Targets/tasks for May 11th - 18th
For next monday some description of memory consumption
Discussion/Agenda
Memory requirements in imaging
Total memory scaling is generally understood
Need to compare expected memory use with actual use (Jim has some instrumentation in place) (target)
Need to understand better how temp image selection works, whether it's correct and how to modify it for parallel cases (target)
Describe and implement engine vs threaded gridder determination as a function of memory
Update on Partitioning status (null selections, non-conforming tasks)
Jeff
First tasks being implemented (flagger, calibration), some read in parallel, all can read serially, writers are still problematic
Re-examination of Parallel-go for cluster specification (cores vs engines, memory)
Model data tests
James to get with Kumar
Memory resident subtable tests
James
Check that it affects number of FDs as well
Spectral imaging tests
James
Understand channel chunk choice effect on performance
James
CASA HPC Initiatives for the 3.5 Cycle
Tentative list from last meeting
Reduce in memory requirements during imaging
Parallelize multi-field imaging
Parallelize MFS terms > 1 in the gridding step
Parallelize Cube imaging scatter gather
Expand threaded gridder case to >4 threads
Implement core affinity for threaded gridder case (first out)
Parallel framework (partitioning, parallel go) work in ESO
Filler to write a MMS in parallel
