ongoing/upcoming activities

Second hackathon

github.com/OFDataCommittee/OFMLHackathon

In a nutshell:

  • Jan 23-25, ~15 participants
  • three projects: DRL for flow control,
    Coupling OF and SmartSim/SmartRedis,
    comparing OF to Nvidia Modulus
  • platforms: gather.town and Slack

Three very productive days!

Our observations:

  • enormous engagement/motivation
  • relatively high dropout rate (~50%)
  • good progress in DRL and SmartSim coupling
  • Modulus challenging to run on our AWS resources
  • active support by HPE (Allesandro Rigazzi, Andrew Shao) and Nvidia (Niki) - thanks!

Thanks to Neil for sponsoring the resources!

Next hackathon

  • probably July/August
  • projects: DRL+SmartSim continuation, ParaView+DL?
  • beginner projects?

Suggestions? Volunteers (projects, mentoring)?
