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 systems and is easy to apply to a wide range of file systems. Metis helps developers and users identify file system bugs and offers directions for reproducing and fixing them.

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.

Happy New Year! We are back and happy to see you are back as well! In this changelog edition we highlight the most significant testbed changes and upgrades from the last year and hint at some surprises yet to come. Looking forward to working with you in 2024!

Get the inside scoop on Chameleon Cloud’s common user issues and smart fixes in our latest 'Tips and Tricks' blog, highlighting a year of learning and problem-solving.

In this end-of-year blog, the Chameleon Team expresses gratitude for the community's support and achievements in 2023. Highlighting the innovative work showcased in user experiment blogs, the team invites more exploration. The blog also announces the holiday schedule for the Chameleon Help Desk and the exciting return of the "Chameleon for Christmas" double lease offer, allowing extended access to resources, including GPU nodes. The post concludes with warm holiday wishes and anticipation for continued collaboration in 2024.

Great news for the Chameleon Cloud Community! The IndySCC site, previously exclusive to IndySCC teams, is now accessible to all users until January 5th, thanks to the University of Colorado Boulder's support. With 164 nodes featuring powerful hardware, including 2x 12 core Haswell CPUs and 100G Intel Omni-Path, it's a fantastic chance to expand your research capabilities. Remember, new reservations won't be accepted after January 5th, so make the most of this opportunity while it lasts.
