  • ATNF site report (Cormac Reynolds)

Things to do Wed-Fri

  • Why is interlaced VDIF showing low weights for GMVA?
  • Why is complex interlaced VDIF data not fringing in DiFX-2.6.1?
  • Why do DiFX logs cut out mid-correlation on OzStar?
  • Why does DiFX not work under slurm when inside a screen session?
  • Test outputbands on ASKAP oversampled/overlapping data after changing autobands logic to select channels closest to the centre of recorded band in the case that multiple options are available.
  • Datstream filelists (Cormac + Walter)
  • PolConvert single dish mode and document
  • DiFX segfaulting on OSX
  • difx2mark4 pcal support for multiple streams
  • One baseline missing from R4s - try reducing number of stations?
  • Tbd Shanghai correlation issue
  • Adding cpumon to report current cpu speed and current power dissipation
  • Get more info on the USNO benchmark lack of repeatability
  • Mark6 playback speed (locally high, but via network speeds are slower)
  • Python3: audit of current changes, what is the strategy going forward.
  • Libraries not appearing when running DiFX on ozstar under slurm
  • MPI parallel tracing of DiFX to look for bottlenecks
  • Generate some one page EOIs for the next call for SSEs on ADACS
  • See whether ADACS would co-supervise DiFX student
  • Antenna in v2d file that is not used crashes vex2difx??
  • Geoff to figure out how to not correlate a recorded band(RTFM more carefully):-)
  • How to allocate nodes in a specific order under slurm
  • Start an overleaf project for DiFX3 paper * Mine the ChangeLogs to get this process started
  • Absolute paths in difx input files - is there a way to deal with them better?

* Can vex2difx parse only the antenna blocks that are in the antenna list?

  • Virtual trunk missing components
