| Tuning |
Chip 1's virtual CPUs (0-63) were left in the default processor set, and group 1 was run there. An explicit processor set was created with all of chip 2's virtual CPUs (64-127) assigned to it, and group 2 and the Controller were run in that processor set. All software power management was disabled.
