Parallel computing at the AMNH has a nineteen-year history, beginning with homebrew clusters assembled by curators and graduate students. Today the facility consists two Intel multi-node Linux based machines, a 40-processor Sun Ultrasparc III machine, and an eight-processor AMD Opteron server, which have collectively been in service for five years. The compute clusters are used intensively for research that relies heavily on high-end capability computing in comparative biology, genomics, astrophysics, and anthropology.
