Parallel Preconditioning and Approximate Inverses on the Connection Machine

13 years 7 months ago

Download www.nersc.gov

We present a new approach to preconditioning for very large, sparse, non-symmetric, linear systems. We explicitly compute an approximate inverse to our original matrix that can be...
