Iterative methods for solving linear systems arising from the differencing of partial differential equations require the use of pre-conditioners to gain increased rates of convergence. Preconditioners arising from incomplete factorizations have been shown to be very effective. However, the recursiveness of these methods can offset these gains somewhat on a parallel processor. In this paper, an incomplete factorization using odd-even shuffles is developed and compared to other methods.
