NUG Meeting Jan 20, 2022 - Running climate models on Cori

January 20, 2022
Date: Thursday, January 20, 2022
Time: 11:00 PST


The Monthly NUG Meeting is a regular opportunity for our users to show off what they've done, for NERSC to get feedback from users, and for users to exchange ideas.

  • Win-of-the-month: open discussion for attendees to tell of some success you've had - eg getting a paper accepted, solving a problem, or achieving something innovative or high impact using NERSC
  • Today-I-learned: open discussion for attendees to point out something that surprised them, or that might be valuable to other users to know
  • Announcements and CFPs:  upcoming conferences, workshops, or other events, that you think might interest or benefit the NERSC user community
  • Topic-of-the-day: Run-time configuration for climate models on Cori —throughput per job or throughput per year? Koichi Sakaguchi from PNNL will talk about experiences running climate models on Cori, including some observations about the impact adjusting sbatch parameters has on workload throughput.
  • Coming up: Nominations and requests for future topics. We're especially interested to hear from our users - what are you using NERSC for, and what are you learning that might be helpful for other NERSC users, and for NERSC?
  • Last month's numbers: NERSC center metrics and info for the most recent month
