The NIH Biowulf cluster is a Linux parallel processing system designed and built at the National Institutes of Health. Managed by the Helix Systems Staff, Biowulf consists of a main login/administrative node and 1850+ compute nodes (4800+ processors) running the GNU/Linux operating system.

Accounts on the Biowulf cluster are available to all NIH scientists who have a need for large-scale computational resources.
