Say you need some additional firepower to play the latest online shooter with maximum fps, and decide to assign three of the four cores of your Intel Quad Core CPU to that single application and run the rest of the applications on the remaining cpu core.
That's a valid scenario don't you think? It does not have to be a game though, you could assign a cpu intense application to a core and the rest of the applications to another.
SMP Seesaw is the application that you are looking for if you want to control cpu core use in detail. It's probably more of a tool for users who have the time to optimize their computers in that area, to test how they can squeeze another frame out of the box by assigning applications perfectly to the cpu cores of the processor.
The software comes in two versions, a regular and pro version. Both are free surprisingly and the difference lies in the detail. The pro version can manage up to 32 CPU cores while the regular version handles dual core systems only.
The pro version has two additional features that are missing in the regular version; It can control processor affinities for system services and provides a programmatic interface for C/C++, Visual Basic and Windows Scripting Host among other programming languages.
SMP Seesaw is Open Source and I think it's interesting that this application has a size of only 100 Kilobyte.
At start of the regular SPM Seesaw that supports two core CPUs all current processes are listed in the middle which means that they are assigned to be run by both cpu cores. They can then be moved to a single cpu or isolated on a cpu.
SMP Seesaw is no longer in active development. You can use a program like Process Lasso instead which is still in active development.
