Hi, 

When I run a parallel program, I got an error : 
------------------------------------------------------------------

--------------------------------------------------------------------------
mpirun has exited due to process rank 24 with PID 129522 on
node n333 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
--------------------------------------------------------------------------
---------------------------------------------------------------------------------------
But, the program only run for not more than a few of minutes. It should take hours to finish. 

How can it reach "finalize" so fast ? 

Any help is appreciated.
