In 2021, we introduced CHI@Edge, a cutting-edge testbed tailored to the dynamic needs of edge computing and IoT research. Our initial offerings included a robust selection of devices like Raspberry Pi 4s, Nvidia Jetson Nanos, and Jetson Xaviers, tailored for high-performance yet low-power edge computing tasks. Today, we're thrilled to announce the transition of CHI@Edge from a widely embraced preview to its official full production phase.

As the digital age accelerates, the importance of reproducibility in computational science has never been more critical. This year, in a unique convergence with the SC24 conference, we are thrilled to announce a workshop focusing on the theme of "Practical Reproducibility" in Computer Science. Scheduled for November 18, 2024, at Terminus 330 in Atlanta, this full-day workshop promises to be a milestone event in advancing the science of reproducibility.

This month, we are very excited to announce CHI@Edge is coming out of preview! We also have new artifacts that allow you to explore Fabnet with, and new per-user SU budgeting.

In the era of exponential data growth, the "Baleen" project introduces a groundbreaking approach to flash caching, utilizing machine learning to optimize data storage. This method intelligently decides what to store and prefetch, significantly reducing the hardware required, lowering costs, and enhancing sustainability. This blog explores the challenges of managing vast data volumes and how "Baleen" offers a novel solution, poised to revolutionize data center operations and sustainability practices.

Discover how Chameleon's testbed capabilities have been enhanced with the introduction of the FABRIC Layer 3 connection in our new blog post. Learn about the powerful and flexible networking options it offers, how it simplifies the process of routing to FABRIC resources, and how it enables low-latency and high-bandwidth traffic routing between CHI@UC and CHI@TACC.

This month, we have a packed changelog, we have a lot of exciting updates with FABRIC connectivity, and we’ve added a second interface to nodes on CHI@UC that did not have one. Additionally, for Edge users, we have improvements to interacting with containers and using Jetson Nano GPUs. Lastly, there are updates to our lease stacking policies.

File systems are a fundamental part of computer systems, which organize and protect the files and data on assorted devices, including computers, smartphones, and enterprise servers. Due to its crucial role, vulnerabilities and bugs in the file system can lead to severe consequences such as data loss and system crashes. After decades of development, file systems have become increasingly complex, yet bugs continue to emerge. Meanwhile, many new file systems are invented to support new hardware or features, often without undergoing comprehensive testing. To address these gaps, we develop a checking framework (Metis) that can thoroughly and efficiently test file …

The BigDataX program is a Research Experiences for Undergraduates (REU) site in Chicago, Illinois.
