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.
