Of course, I need to test the trigger DST on sgi2 also, to make sure I'm not looking at architecture issues. My algorithm uses angles, hence trig functions, hence more floating point; and it wouldn't surprise me if SGI were relatively better at floating point than Intel.
Running on an IMU trigger DST, first file, gives: My Algorithm 18.85 seconds and 2909 raw CdfMuons; Bob's 24.21 seconds and 2564 raw CdfMuons.
| Algo | Where | Fileset | Full time | module's time | Memory | Raw CdfMuons |
| Original | sgi2 | 22 Bottom files | 15193 | 514 | 85 | 990 |
| Handler | sgi2 | 22 Bottom files | 15497 | 711 | 89 | 760 |
| Original | sgi2 | 1 IMU trigger DST | - | 18.5 | - | 2909 |
| Handler | sgi2 | 1 IMU trigger DST | - | 24.2 | - | 2564 |
| Original | Linux P4 | 7 IMU trigger DST | - | 40.13 | - | 20236 |
| Handler | Linux P4 | 7 IMU trigger DST | - | 26.21 | - | 17612 |
