This is pretty cool!

Over the weekend I had time to play with a sweet little utilty for WinNT/2000. If you've ever gone in to the task manager and tried to set processor affinities, you need this utility! 16 year-old Mike Lin has done us all a service by writing an app called "SMP Seesaw". Here's the scoop:
SMP Seesaw is a small utility for dual-CPU workstations that allows the user to finely tune how Windows balances the processing load between the two CPUs.

By default, Windows tries to balance the processing load as evenly as possible: when one process is running on CPU 0 and another process needs to execute, Windows runs it on CPU 1. This greatly improves multitasking performance under Windows NT and even moreso under Windows 2000. However, it is sometimes useful to dedicate an entire CPU to only one or two processes to get maximum performance from them - single-threaded games, software-based DVD playback and VMware ( are good examples.

The Windows 2000 task manager allows the user to set "process affinities" that force a process to execute on one processor only. However, there is no practical means to isolate one or two processes to a CPU and keep other programs on the other processor. SMP Seesaw provides a means to do this.

Note: SMP Seesaw is entirely useless if you don't have a dual processor system or don't use Windows NT 4.0 / 2000. Currently it does not support quad or even more insane systems.
