With the advent of multiple CPU cores, software - particularly Operating systems - need to be aware of additional core and how to utilize them efficiently. Windows does a fine job at it. However, it doesn't give the user much control over it other than allowing a basic processor affinity allotment.

But then again why would a user want to look into the nitty-gritty's of processor usage? Well because God's in the details! Most users do not need to look into how a system manages process priorities and core usage but experts/technically inclined users (read geeks) will really appreciate the minute control that one can have over the cores.

Today's application that I'm referring to is a real smart one called Process Lasso. Process Lasso is specifically designed to let you harness all the processes running in the system to avoid unpleasant bottleneck situations. Its main purpose is to enable computer responsiveness and lets the user create specific rules for all the processes running on the computer leading to much better system responsiveness.
