~/Src/petsc/src/snes/examples/tutorials barry/fix-petsc $ grep joe ex1.c ~/Src/petsc/src/snes/examples/tutorials barry/fix-petsc $ echo $? 1 Well jeepers I just make grep “CRASH”. A nonzero return code denotes some condition, it doesn’t denote a crash. Barry On Feb 21, 2014, at 12:19 PM, Jeff Hammond <[email protected]> wrote:

Just configure MPICH such that snprintf isn't discovered by configure and you won't see these messages.

The other solution is to fix PETSc so that people can't crash it so easily ;-)

Here we go again. It is not CRASHING; it has detected an error conditioning and trying to appropriately and cleanly terminate. The reason it needs to use MPI_Abort() is that often detecting error conditions is not a uniformly collective thing.

Printing a suitable error message and ending is not crashing. But with all the badly formatted “error messages” printed by MPICH I can not control at the end it looks like it is crashing.

You're returning a non-zero exit code, which I consider crashing. I apologize if this definition disagrees with yours. If this is just gentle cleanup, why not exit with code=0 as Jim suggested already?

If you can find a way to call MPI_Finalize instead, you will portably eliminate these messages.

A lesser solution would be to provide an error code of 0 (or MPI_SUCCESS) to MPI_Abort, e.g. MPI_Comm_abort(MPI_COMM_WORLD, MPI_SUCCESS). This would eliminate the error message that you are getting from the job launcher. MPICH could be modified to be quiet about the abort when the application aborts with an error code of MPI_SUCCESS.

Is there any way to turn off MPICH (and others) printing messages about MPI_Abort? We have already prepared and presented useful error messages to the user about the situation and would like to avoid having these additional messages printed (that often make the situation look worse than it is)

Thanks

Barry
