Computational Infrastructure for the Community Surface Dynamics Modeling System

社区表面动力学模拟系统(CSDMS)支持对地球表面过程进行模拟的不同专家社区。它通过开发、支持和传播综合软件模块来预测流体的运动，以及地貌及其沉积盆地中沉积物和溶质的通量(生产、侵蚀、运输和沉积)。目前的CSDMS建模框架将扩展为在网络浏览器、更广泛的计算平台和其他高性能计算集群上使用，以确保框架的健壮性和可持续性。社区生成的模型将转换为即插即用？通过开发组件自动包装工具。将采用量化模型不确定性的方法。基准数据将被纳入CSDMS建模框架，以支持模型间比较。最后，还将在建模框架内开发用于吸收和利用语义中介数据库的健壮机制。为了开发CSDMS架构和协议与临界区天文台开发的模型和数据之间的兼容性，CSDMS简化了无数与社会相关的过程的计算机模拟，包括冰川融化、滑坡、侵蚀、湿地演变、水循环、洪水和海岸变化。通过其社区支持机制，CSDMS催化了想法生成和假设测试的过程，使快速创建和应用针对特定环境、科学问题和时间尺度的模型成为可能。CSDMS？社区方法允许高效地开发比任何单个团队开发的模型更强大的模型？冗余减少了，模型得到了更好的审查，创新能力得到了扩大，能源可以集中到没有得到很好代表或有争议的地球表面领域。CSDMS通过征求和发布模型文档来确保模型是可访问和透明的。CSDMS集成设施的工作人员将模型转换为易于耦合在一起的模块；这种模块化为现有软件带来了新的应用程序。

The Community Surface Dynamics Modeling System (CSDMS) supports a diverse community of experts who model Earth surface processes. It does so by developing, supporting, and disseminating integrated software modules that predict the movement of fluids, and the flux (production, erosion, transport, and deposition) of sediment and solutes in landscapes and their sedimentary basins. CSDMS provides open-access to numerical models, maintains data for modelers and educational resources on earth science modeling for teachers, provides computing resources for members, offers help in advanced model coupling, and is a platform of discussion for earth science research.This project aims to enhance the CSDMS cyber-infrastructure. The current CSDMS Modeling Framework will be extended for use within a web browser, on a wider variety of computational platforms, and on other high performance computing clusters to ensure robustness and sustainability of the framework. Community-generated models will be converted into ?plug-and-play? components through the development of automated wrapping tools. Methods for quantifying model uncertainty will be adapted. Benchmarking data will be incorporated into the CSDMS modeling framework to support model inter-comparison. Finally, a robust mechanism for ingesting and utilizing semantic mediation databases will also be developed within the Modeling Framework. In addition, six new community initiatives will be pursued: 1) an Earth - ecosystem modeling initiative to capture ecosystem dynamics and ensuing interactions with landscapes, 2) a geodynamics initiative to investigate the interplay among climate, geomorphology, and tectonic processes, 3) an Anthropocene modeling initiative, to incorporate mechanistic models of human influences, 4) a coastal vulnerability modeling initiative, with emphasis on deltas and their multiple threats and stressors, 5) a continental margin modeling initiative, to capture extreme oceanic and atmospheric events generating turbidity currents in the Gulf of Mexico, and 6) a CZO Focus Research Group, to develop compatibility between CSDMS architecture and protocols and Critical Zone Observatory-developed models and data.CSDMS streamlines the computer modeling of myriad societally relevant processes, including melting glaciers, landslides, erosion, wetland evolution, water cycling, flooding, and coastal change. Through its community support mechanisms, CSDMS catalyzes the process of idea generation and hypothesis testing, enabling the rapid creation and application of models tailored to specific settings, scientific problems, and time scales. CSDMS? community approach allows the efficient development of models that are more powerful than could be developed by any single group ? redundancy is reduced, models are better vetted, the capability for innovation is expanded, and energy can be focused towards earth-surface domains that are poorly represented or controversial. CSDMS ensures that models are accessible and transparent by soliciting and publishing model documentation. Staff at the CSDMS Integration Facility convert models into modules that can be easily coupled together; this modularity gives rise to new applications for existing software. This new award will enable CSDMS to enhance its cyber-infrastructure by developing: 1) software products and approaches designed to be accessible, easy to use, and relevant, 2) new community initiatives to advance earth-surface process modeling across many disciplines, and 3) educational products and training workshops aimed at various entry levels.
