[ODE] low CPU utilization ...

If you're on a HyperThreaded P4 and are actively using only one
thread; then if that thread runs at "full utilization", the OS will
still report 50% CPU activity (because it treats it like 2 processors,
and one of them seems idle).

Then, if you by chance have some dual-whatever CPU with HT, the OS
will see it as 4 CPUs. One thread can't take more than 25% of that.

Does your simulation run slow? Or are you just worried about OS not
reporting "full utilization"?
