The Firefly computer is a high-performance computer cluster housed at the Holland Computing Center located inside of the Peter Kiewit Institute at the University of Nebraska Omaha.[citation needed]
The system runs on 1,151 compute nodes, 871 have quad-core AMD Opteron processors and 280 have dual quad-core processors. All have eight gigabytes of memory.[1] Each node is connected to a high-speed, low-latency InfiniBand fabric.[2]
The supercomputer ranked 43 of 500 in the Top 500 Supercomputing Sites list in November 2007[3][4] but has since dropped out of the top 500 since the Center's rating was not updated after upgrades.[5]
