Virginia Tech's Mac Pro supercomputer to crack 29 teraflops
A switch to newer Intel-based Apple Mac Pro workstations for an upcoming rekindling of Virginia Tech's supercomputer efforts will more than double the performance to as much as 29 teraflops and will once again put a Mac cluster in the limelight -- this time, placing it among the top 100 supercomputers in the world.
When it's completed in the next several weeks, the new project discussed with Ars Technica will rely on 324 eight-core, 2.8GHz Mac Pro towers to achieve the result, joining them across a quad-speed InfiniBand link that offers three times as much room for network traffic as the original model, dubbed System X.
Although the school is using just a third of the computers found in the earlier cluster, which at its peak has used 1,150 Xserve G5s, the fresh cluster will have a total of 2,592 cores that individually operate faster than each of the 2,200 PowerPC chips found in the older rackmount computers. The old system at most processed 12.25 teraflops and itself eclipsed the original System X, based on 1,100 PowerMac G5s.
