Hi guys,
I updated my ubuntu version to ubuntu 16.10 and cannot execute programs
with mpirun anymore :(.
I did not encounter this problem with ubuntu 16.04 and would really
appreciate some help.
I am running ubuntu 16.10 with the kernel version 4.8.0-46-generic on a
Lenovo y50-70 laptop with the current version of openmpi available via
apt-get libopenmpi1.10 openmpi-dev openmpi-bin
my code compiles and links perfectly, I only get trouble when trying to
launch with mpirun. I can even run a simple hello world mpi code.
_running: mpirun -np 2 ./helloWord:_
When I run mpirun -np 2 ./progname my program does not even launch. The
terminal remains blank and I cannot even kill the processes in htop with
kill PID or kill -9 PID. Rebooting or shutting down ubuntu via the
shutdown button on the ubuntu desktop has no effect and I have to
manually shutdown by holing down the power button.
_running mpirun -np 1 hostname:_
It works on the first run but subsequent runs are killed immediately.
The output looks something like this
$ mpirun -np 1 hostname
Killed
Has anyone experienced something like this before?
Thanks in advance
John.
