OpenGeoModeller

介绍

地球科学模拟有很多Awesome项目,本仓库建立地球科学模式的工作流,包含:区域性气象模式、地表水、地下水、地震波正演等数学模式,以及相应的前后处理程序。

选择HPC应用程序的思考维度包括: (1) 前沿的数值算法; (2) 并行模式和计算效率; (3) 模型的工业级应用能力; (4) 可迁移性(可应用于不同架构的处理器)。

即:Performance-Productivity-Portability

仓库架构如下图,目的是将地球科学模拟统一在一个框架下,主要就是前处理、编译运行和后处理可视化 仓库架构

学习路线

工程流体力学 -> CFD基础算法 -> 计算机辅助设计(CAD) -> 高性能计算基座 -> 地球科学的awesome项目 -> 海洋模拟 -> Geosciences-for-the-Future -> Geosciences for the Future
