Hi Brock, Angel, Reuti,
You might want to look at a tool we developed:

This was actually one of the drivers for isolating the persistent ORTE DVM
thats being discussed in this thread.

And does it also work as expected after you have build it? :-)

Hi Erik,
Do you really want 1.8.7, otherwise you might want to give latest master a try.
Other including myself had more luck with that on Cray's, including Edison.

Can confirm the fallback works now without setting explicitly to basic (with
the merged changes).
Thanks!

Hi guys,
Thanks for the follow-up.
It appears that you are ruling out that Munge is required because the system
runs TORQUE, but as far as I can see Munge is/can be used by both SLURM and
TORQUE.

Ok, so I now know that munge is ... :)

Is that something actively running or do you mean library available or such?

That doesn't seem to make a difference.
Have their been changes in this area? Last time I checked this a couple of
months ago on Edison I needed this flag not to get spammed.
e-submit and friends, so I "explicitly" don't want to use
aprun.

Depends on the use-case, but happy to leave that out of scope for now :-)

Hi,
Any users of Open MPI on Blue Waters here?
And then I specifically mean in "native" mode, not inside CCM.
After configuring and building as I do on other Cray's, mpirun gives me the

Hi Ralph, all,
To give some background, I'm part of the RADICAL-Pilot [1] development team.
RADICAL-Pilot is a Pilot System, an implementation of the Pilot (job) concept,
which is in its most minimal form takes care of the decoupling of resource
acquisition and workload management.
So instead of

Hi,
Would it be possible to initially run "idle" orted's on my resources and then
use orterun to launch my applications to these already running orted's.
Thanks!
