报告简介:
        Projected from today, exascale computers are characterized by billion way parallelism. Computing on such extreme scale needs methods wi-th perfect scaling and optimal complexity. The solver itself must be ?of optimal numerical complexity a requirement becoming more and ?more severe with increasing problem size and scale efficiently on ex-treme scales of parallelism.We will present a multigrid approach scali-ng efficiently unto the full size of the largest computers available andlooks promising for even larger scales. We further show that robuste-ss can be maintained during the scaling process for relevant applicati-on problems while still maintaining optimal complexity.
