  All Hands Meeting:
  
  We expect the meeting to last 2.5 days, during which we will (among other things):
  1) Review the impact of our Phase I and Phase II activities on our stakeholders (experiments and HPC centers)
  2) Highlight early results and open issues from each Phase II area: PAW, SOP, SIM, and SML.
  3) Discuss priorities and update milestones for Year 2 of the project, taking into account the input from our program manager and the report from the project review (which we should receive in the coming weeks).
  3a) Specifically, in Year 2, we have been encouraged to increase the scope of AI/ML activities in CCE to ~25% of the total effort
  We look forward to seeing you all in person at LBL or virtually.
