Abstract:

In this paper, the basic Simplex algorithm is reexamined. Computational steps which can be done in parallel are identified, and a parallel version of the Simplex method is implemented on the Flex/32, a multiprocessors computer. Medium to large scale examples are used to demonstrate the effectiveness of the proposed algorithm. Numerical results show that a speed up factor of more than 12 can be obtained by using the proposed parallel Simplex method on the Flex/32 computer.
