Scientific Supercomputing at the NIH
The Helix Systems group is responsible for the planning and management of high-performance computing systems specifically for the intramural NIH community. These systems include Helix, a multiprocessor shared-memory system for interactive use; Biowulf, a 6300+ processor Linux cluster; and Helixweb, which provides a number of scientific tools via the web. We provide access to a wide range of computational applications for molecular and structural biology, mathematical and graphical analysis, and other scientific fields.
