Subject: Re: [OMPI users] MPi Abort verbosity
From: Gabriele Fatigati (g.fatigati_at_[hidden])

Hi Nadia,

thanks for quick reply.

But i suppose that parameter is 0 by default. Suppose i have the follw
output:

- ------------------------------
--------------------------------------------
- --> MPI_ABORT was invoked on rank 1 in communicator MPI_COMM_WORLD
with errorcode 4. <--

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
- --------------------------------------------------------------------------
Inside my_mpi_err_handler
Inside my_mpi_err_handler
I am 0 and we are in 2
I am 1 and we are in 2
- --------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 3773 on
node nb-user exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
- --------------------------------------------------------------------------
- --

I would like to see only this:

- --> MPI_ABORT was invoked on rank 1 in communicator MPI_COMM_WORLD
with errorcode 4. <--

And nothing else. Is it possible?

I can upgrade my OpenMPI if necessary.

Thanks.
