"assign" dual processors

I know most applications are not dual processor aware, and all you can really
do is let Windows manage the load, but is it possible to influence how
Windows does this? For instance, can I assign a particular processor or core
to a particular application? Ideally, when the app is running, Windows
dedicates one processor/core to that app, and everything else on the other
processor/core. When the app isn't runn ing then Windows manages the load
dynamically.
Is this possible?

Thanks,
Gordon

Yes. Open task manager, go to the processes tab, right click on the process
you want to change and select 'Set Affinity'.

Not really, not easily. You can set the affinity of the process and then set
the priority of the task to be higher than others, which should give it as
much time as possible, but it isn't dynamic.

Will that do?

Robert, it this permanant, as in the next time I boot my machine Windows
remembers that affinity setting, or do I need to do it each time I launch the
application? And if so, is the afinity setting scriptable?
