我们开发了一种新的分析能力，供科学家和工程师从运行在数千个处理器上的大规模并行非结构网格模拟中获得洞察力。这一突破是通过一种新的方法实现的，该方法在并行偏微分方程组(PDE)解算器执行时同时可视化偏微分方程(PDE)解数据。解场直接流水线到体绘制，体绘制是使用求解PDE方程的相同处理器并行计算的。由于我们的方法避免了与传输和存储大量输出数据相关的瓶颈，它为克服PB级模拟的可视化挑战提供了一种很有前途的方法。提交的视频演示了从远程笔记本电脑对1994年南加州北岭地震的1024处理器模拟进行实时动态监控、解释和驾驶。
We have developed a novel analytic capability for scientists and engineers to obtain insight from ongoing large-scale parallel unstructured mesh simulations running on thousands of processors. The breakthrough is made possible by a new approach that visualizes partial differential equation (PDE) solution data simultaneously while a parallel PDE solver executes. The solution field is pipelined directly to volume rendering, which is computed in parallel using the same processors that solve the PDE equations. Because our approach avoids the bottlenecks associated with transferring and storing large volumes of output data, it offers a promising approach to overcoming the challenges of visualization of petascale simulations. The submitted video demonstrates real-time on-the-fly monitoring, interpreting, and steering from a remote laptop computer of a 1024-processor simulation of the 1994 Northridge earthquake in Southern California.
