Discussion/Agenda

• Casa Async I/O discussion
  • Recap of Ger's visit and Jim's presentation
    • Will fix MS iterator
  • Where to from here
  • Will follow Jim's recommendation, if Ger implements something at the table level we'll consider adopting.

  • Need 100GB continuum Sanjay
• Generate baseline timings for test data sets Greg
  • Should also save manually generated mask
• Specify benchmark/timing test procedures James/Greg
  • Specify results
• Time domain partitioning with multiple MSes per imaging process Kumar
  • File locking issue if master node is doing gather and scatter
  • Progress this week
• Cluster scheduler scripting with CV James
  • Discuss with Jim semantics for cluster/CASA interaction
• Cluster resource definitions Jim
• Discussion on pclean functionality
  • Can be used now by normal users if they're told how
