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.

编写好的计算机程序来模拟复杂的现象，如天气和气候变化，以便在速度最快的计算机上运行，对于允许科学调查尽可能快地进行是必要的。新代码的开发需要几个不同领域的专家合作：科学家必须开发提供所需科学见解的数学模型，算法开发人员必须将模型转变为循序渐进的过程，使模型能够应用于特定问题(根据今天的天气计算明天的天气，或预测100年后的气候)。最后，算法必须用一种编程语言编写，使计算机能够为科学家进行计算。计算机继续变得更快，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中的关键组件--动力核心，它基本上是对大气中的空气运动进行建模。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，并可以轻松地移植到未来的计算机上，尽管硬件技术发生了变化。
