Subject: Re: [OMPI users] Hide Abort output

Indeed, the small paragraph can be misunderstood, but that wasn't the goal of
my question.

The fact is that the message can appear in the middle of logs, which means
post-treatments of outputs even if the end of the program is normal (the
worflow does not end by a join node). I just want to be able to get rid of
the message, maybe with a special option -- or no message by default, and the
message appears when mpirun is invocated with a special debug option?

.Yves.
