“…By generating a denser preconditioner, SAI preconditioning can reduce iterations in iterative solvers considerably and be applied to a broad range of applications. Previous work has accelerated the computation of this preconditioner on multiple processors [5], [6], [7], [8], [9], [10], [11], [12], [13] as well as multicore [14], [15] and manycore architecture [16].…”
