Comparing CASA-5 and CASA-6 (casa-pipeline-validation-8) across the two different CPUs available for batch processing in NM and CV shows that the newer CPUs (E5-2640v3) run a small calibration job (6.7GB) about 1.25 times faster than the old CPUs (E5-2670) with CASA-6 performing slower in every case. There was no significant run-time difference between NM and CV for similar hardware and software. Results are in minutes.
Here is the full pipeline script I have used for all of these tests casa_pipescript.py For some tests, I commented out all but hifv_importdata.

You can see that running just hifv_importdata() on a larger data set (350GB) shows that nmpost nodes run about 2% to 10% faster than similar cvpost nodes with CASA-6 performing slower in every case.

Comparing two profiling jobs against one of Brian's jobs (/lustre/aoc/sciops/bkent/pipetest/llama3/workingtest60_2) on the same hardware (E5-2670) in NM. Times were calculated from the CASA logs. Times are in minutes.

K. Scott finished three runs on Apr. 8, 2020 using Brian's large dataset (350GB), CASA-6.0.0.23-pipeline-validation-17 and Pipeline master-v0.1-18-g2de4d78-dirty separated by about an hour each. Each job requested 1 node with 8 cores and 96gb; essentially a NUMA node. system.resources.memory was unset and _cf.validate_parameters = False. (Times are in minutes)
