Comparing CASA-5 and CASA-6 across the two different CPUs available for batch processing in NM and CV shows that the newer CPUs (E5-2640v3) run a simple calibration job (6.7GB) about 1.25 times faster than the old CPUs (E5-2670) with CASA-6 performing slower in every case.
Running just hifv_importdata()
RHEL7 - 2.2MB dataset
| CASA | nmpost051 (E5-2640v3) | cvpost020 (E5-2640v3) | nmpost038 (E5-2670) | cvpost003 (E5-2670) |
|---|---|---|---|---|
| 5 | 114, 117 | 110, 111 | 144, 143 | 140, 141 |
| 6 | 156, 164 | 156, 158 | 200, 201 | 197, 199 |
RHEL7 - 350GB dataset
| CASA | nmpost051 (E5-2640v3) | cvpost020 (E5-2640v3) | nmpost038 (E5-2670) | cvpost003 (E5-2670) |
|---|---|---|---|---|
| 5 | 192 | 196 | 239 | 251 |
| 6 | 328 | 364, 378 | 411, 427 | 453 |
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.
Running both hifv_importdata() and hifv_hanning().
