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. Students work with mentors on research projects covering a wide variety of computer science subject areas, including Data Management in Scientific Computing and Blockchains, Data Analytics and Systems, Operating Systems & Computer Architecture, Edge Computing with CHI@Edge, and much more. Apply now! Application deadline is March 4, 2024

This month, we bring a lot of updates to our CC-images. And we also remind users about our user survey and upcoming maintenance at CHI@UC.
 

The REPETO project (an initiative funded by the NSF FAIROS RCN to build a network for practical reproducibility in experimental computer science) invites FAST’24 attendees to join our BoF sessions planned for February 27th and February 28th to learn about packaging storage research experiments on Chameleon. Pre-register with us for the BoF sessions by February 20, 2024 (link to interest form is in the blog!).

We invite all users to submit feedback through the survey. The responses we receive will directly impact future development of Chameleon, including where to focus hardware procurement efforts and extension of testbed capabilities. The survey is a great opportunity to help guide the future of Chameleon! We will accept responses until Feb. 6, 2024.
