System G

Contact: Kirk Cameron

The System G cluster consists of 324 Mac Pros, each with two 4-core 2.8 GHz Intel Xeon processors (for a total of 2592 processor cores) and eight GB of RAM. The system was the first supercomputer running over quad data rate (QDR) InfiniBand (40Gbs) interconnect technology. System G (for "green") also has unique power-aware capabilities, with thousands of power and thermal sensors allowing researchers to design and develop algorithms and systems software that achieve high-performance with modest power requirements, and to test such systems at unprecedented scale. With a sustained (Linpack) performance of 22.8 TFlops, System G is the largest power-aware research system and one of the world's largest clusters dedicated to computer science systems research.
