• VE-228: 32-channel BOF files (IN PROGRESS)
• VE-229: Update existing BOFs with delay register and wrap behavior improvements (IN PROGRESS)
• VE-222: Upgrade post-processing scripts to handle multi-bank data with overlapping frequency coverage (IN PROGRESS)
• VE-230: High time resolution modes

Story Details

VE-226: Continue work on spectral line modes in VPM branch

• Ray not present but Joe reports that he has a manager version with the mode parameter as an enum.

VE-216: Continue work on Matrix book keeping

• Testing switching book keeping.

VE-227: Continue Manager/Matrix interface work

• Defined all interactions between manager and matrix.
• Will allow one to run "classic" HPC or Matrix HPC, which will be helpful for regression testing.

VE-231: Shared memory bug on dev-test

• Two issues
  • Could not compile due to cfitsio version conflict.
  • Configures for GUPPI shared memory parameters but needs VEGAS version.
  • Both of these should be fairly easy to fix.

VE-228: 32-channel BOF files

• Randy and Jason a i0800x0032 BOF and emailed Natalia for testing. Randy not present; Jason not sure of status of other modes.

VE-229: Update existing BOFs with delay register and wrap behavior improvements

• Luke building a c0800x4096 BOF with fixes and a 24-tap PFB.

VE-230: High time resolution modes

• No updates.

VE-222: Upgrade post-processing scripts to handle multi-bank data with overlapping frequency coverage

• On hold while Ryan was on vacation. Ryan needs to make sure data from different files are being collected properly using MPI.

VE-215: Spectral line regression testing

• Waiting on release candidate. Target date for testing is May 4th.

Additional Work

• Identified hardware for second bank of development environment. Has necessary memory, GPU, and 10-gig card. Not sure where it came from but Dave Woody scrounged it up. Dave and Wolfgang are working on set up and software team can then configure as necessary.
• Jason also located the additional 10-gig switch, which is curently in the beamformer rack. Beamformer team will be shipping their own within a week or two, at which point this switch will become available.

VEGAS Pulsar Project Meeting - Sprint Planning: 2017 April 3rd 2:00 - 3:00pm ET

Note: The team's "velocity" has been consistent at 11--13 points per sprint. We should aim for 12 points per sprint for planning purposes.

Backlog

• Prepare a release candidate for the re-based VPM branch that can run spectral line modes as expected
• Spectral line regression tests of release candidate
• Various Matrix work
• Continue work on high time resolution modes
• 32-channel BOF files
• BOF file cleanup and improvements
• Post processing scripts for multi-bank data
• Fix shared memory bugs in dev-test (related to cfitsio and software versions)

Critical Issues

• M&C system and regression tests
• Manager parameters and interface with CLEO
  • This may be close to done on the manager side. Will need to coordinate with Ron to make sure that CLEO has everything it needs to build GUI.

New Stories

• Joe will continue Matrix work for bookkeeping and FITS writer, as well as LBW spectral line mode work.
  • Will need to pull Ray's changes for mode enums in manager.
  • May be able to start on pulsar modes.
