DME: a distributed matrix environment

The paper describes DME, a distributed matrix environment for creating and manipulating sparse matrices on distributed-memory multiprocessors. The goals of this environment are: to define a distributed sparse matrix representation scheme that can serve as a platform for building a range of important matrix operations; to provide a clean, consistent way for parallel applications to build distributed matrices; and to provide a tool-kit of utility routines for common distributed matrix operations. The paper describes the design philosophy behind DME, the DME distributed sparse matrix representation scheme, the mechanisms for creating and modifying these matrices, and the set of matrix utilities DME provides.<<ETX>>
