A similar test on psanaq:
| Nodes | Cores/Node | Import Time (s) | Detector Creation Time (s) | Analysis Time (HH:MM:SS) |
|---|---|---|---|---|
| 2 | 12 | 16 | 9 | 2:05:53 |
Conclusions
- Unlike Jan. 27 measurements below the hyper threading cores didn't seem to help. Feels like "operator error" on my part?
- Nodes with 10Gb NICs vs. 1Gb NICs didn't make a significant difference
- Best configuration seems to be 2 nodes with 64 cores/node.
- "import psana" times fairly small. Detector creation times (fetching calibration constants?) larger.

| Nodes | Cores/Node | Time (HH:MM:SS) |
|---|---|---|
| 2 | 64 | 16:06 |
| 1 | 64 | 27:31 |
| 1 | 32 | 1:43:29 |
| 2 | 128 | 16:11 |
| 1 | 120 | 16:45 |
| 2 | 240 | 19:17 |
Redo these tests on March 6, 2021. Can't reproduce the benefit of the hyper threading cores:
