Monday, April 6, 2020

Attendees - Rusty Davis (rstyd), Pat Grubel (pagrubel), Qiang Guan (guanxyz), Tim Randles (trandles-lanl), Jake Tronge (jtronge)

PR Review

  1. #138 APPROVED (trandles-lanl) - Use bee.conf to configure listen ports for BEEWorkflowManager and BEETaskManager
    • Pat approves of merging this PR, but into master instead of develop. The rationale is the functionality is simple and enables everyone to do development work at the same time on the same system.

    • initial problems with PySlurm due to having a too-new Slurm installed

    • not a lot of time for BEE this week (very understandable, everyone prioritized BEE the past 2 week (trandles-lanl))
  • Pat
    • unittest for TaskManager
    • issue #137 above
    • not much time for BEE this week
  • Tim
