Page for tracking an apparently slow down w.r.t CASA-5 and CASA-6 for VLASS calibration: https://open-jira.nrao.edu/browse/PIPE-568
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.
Full, serial pipeline with small dataset
RHEL7 - 6.7GB dataset with NM Lustre-2.5.5 (results are in minutes)

RHEL7 - 6.7GB dataset after NM upgrade Lustre-2.10.8 and CV results copied from last test (results are in minutes)

Mar. 3, 2020 krowe: I tried the nmpost051-casa6-rhel7 with the latest casa-pipeline-validation-17. The run-time was the same as were the tclean() errors.
"*" Means it completed with tclean() errors
