The NHSE seeks to actively promote software sharing and reuse within and across the HPCC agency programs on a sustainable basis. There are twelve participating agencies in the federal HPCC program. The NHSE facilitates the development of discipline-oriented software and document repositories and promotes contributions and use via the World Wide Web.

Development of the NHSE is being carried out by the Center for Research on Parallel Computation (CRPC). The NHSE, which was formed in 1994, is operating in the final year of a five year federal grant.
