This is an MPI question and has nothing to do with PETSc. Perhaps there are some MPI mailing lists out there for this type of question.<br>
Note: I don't think exit() is something that all MPI implementations can catch and distribute to the other MPI nodes, but this is something MPI folks would know.<br><font color="#888888">

Hi,<br>
I have setted a handler error function:<br>
ierr = MPI_Errhandler_create(errorHandler,&errhandler); CHKERRQ(ierr);<br>
ierr = MPI_Errhandler_set(PETSC_COMM_WORLD,errhandler); CHKERRQ(ierr);<br>
<br>
I have simulated a fault of processor 1:<br>
<br>
if (rank == 1)) exit(2);<br>
MPI_Barrier(PETSC_COMM_WORLD);<br>
<br>
The process remains blocked and the functions errorHandler is not called.<br>
If I use return; instead of exit(2); the process don't remains blocked, I read the error of Petsc but errorHandler is not called.<br>
<br>
Help me please.<br>
