A parallel algorithm for large-scale linear programs with a special structure

A new sequential algorithm and computational results for large-scale linear programs with a special structure were presented previously by J.B. Rosen and S. Oh (1992). A parallel version of the algorithm is developed for a hypercube multiprocessor architecture NCUBE2. Computational results using 128 processors are presented for a randomly generated large-scale sparse or dense problems with the number of variables up to 256 and constraints up to 5 million.<
