IceCube 将数据传输从 GridFTP 迁移至 Pelican 平台，通过定制 WLCG 令牌颁发器和 HTCondor 修改，解决了存储与作业提交问题，并证明新系统更优。
中文摘要 AI 辅助
IceCube 中微子天文台已移除用于数据传输的 GridFTP 和 x.509 证书认证，迁移至 Pelican 平台、开放科学数据联盟（Open Science Data Federation）和 WLCG 令牌。虽然这是我们使用的计算基础设施中的常见解决方案，但我们需要进行多项定制，以适配我们现有的数据存储结构，并方便科学家使用。我们编写了一个自定义的 WLCG 令牌颁发器，以支持我们整个文件系统上具有自定义用户和组权限的 POSIX 文件系统。我们还对 HTCondor 进行了多项修改，以简化使用令牌提交作业，包括一个自定义的 credmon。在经历了一段因若干现已解决的 Pelican 问题而导致的初期波折后，基于 Pelican 的系统已在多个方面被证明优于 GridFTP。
英文摘要
The IceCube Neutrino Observatory has removed GridFTP and x.509 certificate authentication for data transfers, migrating to the Pelican Platform, the Open Science Data Federation, and WLGC tokens. While this is a common solution on the computing infrastructure we use, we required several customizations to work with our existing data storage structure and make it easier for scientists to use. We wrote a custom WLCG token issuer to support our POSIX filesystem with custom user and group permissions across the entire filesystem. We also made several modifications to HTCondor to ease job submission using tokens, including a custom credmon. After an initially bumpy transition due to several now-resolved Pelican issues, the Pelican-based system has already proven superior to GridFTP in several ways.
