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 at Omaha.
The system originally ran on 1,151 compute nodes, each of which had two dual-core processors with four gigabytes of memory. Each node is connected to a high-speed, low-latency Infiniband fabric. Later, the processors were upgraded to Quad-Core AMD Opteron processors. This boosted the Center's rating from 21.5 TeraFLOPS to roughly 60 TeraFLOPS and brought the total number of cores to 9,200.[1]
The supercomputer ranked 43 of 500 in the Top 500 Supercomputing Sites list in November 2007[2] but has since dropped out of the top 500 since the Center's rating was not updated after their upgrade.[3]
