Apple's Xserve has achieved a new benchmark, according to developer Dauger Research.

The Applied Cluster Computing group at NASA's Jet Propulsion Laboratory has used a parallel-processing cluster of 33 Xserves to achieve over 217 billion floating point operations per second, MacCentral reports. The developers claim its the largest working Xserve cluster ever.

The cluster Xserves operating at 1GHz were running Mac OS X Server 10.2, and performed the computation using Danger Research's Pooch software.

Pooch is cluster-management software for creating high-performance parallel computers. It combines both multiprocessor and cluster computing. More information on the product is available from the company's Web site.
