ARP 重新启动的最新情况

在 2022 年 12 月项目暂停后,ARP 团队正准备重新启动该项目。本文概述了我们为重启该项目所采取的步骤。

项目: 非洲降雨项目

发布于: 25 四月 2024

项目背景

非洲降雨项目(ARP)旨在模拟撒哈拉以南非洲地区的暴雨,以改进地区天气预报。其目标是对整个地区进行为期一年的高分辨率(1 公里)天气模拟。提供准确的天气预报对当地农业社区的自给自足至关重要。通过比较利用世界社区网格计算不同来源降雨量数据所获得的结果,科学家们可以做出越来越准确的预测,改进未来的模拟,进而改进天气预报。如需了解该项目的更多信息,请参阅我们 2022 年 3 月的研究更新。

2022 年 12 月,由于存储系统容量有限,该项目暂停。有关存储限制的详细信息,请参阅 2023 年 3 月的 ARP 更新。正如我们在 2023 年 7 月的更新中所分享的,这一挑战的部分原因是 ARP 团队从荷兰教育和研究机构合作协会 SURF 获得的存储支持终止了。幸运的是,亚马逊网络服务公司(AWS)同意托管数据,从而开始了数据迁移过程。搬迁完成后,ARP 团队一直在采取措施,以便通过 AWS 平台更广泛地访问数据,但这项工作仍处于早期阶段。目前,工作重点是完成新工作单元的准备工作,并生成重启 ARP 所需的数据。

ARP 重启更新

我们已开始着手恢复向志愿者发送 ARP1 工作单元。我们在代尔夫特理工大学(TU Delft)的研究合作伙伴已经向我们发送了大部分所需的脚本和文档,我们已对其进行了审查并在本地实施。目前,我们正在等待决定是直接接收所需的其余数据和应用代码,还是需要根据代尔夫特理工大学团队提供的文档复制这些组件。经过评估,我们认为这两种方法都是可行的,并希望让志愿者们知道,我们已经确定了在未来几周内重启 ARP1 的路径。


重启该项目的时间表取决于 ARP 团队提供的信息。如果所需的代码和数据不能完全提供给我们,我们将需要建立生成新 ARP1 工作的管道的缺失部分,并确认我们能够重现之前从代尔夫特理工大学服务器收到的相同输入,以验证新管道。无论如何,志愿者不需要做出任何改变和行动来促进这一过程,当 ARP1 重新启动时,工作单元的分配将与之前相同。

感谢 ARP 团队与 WCG 的持续合作。如果您有任何问题或意见,请在此主题中留下,以便我们回答。

ARP restart update

The ARP team is preparing to restart after the project was put on pause in December 2022. This article outlines the steps that we are taking in order to restart this project.

Project: Africa Rainfall Project

Published on: 25 四月 2024

Background

The Africa Rainfall Project (ARP) aims to simulate rainstorms in sub-Saharan Africa to improve regional weather forecasts. The goal is to run a weather simulation at a high resolution (1 km) for the whole region for a period of one year. Providing accurate weather predictions is crucial for self-sufficiency of the local farming community. By comparing results obtained through computing rainfall data from various sources using the World Community Grid, scientists can create increasingly more accurate forecasts, improve future simulations and in turn weather predictions. To read more about this project, see our March 2022 research update.

In December 2022, the project was put on pause due to capacity limitations of their storage system. To read more about the details of this storage limitation, please refer to ARP update from March 2023. As we shared in a July 2023 update, part of this challenge was that the ARP team’s storage support from SURF, the cooperative association of Dutch educational and research institutions, came to an end. Fortunately, Amazon Web Services (AWS) agreed to host the data, and thus began the process of moving the data. Since the move is complete, the ARP team has been taking steps to make the data more broadly accessible through the AWS platform, but this work is still in the early stages. Currently, the focus is on finalizing the preparation of new work units and generating the data needed to restart ARP.

ARP Restart Update

We have started to work on resuming sending out ARP1 work units to volunteers. Our research partners at TU Delft have already sent us most of the required scripts and documentation, which we have reviewed and implemented locally. Currently, we are awaiting a determination on whether we will receive the rest of the required data and application code directly, or whether we will need to reproduce these components from documentation provided by the TU Delft team. We have assessed that both approaches are feasible, and wanted to let volunteers know that we are on a defined path to restarting ARP1 in the coming weeks.


The timeline of a possible restart of this project depends on the information from the ARP team. If the code and data required is not fully available to us, we will need to build out the missing components of the pipeline for generating new ARP1 work and confirm that we are able to reproduce the same inputs as we previously received from TU Delft servers to validate the new pipeline. Regardless, there will be no change and no action required by volunteers to facilitate the process and when ARP1 restarts work unit distribution will be the same as before.

Thanks to the ARP team for their continued partnership with the WCG. If you have any questions or comments, please leave them in this thread for us to answer.
