ECP updates

  • No more monthly updates (just quarterly updates)
    • Will go over more during these telecons to keep up to date
    • Need occasional highlights
      • Dave: comparison of streamlines to hard-coded algorithm
  • Prep for FY20 and beyond
    • Friday we will receive our budget for FY20
      • We were told it will be the same as FY19 and flat-lined through FY23
      • The number we will be given will be for whole project. Expect to keep same division of funding.
      • In practice this is a small year-to-year reduction
      • We should move forward in moving UO's contract to ORNL
    • We will also receive a template for a ~3 page "proposal" for what we plan to do
      • General description of what the project will do and provide
      • A very high level description of milestones
      • Due February 15, but for practical reasons we need it done next week. We will move fast. Reserve time to help respond.

ECP deliverable updates

Rountable notes

Ollie was in the hypertree hackathon last week. Learned a lot about hypertree grid in VTK-m. Helped fixed a few bugs.

Matt spent the week complaining about install not working. There should now be tests for that.

Rob has spent some time making sure all headers get installed.

Haochang finished asynchronous timer code. MR is there. Working on some test failures.
