SI2-SSI: Collaborative Research: Building Sustainable Tools and Collaboration for Volcanic and Related Hazards

该项目的重点是为从事火山学研究和相关危害分析的大型科学家社区创建和升级软件基础设施。具体而言，该项目将重新设计三种广泛使用的工具（TITAN2D -块和火山灰流，TEPHRA和Puff -火山灰运输和分散），并开发使用这些工具分析火山灾害风险的工作流程支持。再工程将包括模块化，这样研究人员可以很容易地试验不同的建模方法，结合技术，使工具在新的计算架构上高效，如gpu和多核芯片。工作流旨在处理管理与这些工具在验证过程和基于建模结果的概率推断中相关的复杂且通常较大的数据流的挑战。这些工具和工作流将通过流行的vhub.org平台提供。该项目将有助于提供一个标准的、管理良好的硬件/软件平台，以及标准化与输入数据、源代码和输出数据相关的文档的方法。这将确保模型计算是可重复的。这些高保真度工具的广泛使用及其在减轻危害方面的使用可能对危害分析和管理产生重大影响。该项目还将参加几个大型讲习班和培训活动。项目人员还将参与Earthcube倡议——通过VHub平台普及计算方法、在线访问和传播机制。

This project is focused on creating and upgrading software infrastructure for a large community of scientists engaged in volcanology research and associated hazard analysis. Specifically, the project will reengineer three widely used tools (TITAN2D - block and ash flows, TEPHRA and Puff - ash transport and dispersal) and develop support for workflows that use these tools to analyze risk from volcanic hazards. Reengineering will encompass modularization so researchers may easily experiment with different modeling approaches, incorporation of techniques to make the tools efficient on new computing architectures like GPUs and many-core chips. The workflows are intended to tackle the challenges of managing complex and often large data flows associated with these tools in validation processes and in probabilistic inference based on the outcomes of the modeling. The tools and workflows will be made available using the popular vhub.org platform. This project will help provide a standard well managed hardware/software platform and approaches to standardize the documentation associated with input data, source code, and output data. This will ensure that model calculations are reproducible.The wider use of these high fidelity tools and their use in mitigating hazards is likely to have a significant effect on hazard analysis and management. The project will also engage in several major workshops and in training activities. Project personnel will also engage in the Earthcube initiative - popularizing computational methodologies, online access and dissemination mechanisms through the VHub platform.
