 More than 700 computers were brought to the gym at the University of San Francisco, and were wired to a network donated by Foundry Networks.At FlashMob I the participants were able to run a benchmark on 256 of the computers, and achieved a peak rate of 180 Gflops (billions of calculations per second), though this computation stopped three quarters of the way due to a node failure.The best, complete run used 150 computers and resulted in 77 Gflops.
