[mpich-discuss] Problems running mpi

[Dave Goodell]

Also, re-reading your error message you are getting a signal 11  
(SIGSEGV) on one of your processes, which means that you have a  
segfault somewhere.  It might be in MPICH2 somewhere (1.0.6 is very  
old) but there's a good chance it's in your user code somewhere.   
Upgrade your MPICH2 version and if you are still having trouble turn  
on core files and see where the code is segfaulting.
