We investigate different methods for computing a sparse approximate inverse M for a given sparse matrix A by minimizing AM -E in the Frobenius norm. Such methods are very useful for deriving preconditioners in iterative solvers, especially in a parallel environment. We compare different strategies f
We dedicate this paper to Henk van der Vorst, for his friendship, inspiration, and leadership in numerical linear algebra and numerical algorithm development, on the occasion of his 65th birthday.
We investigate the use of sparse approximate inverse techniques in a multilevel block ILU preconditioner to design a robust and efficient parallelizable preconditioner for solving general sparse matrices. The resulting preconditioner retains robustness of the multilevel block ILU preconditioner (BIL
