Gigaflops in Linear Programming
Irvin J. Lustig and Edward Rothberg
This paper describes the parallelization of an ``industrial strength''
linear programming package. Our parallel version of CPLEX barrier,
running on a Silicon Graphics Power Challenge shared-memory
multiprocessor, provides dramatic performance improvements over
sequential methods on a wide range of practical, realistic linear
programming problems. The resulting software/hardware combination can
provide sustained performance of as much as 2 Gflops.
