This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The goal of our interdisciplinary e ort between computational scientists, physicists, engineers and applied mathematicians is to build an all{scales unified simulation system that can exploit the next generation of petascale systems and beyond. The advances proposed herein hold the potential of greatly enhanc-ing possible breakthroughs in various research disciplines involved with continuum mechanics. Specifically, the novelties will include: high-order discontinuous Galerkin methods with simultaneous adaptive h-p unstructured non-conforming meshes, multi-methods for time integration including multirate, implicit-explicit(IMEX), strong-stability preserving (SSP), exponential integrators, Parareal time-integration, adjoint-based error estimates, and new optimal iterative solvers. These ideas will ultimately be targeted for use on a deep atmosphere and ocean model.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。我们计算科学家、物理学家、工程师和应用数学家之间的跨学科努力的目标是建立一个全尺度统一模拟系统，可以利用下一代千万级系统及更高级别的系统。本文提出的进展具有极大增强涉及连续介质力学的各个研究学科可能突破的潜力。具体来说，新颖之处包括：具有同时自适应 h-p 非结构化非一致性网格的高阶不连续 Galerkin 方法、多种时间积分方法，包括多速率、隐式-显式 (IMEX)、强稳定性保持 (SSP)、指数积分器、准实时时间积分、基于伴随的误差估计和新的最优迭代求解器。这些想法最终将用于深层大气和海洋模型。
