Digital Software and Data Repositories for Support of Scientiic Computing

This paper discusses the special characteristics and needs of software repositories and describes how these needs have been met by some existing repositories. These repositories include Netlib, the National HPCC Software Exchange, and the GAMS Virtual Repository. We also describe some systems that provide on-line access to various types of scienti c data. Finally, we outline a proposal for integrating software and data repositories into the world of digital document libraries, in particular CNRI's ARPA-sponsored Digital Library project. The work described in this paper was sponsored by NASA under Grant No. NAG 52736, by the National Science Foundation under Grant No. ASC-9103853, and by AT&T Bell Laboratories.
