[mpich-discuss] exit without calling finalize（windows xp pro 64bit）

[Jayesh Krishna]

Hi,
 The error message says that one of the MPI processes exited before calling MPI_Finalize. This usually occurs when one of the MPI processes exits prematurely (segfault etc). I would recommend debugging your code further to find the source of the problem.

(PS: The error message can also occur if there is a bug in MPICH that causes the application to abort - however I would recommend debugging the application first to find the exact source of the problem.)

Regards,
Jayesh

Dear all ， 



I recently have written a program which calls MSC.Patran and MSC.Nastran over and over again until find an optimal solution, in the visual studio 2010 C++ environment on Windows XP professional 64bit. And the version of mpich2 is 1.4.1p1( 32bit). 

Build, run the program and then wait. Sometimes, I can get an optimum solution when the parallel is done. But mostly, the optimization terminates unexpectedly, and error message follows: 



job aborted: 

rank: node: exit code[: error message] 

0: yang: 123 

1: yang: -1073741819: process 1 exited without calling finalize 

2: yang: 123 



Any advice? 

Thanks for your help! 



Yang Junbo
