[Pkg-openmpi-maintainers] Bug#849974: openmpi: not enough slots available

[Heinrich Schuchardt]

Package: openmpi-bin
Version: 2.0.2~git.20161225-8
Severity: normal

Dear Maintainer,

I am running on Intel Core i5-6300U CPU @ 2.40GHz.
/proc/cpuinfo reports 4 CPUs.

mpirun -np 2 --hostfile hostfile python -c "print 'hello'"
works fine.

mpirun -np 4 --hostfile hostfile python -c "print 'hello'"
fails with
"There are not enough slots available in the system to satisfy the 4 slots"

https://www.open-mpi.org/faq/?category=running#slots-without-hostfiles
describes that overprovisioning should work

Best regards

Heinrich Schuchardt
