[mpich-discuss] failed processes

[Darius Buntinas]

Hi Harun,

If you use MPICH2 1.3, and pass the -disable-auto-cleanup parameter to mpiexec, then your app will not automatically be killed when a process dies before calling MPI_Finalize.  You'll then need to set the default error handler in MPI to MPI_ERRORS_RETURN, so that the application won't abort when an error is detected.  

The MPICH2 library should allow you to continue communicating with other processes if a process dies.  However, collective operations on a communicator that includes a dead process will most likely hang some processes.

I hope this helps.
