Apple Xgrid... Imagine waking up one day to find your Mac has solved a vexing scientific problem. While the cure to cancer, super-efficient solar power and ending world hunger are a ways off, you can combine your computing resources using Xgrid Ñ and help usher in a new era of biological breakthroughs, rocket science and advanced models of scientific phenomena.

Xgrid turns a group of Macs into a supercomputer, so they can work on problems greater than each individually could solve. You can let Xgrid operate in screensaver mode, so whenever you arenÕt working, your Mac can crunch away at some data set. Or if you have a group of Macs dedicated to the task, Xgrid makes it easy to set up a cluster that works around the clock, every day of the year.

Without needing any programming knowledge, you can see the power of sharing resources when you set a group of Macs to drawing sophisticated graphics. As you add more Macs to the cluster, the program draws more quickly, as in the included Mandelbrot set demo. If youÕre a geneticist, youÕll appreciate the Xgrid BLAST application that lets you compare sets of genetic sequences even more quickly.

Xgrid uses zero configuration Rendezvous to discover available resources, so you never have to enter IP addresses to set up a cluster. An easy-to-use System Preference panel lets you control how your machine gets used by the network, and also tells the cluster which computer can send problems to the group for number crunching. Xgrid takes the grunt work out of splitting jobs and collecting results. Many scientists who already use command line tools in their work will immediately be able to take advantage of Xgrid and have the power of a cluster without the hassle of setup.
