[mpich-discuss] There is any change between mpich1 and mpich2 which make this error?

[Jim Dinan]

Hi,

It looks like one of your processes seg. faulted and exited with SIGSEGV 
(signal 11).  You should be able to look at the core file or attach a 
debugger to get a backtrace and locate the origin of  the error. 
Without more information, it's hard to give much help.

MPICH2 1.4.1 is also a slightly older version, you could try upgrading 
to the latest version of MPICH and see if the seg fault goes away.

I don't know of any change from MPICH1 to MPICH2 that would have 
resulted in a correct MPI-1 program seg faulting.

  ~Jim.
