VEGAS Team Meeting

Agenda:

1. Status of DIBAS software
2. review of schedule
3. plans for testing for this week

Meeting notes:

1. Status of DIBAS software
   • Ray is setting up China-style environment and adding back-ends.
   • want to test existing s/w before adding new back-ends
   • would like to reserve DIBAS v. VEGAS test time - need to coordinate with Jason
   • Next shipment to SHAO scheduled for 17-Jan
2. review of schedule
   • RFI testing complete
   • Richard to update schedule
3. plans for testing for this week
   • Amanda to test modes 20-29 with eight banks this week.
   • Has anyone done a long integration test to see if noise is integrating away? (Amanda to test after all eight banks are working)
     • Some ringing and combing has been seen; Amanda will circulate spectrum identifying the features that seem an anomaly.
4. Other
   • HPC problem continues to vex and is seen on multiple machines. A test program has been created to try and stress the problem. Vendor should be able to assist in troubleshooting
     • May be ale to add a new nVidia driver on one of the HPCs and see if problem occurs.
     • Establish a periodic re-boot regimen while development and troubleshooting continues
     • New HPC 10 & 11 are from a different manufacturing batch and we cab install in HPC8 to see if problem occurs
   • Glenn would like to see certain ADC level values stored for observations for review and debugging
     • record final ADC 'snapshot' from leveling activity - Ray to investigate and implement after DIBAS modes are complete
     • IF levels would be useful as well
