  • 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
  • Topic-of-the-day: Today's topic is "Parallelware tools for detecting code optimization opportunities". Manuel Arenaz and Javier Novo Rodríguez from Appentra will demonstrate using Parallelware Trainer and Analyzer tools to parallelize the Canny edge detector image processing algorithm, using multithreading, SIMD and offloading. These tools are available on Cori via "module load pwtrainer" and "module load pwanalyzer", and release notes for the latest versions are at and
  • 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
