Apologies if this has been covered in a previous thread - I went back through a lot of posts without seeing anything similar.
In an attempt to protect some users from themselves, I was hoping that OpenMPI could be configured so that an MPI task calling exit before calling MPI_Finalize() would cause job cleanup, i.e. behave effectively as if MPI_Abort() was called. The reason is that many users dont realise they need to use MPI_Abort() instead of Fortran stop or C exit. If exit is called, all other processes get stuck in the next blocking call and, for a large walltime limit batch job, that can be a real waste of resources. I think LAM terminated the job if a task exited with non-zero exit status or due to a signal. OpenMPI appears to cleanup only in the case a signalled task. Ideally, any exit before MPI_Finalize() should be terminal. Why is this not the case? Thanks, David
