A configurable experimental environment for large-scale edge to cloud research

The Sixth Chameleon User Meeting will be held April 15-16, 2026 at the NCAR Mesa Lab in Boulder, Colorado. This year's meeting's theme focuses on computer science research and education in Artificial Intelligence (AI) and Machine Learning (ML). The objective of the meeting is to create a community discussion on AI research, approaches to education, and most importantly what platform you need – or may need in the future – to solve the hard problems and train the workforce of the future. We invite researchers and educators using Chameleon to submit presentation proposals sharing their experiences. Come to network with scientists working on similar topics, share tips on how to muster resources and data for hard-to-get experiments, and find materials and digital artifacts to teach AI classes!

As in previous years, we will reimburse travel expenses of up to $1,500 for the presenting authors of the top 10 selected abstracts (one author per abstract).

Prof. Fraida Fund's (NYU) recent webinar presented her extensive open source materials that she developed and used to teach a large (190+ students) graduate-level course on machine learning operations (MLOps) -- not just how to develop an ML model and code in isolation, but also how to design and implement a full-fledged system to develop and deploy ML models in various environments. The webinar was a great success: we had 100+ registrations, close to 50 participants at the webinar, and extensive Q&A following the presentation. We are excited to announce that the recording of her presentation, along with materials and slides, are available on the FOUNT website.

Watch the presentation and view the materials she shared from her webinar. Let Marc Richardson (mtrichardson@uchicago.edu) know if you'd be interested in hosting similar webinars like hers in the future.

This month brings exciting updates including enhanced hardware browser integration, CHI@Edge stability improvements, and expanded support for distributed training on AMD GPUs, along with announcements about upcoming webinars and our sixth user meeting at NCAR’s campus in Boulder.

Trovi helps you package and share computational artifacts that run on Chameleon, from Jupyter notebooks to complete experimental workflows. Whether you're importing code from GitHub, organizing artifacts into Collections, collaborating with co-authors, or publishing work to get a citable DOI, these tips will help you make the most of Trovi for your research and teaching.

The Chameleon User Meeting is an in-person forum held over two days for users to discuss their research and education projects, share experiences of working with the Chameleon testbed, solve challenges together, and propose new features that will make their experiments and education projects easier. The User Meeting will have features to interest Chameleon newbies as well as veterans, end-users and operators, and researchers and educators. For our sixth meeting, we are grateful to co-host with the National Center for Atmospheric Research (NCAR) at its main campus in Boulder, CO.
