[Halld] Monitoring launch ver 18 @ NERSC

[David Lawrence]

Hi All,

  Here is an update on monitoring launch ver18 of the RunPeriod-2018-01 data @ NERSC:

Most of the jobs have finished (>98%). The remaining issues have caused us
to asymptotically approach 100% completion. One issue in particular has to do with the job
ending improperly. Because we ran on KNL (much better availability) the jobs took
9 or 10 hours to complete, thus causing a 1 day debug cycle.

At this point, I think interested people should not wait to start looking at the outputs (if
you haven’t already started). As a reminder, the files can be found in:

/mss/halld/offline_monitoring/RunPeriod-2018-01/ver18

I will continue to work on finishing off these last lingering jobs. I have also been working 
with SciComp to resolve the transport issues. I hope to start another similar sized 
campaign next week so we can get to the point where we are confident enough to
start a recon launch at NERSC by the end of the year.


Regards,
-David

P.S. For those really interested I’ve started documenting some of the details about NERSC
running here:
