The NIH HPC group plans, manages and supports high-performance computing systems specifically for use by the intramural NIH community. These systems include Biowulf, a 105,000+ processor Linux cluster; Helix, an interactive system for file transfer and management, and Helixweb, which provides a number of web-based scientific tools. We provide access to a wide range of computational applications for genomics, molecular and structural biology, mathematical and graphical analysis, image analysis, and other scientific fields.

The continued growth and support of NIH's Biowulf cluster is dependent upon its demonstrable value to the NIH Intramural Research Program. If you publish research that involved significant use of Biowulf, please cite the cluster. Suggested citation text:
