An efficient parallel implementation of the MSPAI preconditioner

13 years 6 months ago

We present an efficient implementation of the Modified SParse Approximate Inverse (MSPAI) preconditioner. MSPAI generalizes the class of preconditioners based on Frobenius norm mi...

Parallel Multilevel Sparse Approximate Inverse Preconditioners in Large Sparse Matrix Computations

14 years 4 months ago

Download www.sc-conference.org

We investigate the use of the multistep successive preconditioning strategies (MSP) to construct a class of parallel multilevel sparse approximate inverse (SAI) preconditioners. W...
