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

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.

SC2025 is taking place in St. Louis, Missouri from November 16 to 21, 2025. Kate Keahey, Chameleon PI, will be attending the conference and hopes to see some of you there. In this blog, we list some of the events where Chameleon is getting let out of the box!

Reproducibility is a cornerstone of scientific computing, yet achieving consistent results across different hardware environments remains a significant challenge in HPC research. The MINCER project tackles this problem head-on by providing researchers with an automated performance measurement appliance on Chameleon Cloud. Using Docker containers and the PAPI framework, MINCER enables standardized collection of performance metrics across CPUs, NVIDIA GPUs, and AMD GPUs, making it easier to compare results and understand how system-level factors influence computational performance. This post explores how MINCER is helping make HPC experiments more reproducible and accessible to the research community.
