Chameleon is a deeply reconfigurable experimental testbed supporting Computer Science (CS) systems experimentation. The platform consists of two sites, University of Chicago (UC) and Texas Advanced Computing Center (TACC), along with support functionalities from Northwestern University and the University of North Carolina. the platform balances investment in large-scale hardware to support Big Compute and Big Data experimentation with diversity reflected by smaller clusters of graphic processing units (GPUs), field programmable gate arrays (FPGAs), specialized architectures, and innovative networking hardware. Users can reconfigure this hardware at bare-metal level, boot from custom kernel, get access to serial console, or provision and reconfigure Software Defined Networking (SDN)-enabled switches. Since its public availability in July 2015, Chameleon has attracted a community of over 4,000 users working on over 600 education and research projects.In Phase III, Chameleon will greatly expand its core capabilities by adding new hardware and new features. The range of supported experiments will expand to include Internet of Things (IoT) and edge computing, a broader range of networking experiments, and experimentation with disaggregated hardware. The system will also expand its support for reproducibility by providing tools that allow investigators to package their experiments for replication, and making it possible to publish, discover, and cite them easily. Finally, phase 3 will see a continuation of work on packaging CHameleon Infrastructure, known as CHI-in-a-Box, which allows others to deploy and manage testbeds similar to Chameleon. The Chameleon project will continue its mission of providing a platform for CS research and education in cloud computing, a critical skillset for future computing professionals. Unlike traditional experimental platforms, Chameleon is built on a mainstream open source cloud technology (OpenStack); this not only means that its users and operators gain familiarity with mainstream cloud functions simply by working with the testbed – but also that open source contributions by the Chameleon project directly impact a system widely used in the cloud industry. Finally, through its support of experiment management and repeatability, Chameleon impacts CS experimental methodology and makes more efficient research possible.

For anyone interested in the development side of the system or the packaging of Chameleon, i.e., CHI-in-a-Box, visit the github repository at https://github.com/ChameleonCloud/chi-in-a-box/wiki. If a user would like to explore traces from Chameleon to date, see https://www.scienceclouds.org/cloud-traces/. These sites will be maintained throughout the duration of the project.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

Chameleon 是一个可深度重构的实验测试台，支持计算机科学 (CS) 系统实验。该平台由芝加哥大学 (UC) 和德克萨斯高级计算中心 (TACC) 两个站点组成，并提供西北大学和北卡罗来纳大学的支持功能。该平台平衡了对大规模硬件的投资，以支持大计算和大数据实验，并通过较小的图形处理单元（GPU）集群、现场可编程门阵列（FPGA）、专用架构和创新网络硬件反映出多样性。用户可以在裸机级别重新配置此硬件、从自定义内核启动、访问串行控制台，或者配置和重新配置支持软件定义网络 (SDN) 的交换机。自 2015 年 7 月公开发布以来，Chameleon 已吸引了超过 4,000 名用户参与 600 多个教育和研究项目。在第三阶段，Chameleon 将通过添加新硬件和新功能来极大扩展其核心功能。支持的实验范围将扩大到包括物联网 (IoT) 和边缘计算、更广泛的网络实验以及分类硬件实验。该系统还将通过提供工具来扩展对可重复性的支持，这些工具允许研究人员打包他们的实验以进行重复，并使其可以轻松地发布、发现和引用它们。最后，第三阶段将继续打包 CHI-in-a-Box 基础设施，即 CHI-in-a-Box，允许其他人部署和管理类似于 Chameleon 的测试平台。 Chameleon 项目将继续其为云计算领域的计算机科学研究和教育提供平台的使命，云计算是未来计算专业人员的关键技能。与传统的实验平台不同，Chameleon建立在主流开源云技术（OpenStack）之上；这不仅意味着其用户和运营商只需通过测试床即可熟悉主流云功能，而且 Chameleon 项目的开源贡献直接影响云行业广泛使用的系统。最后，通过对实验管理和可重复性的支持，Chameleon 影响了 CS 实验方法，并使更高效的研究成为可能。要使用 Chameleon 或了解有关该系统的更多信息，请访问 www.chameleoncloud.org。对于任何对系统开发或 Chameleon 打包（即 CHI-in-a-Box）感兴趣的人，请访问 github 存储库：https://github.com/ChameleonCloud/chi-in-a-box/wiki。如果用户想探索 Chameleon 迄今为止的踪迹，请参阅 https://www.scienceclouds.org/cloud-traces/。这些网站将在整个项目期间得到维护。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
