Abstract

We present 3LM, a C Linked List Management Library for parallel sparse factorizations on a PVM environment which takes into account the fill-in, an important drawback of sparse computations. It is restricted to a mesh topology and is based on an SPMD paradigm. Our goal is to facilitate the programming in such environments by means of a set of list and vector-oriented operations. The result is a pseudo-sequential code, in which the interprocessor communications and the sparse data structures are hidden from the programmer.
