    • Serial and HPC have same speed in Garching

Validation Testing


  • Technical Forums:
  • Warnings: Getting there
  • Testing


  • Sent an email to all interested people to have an HPC telecon this Thursday at 16:00 UTC. This is to go through the list of development items for 2016. The agenda is available in

Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
  • Sandra Castro
    • Had a team meeting with Justo and Julian to consolidate the list of development items for the HPC project.

    • Investigated test_plotms failure
      • change in VIVB2 caused exception in plotms; Jim fixed TransformingVi2 for this use case

      • RTT - tested successfully by B&T group
      • Updated documentation XML files for CAS-2502 (remove highres "Always true for jpg and png") and CAS-7733 (add "must set selfscale=True" when using sharedaxis)
      • Lindsey reported iteration plots are blank except first one - rescheduled ticket
      • Fixed exporting iteration plots at screen resolution - BUT didn't work for grid - reverted code to do high-res exports only for now
    • CAS-1977 RTT (Set dpi, width x height for plotms exports)
  • Kumar Golap
