The fastest Mac supercomputer has gotten faster, thanks to an Xserve makeover.

Virginia Tech plans to announce on Tuesday that its System X now operates at 12.25 teraflops, or 12 trillion calculations per second, up from 10.28 teraflops in its original incarnation, which used 1,100 Power Mac G5 towers. The performance boost comes in large part because Apple Computer has made available to Virginia Tech custom 2.3GHz Xserve machines, which are faster than the 2GHz processors that power Apple's fastest machines. The school also added 50 additional servers, or nodes, to the system.
