We investigate the use of sparse approximate inverse techniques in a multi-level block ILU preconditioner to design a robust and eecient parallelizable preconditioner for solving general sparse matrices. The resulting preconditioner retains robustness of the multi-level block ILU preconditioner (BILUM) and ooers a new way to control the ll-in elements when… CONTINUE READING
