Project Updates
  • NSF visit good
  • office space La Serena - not enough  and not efficiently used
  • FY23 starts - amendments not yet approved but could be done this week
  • Ops contracts language for software not same as construction. Double check the IP language in your contracts and make sure it matches construction phasing, WOM/FE chasing up Contracts
  • Flights still expensive - overestimate TRs (its better than under estimate)

Commissioning the Commissioning Cluster on Cerro Pachón 

  • Cristián Silva at the f2f we agreed to expand Yagan, we need to know by how much
  • Robert Lupton we never set up antu as the commissioning cluster - antu now gone
  • Gregory Dubois-Felsmann to clarify yagan is where rapid processing will run
  • Currently Parsl over SLURM at USDF .. may be more flexible for Yagan than PanDA
  • Colin Slater this will create a difference between summit and USDF
  • Rapid processing is same system as prompt processing which is what is running at the IDF which is neither PanDA nor Parsl/SLURM
    • Question to Paul Price and James Chiang as to whether Parsl has the same capabilities as HTCondor in BPS (at present and in the future) — need to enumerate missing capabilities.
  • Current USDF HTCondor is "personal" only — Expertise at NCSA available to help stand up HTCondor as a service at USDF
    • Likely can run batch system on Kubernetes-managed nodes, not necessarily bare metal, need to confirm; Robert Lupton and Gregory Dubois-Felsmann do not need to verify performance on Kubernetes at this point, only functionality; Steve Pietrowicz will confirm that HTCondor can run on Kubernetes; Richard Dubois will determine if Parsl/SLURM can run on Kubernetes
  • Current number of cores in yagan (now that antu has been moved) should be quite sufficient for near-term Rapid Processing

ADASS registration (Tim will experiment on how to pay)
TCAM Stamdupas needed

DMLT Action Items (Confluence quick tasks)

Confluence action items on DMLT meeting minutes pages are meant to be mainly low-level actions that can be completed quickly.  More substantial tasks should appear in JIRA.  The label "DMLT" can be used (with any component) to mark a task as resulting from a DMLT action item.

  1. For ctrl_bps_parsl:

    • bps cancel  is not really applicable: to cancel a run, you Ctrl-C  out of the bps submit  process that you're running.
    • bps report  is not yet implemented.
    • I have recently answered questions about whether it respects memory requests. The answer is that it depends on how you have it configured. A Slurm  site does not respect the memory requests because all the resources are identical. A TripleSlurm  site does respect the memory requests, and sends the job to the appropriate slurm block. I believe the WorkQueueExecutor is capable of respecting memory requests, but I don't think the WorkQueue site we have configured passes along the information.
    • What other capabilities are you interested in that I've omitted?
