第二批：新的天气和气候矮人的定义
Batch 2: Definition of novel Weather & Climate Dwarfs
摘要：
本文档是为ESCAPE项目创建的可交付成果报告之一。ESCAPE是Energy-efficient Scalable Algorithms for Weather Prediction at Exascale的缩写。该项目为欧洲业务数值天气预报和未来气候模型开发世界级的极端规模计算能力。这是通过识别天气和气候侏儒来完成的，这些侏儒是计算和通信方面的关键模式（本着伯克利侏儒的精神）。然后针对不同的硬件架构（单节点和多节点）优化这些侏儒，并探索替代算法。性能可移植性是通过使用领域特定的语言来解决的。该交付成果包含对第二组所谓的数值天气和气候预测侏儒的特征的描述，这些侏儒在其封装的科学方面以及在其对预测产品施加的计算成本方面构成了预测模型的关键功能组件。工作包之间的ESCAPE工作流以这些小矮人为中心，因此它们的选择，性能评估，代码适应和优化对于项目的成功至关重要。选择这些新的矮星的目的是为了扩展先前在第一批中选择的矮星所代表的计算特性的范围（见表D1.1）。小矮人已经制造出来，它们的文档已经汇编，软件已经在软件交换平台上提供。在这个交付的侏儒包括一个多重网格椭圆求解器，一个新的非结构化网格的平流方案，一个结构化网格的平流方案和辐射计划。该交付件包括其科学描述以及安装、执行和测试指南。
英文摘要：
This document is one of the deliverable reports created for the ESCAPE project. ESCAPE stands for Energy-efficient Scalable Algorithms for Weather Prediction at Exascale. The project develops world-class, extreme-scale computing capabilities for European operational numerical weather prediction and future climate models. This is done by identifying weather & climate dwarfs which are key patterns in terms of computation and communication (in the spirit of the Berkeley dwarfs). These dwarfs are then optimised for different hardware architectures (single and multi-node) and alternative algorithms are explored. Performance portability is addressed through the use of domain specific languages. This deliverable contains the description of the characteristics of a second set of so-called numerical weather & climate prediction dwarfs that form key functional components of prediction models in terms of the science that they encapsulate and in terms of computational cost they impose on the forecast production. The ESCAPE work flow between work packages centres on these dwarfs and hence their selection, their performance assessment, code adaptation and optimisation is crucial for the success of the project. These new dwarfs have been chosen with the purpose of extending the range of computational characteristic represented by the dwarfs previously selected in batch 1 (see Deliverable D1.1). The dwarfs have been made, their documentation has been compiled and the software has been made available on the software exchange platform. The dwarfs in this deliverable include a multigrid elliptic solver, a novel advection scheme for unstructured meshes, an advection scheme for structured meshes and a radiation scheme. This deliverable includes their scientific description and the guidance for installation, execution and testing.
