  • https://safe.nrao.edu/wiki/bin/view/HPC/CasaParallelTaskList
  • Revision in progress this week.
• User to task interface translation discussion
  • Enumerate parameters that can or should be specified (time, frequency) discussion of channel vs frequency
• Status of End to end testing
  • Lindsey creating benchmarking pipeline ?
  • Greg using Steve's script to generate baseline timing, script to then be parallelized
