Online Now – Fraida Fund (NYU) presents her large-scale MLOps Class on Chameleon

Check out the full presentations, paper, and slides from Fund

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 …

From GitHub to Publication: Using Trovi Effectively

How to organize, share, and publish your Chameleon experiments

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.

Save the Date! Sixth Chameleon User Meeting - April 15-16, 2026 - Boulder, CO

Mark your calendars for our upcoming User Meeting co-hosted with NCAR; watch for updates!

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.

Introducing MINCER’s Performance Measurement and Reproducibility Appliance

Building a Standardized Framework for Reproducible Performance Measurements Across Diverse HPC Architectures

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.

Bare Metal or KVM? Which Should You Choose and When

A detailed comparison of hardware access, reservation systems, and storage options for users

Not sure whether to use bare metal or KVM for your next Chameleon experiment? You're not alone. With KVM's recent addition of H100 GPUs and advance reservations, the choice isn't always obvious. This comprehensive comparison walks you through the practical trade-offs: when you need the isolation of bare metal for accurate benchmarking, when KVM's 6-month leases and resource sharing make more sense, and how to navigate the different storage and networking options. Make informed infrastructure decisions that accelerate your research.

Chameleon Changelog for September 2025

This month we have some exciting updates to Trovi’s dashboard, support for 4xGPU instances on KVM@TACC, improvements to cc-snapshot, and a new webinar series!

Student Spotlight: Three Chameleon Projects Heading to SC'25

Bioacoustics, Snapshots, and AI: Student Innovations Pushing the Boundary of Science

This summer, three talented students used Chameleon to tackle challenges ranging from wildlife conservation to reproducibility and AI-assisted documentation. Their innovative work earned them spots at the ACM Student Research Competition at SC'25, where they'll present posters on autonomous bioacoustic monitoring, snapshot performance optimization, and intelligent documentation systems. Discover how Hudson Reynolds, Alex Tuecke, Zahra Temori, and Saieda Ali Zada leveraged Chameleon's infrastructure to create impactful solutions.
