PrairieFire
PrairieFire is a 90-node Beowulf cluster, originally constructed in 2002. It originally scored an HPL benchmark number of 442.50 GFlops, which was then the 107th most powerful supercomputer in the world, according to the TOP500 supercomputer list.
PrairieFire was substantially upgraded through an NSF/MRI (Major Research Instrumentation) grant in cooperation with the Water Resources Research Initiative (WRRI) and UNL's Office of Research.
PrairieFire is used by scientists and engineers to study subjects such as nanoscale chemistry, subatomic physics, meteorology, genomics, crashworthiness and artificial intelligence. PrairieFire is also used by students at the University of Nebraska-Lincoln for several courses each year.
