--- Comment #8 from Laurent Chardon <laurent.chardon@gmail.com> ---
I also think that the default option should not depend on Slurm, as I see no
reason for it. MPI and batch scheduling are complementary but distinct from
each other. In fact, it appears from the above comments that Slurm and MPI are
not currently used together on FreeBSD.

I'll make flavors of openmpi and mpich with Slurm, with the base being
independent of any scheduler. I won't make a TORQUE flavor, as it seems to no
longer receive updates. The last TORQUE release dates back from 8 years ago and
sysutils/torque is flagged as deprecated with expiry set to the end of this
month. 

I would have liked to make these changes at the next version upgrade, as there
is a chance, even if minor, that it will create a disruption to some users. I'd
rather not do that in a port revision if it can be avoided, but the TORQUE
removal is somewhat forcing my hand.

Thoughts?
