the code to solve the program?

I know the program runs well in AIX 5.3, maybe run well in linux too.

Best Regards.
Lu
