Abstract :
The authors present a new approach to preconditioning for very large, sparse, non-symmetric, linear systems. It explicitly computes an approximate inverse to the original matrix that can be applied most efficiently for iterative methods on massively parallel machines. The algorithm and its implementation on the Connection Machine CM-2 are discussed in detail and supported by timings obtained from real problem data
