Development of a New Dynamical Core for the Unified Model: Portable, Scalable Performance

编写好的计算机程序，模拟复杂的现象，如天气和气候变化，在最快的计算机上运行，是必要的，这样才能使科学调查尽可能快地进行。新代码的开发需要几个不同领域的专家合作：科学家必须开发数学模型，以提供所需的科学见解，算法开发人员必须将模型转化为一步一步的程序，使模型能够应用于特定问题（从今天计算明天的天气，或预测一百年后的气候）。最后，算法必须用一种编程语言编码，使计算机能够为科学家进行计算。计算机的速度越来越快，用于构建计算机的技术也在不断变化，这给算法和程序开发人员带来了新的挑战。该项目汇集了来自各个专业领域的专家，他们将共同努力，创造下一代天气和气候模拟的关键组件，即动力核心，它基本上是模拟大气中空气的运动。我们对这项工作的贡献是帮助确保开发的算法可以有效地编程，以便在今天的计算机上运行，并且可以很容易地转移到未来的计算机上，尽管硬件技术发生了变化。

Writing good computer programs that model complex phenomena, such as the weather and climate change, to run on the fastest computers is necessary to allow scientific investigation to proceed as rapidly as possible. The development of new codes involves experts in several different areas to cooperate: the scientist has to has to develop the mathematical model that will provide the desired scientific insights, algorithm developers have to turn the model into a step-by-step procedure which enables the model to be applied to a particular problem (calculating tomorrows weather from today's, or predicting the climate in a hundred years time). Finally, the algorithm has to be coded in a programming language that enables a computer to do the calculations for the scientist. Computers continue to get faster, and the technology used to build them is constantly changing, leading to new challenges for algorithm and program developers. This project brings together experts from each of the areas of expertise who will work together to create the next generation of a key component in weather and climate simulation, the dynamical core, which, basically, models the movement of air in the atmosphere. Our contribution to this effort is to help make sure that the algorithms developed can be efficiently programmed for running on today's computers and be easily moved to future computers, despite changes in hardware technology.
