I guess Control-C will kill only the mpirun process.
You may need to kill the (two) jules.exe processes separately,
say, with kill -9.
ps -u "yourname"
will show what you have running.
Something may have been left behind by Control-C,
although as Reuti and Ralph said that is unusual.
Besides the jules.exe and mpiexec,
check for the orted process also,
which may need to be killed manually.
Just in case: Better not run MPI programs as root,
but as a regular user.

Hi all,
This is a really simple problem (I hope) where I’ve introduced MPI to a
complex numerical model which I have to kill occasionally with Control-C
as I don’t want it running forever.
I have only used mpi_init(), mpi_comm_size(), mpi_comm_rank() and
mpi_finalize()– there are no send/receive calls going on at the moment –
and I only have two instances. My startup command is:
#/bin/bash
/opt/openmpi/bin/mpirun -np 2 -hostfile hostfile jules.exe
where hostfile has one entry : localhost
The result of terminating the process with Control-C at the command
prompt from where I launched it, is that I am then unable to run it
again. I get the
“mpirun has exited due to process rank 0 with PID 10094 on node
metclcv10.local exiting improperly. There are two reasons this could
occur:…” error each time despite checking running processes for
stragglers, closing my terminal, or changing node.
I have spent several hours searching for an answer to this, if it’s
already somewhere then please point me in the right direction.
many thanks in advance
Jane
