The "Big Mac" is a cluster of 1,100 dual-processor Apple G5 Power Macintosh computers. It is notable for its relatively low cost of just over 5 million dollars and high power (9.55 teraflops) as well as its short build time of about six months. The Terascale Cluster has a good price-performance ratio. It falls only behind Japan's Earth Simulator (35.8 teraflops) and the ASCI Q supercomputer (13.8 teraflops) in raw power.
Srinidhi Varadarajan believes that further tuning could boost performance by another 10 percent.
