GPU Preconditioning for Block Linear Systems Using Block Incomplete Sparse Approximate Inverses
Solving sparse triangular systems is the building block for incomplete LU- (ILU-) based preconditioning, but parallel algorithms, such as the level-scheduling scheme, are sometimes limited by available parallelism extracted from the sparsity pattern. In this study, the block version of the incomplet...
