Dec 17, 2008 by Paul White

Task Manager at 100 percent on core i7Now that you have your awesome new core i7 workstation ( like me ), its a shame that whenever you look at task manager you rarely see your 8 processing threads being utilized.  Well if you are one of those people that prefer your 4 cores not being hanging around the water cooler all day ( System Idle Process ). Then I have just the program for you.  Help in the Search for Extraterrestrial Intelligence ( SETI )

It works so well I was able to cancel my account with postini.
