An experimental platform for edge to cloud research

Recent news

  • Chameleon Newsletter & Changelog - January 2026

    Testbed updates, new features, webinars, and other exciting news from our user community
    by Marc Richardson

    2026 is in full swing now. The Chameleon team in Chicago is struggling to keep warm, but the cold isn’t slowing down our momentum as we enter a new year. This newsletter brings upcoming changes to Trovi and the appliance catalog, with announcements about open registration for the 6th Chameleon User Meeting (Boulder, CO, April 15-16), a reminder to submit to the call for presentations, and upcoming webinars (next up: How to Use CHI@Edge to Enable Edge to Cloud Experimentation on Feb. 17th).

  • Core Hours and Carbon Credits: Incentivizing Sustainability in HPC

    Researchers demonstrate that linking resource costs to energy consumption can reduce HPC energy use by 40%
    by Alok Kamatar

    A survey of 300+ HPC users reveals that fewer than 30% are aware of their energy consumption. This research introduces Energy-Based and Carbon-Based Accounting models that tie computing costs to environmental impact, demonstrating through real experiments and simulations that such incentives can dramatically reduce energy use while maintaining scientific productivity.

  • Streamlining Resource Discovery and Reservations

    Learn about our recent upgrades to resource discovery and reservations on Chameleon
    by Paul Marshall

    We’re excited to shine a spotlight on the recently refreshed hardware discovery browser on Chameleon! Launched a little while ago, this upgrade makes it easier and faster to pinpoint the exact hardware you need for your experiments, connecting you directly to real-time scheduling and reservations.

    As you most likely know, Chameleon offers dedicated, reservable resources. That means your work gets exclusive access to the nodes you choose but navigating hardware specs and reservation calendars together can sometimes be a bit of frustration.

    The new resource discovery experience helps you link “what hardware am I getting?” with “when can I actually run?” into a more streamlined workflow than previously.

  • Call for Presentations: Chameleon User Meeting 2026

    Submit your proposals to present in Boulder, CO at NCAR's Mesa Lab!

    The Sixth Chameleon User Meeting will be held April 15-16, 2026 at the NCAR Mesa Lab in Boulder, Colorado. This year's meeting 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).
