This month we're highlighting the last chance to register for the Sixth Chameleon User Meeting, a new webinar recording from UTEP's MINCER team, platform updates including multi-instance GPU support, new cloud traces, switch performance improvements, and several testbed usability enhancements.

Data centers waste enormous performance potential because software evolves faster than profiles can be collected. Wax, developed by Tawhid Bhuiyan and colleagues at Columbia University, uses source code and debug information to recover 65–93% of fresh-profile performance gains from stale profiles—outperforming the state of the art by up to 7.86 percentage points across five real-world data center applications.

Chameleon's stitch port feature lets you connect bare-metal GPU servers directly to FABRIC's network fabric — no public IP required. This post walks through a Trovi artifact that provisions a Chameleon GPU node, links it to a FABRIC slice over fabnet, and runs LLM inference across the stitched network. Grab the notebook and adapt it to your own cross-testbed workflows.

This April, we're bringing together researchers, educators, and infrastructure builders for two days of honest conversation about AI on research computing infrastructure. We're thrilled to kick things off with a keynote from one of HPC's leading voices.

This month we're highlighting an exciting keynote announcement for our upcoming User Meeting, reproducibility work at FAST 2026, a new webinar recording, and several platform updates including improvements to Trovi, cc-snapshot, CHI@Edge, and python-chi.

Teaching cloud computing without tying students to a single vendor is harder than it sounds. Dr. Michael MacLeod at Austin Community College found a solution in Chameleon, and the results speak for themselves: 14 courses, 420 students, and a curriculum that's still growing. Read more in the blog.

Two PhD students selected through the Reproducibility Ambassador program funded by the NSF REPETO project are heading to FAST '26 to share how researchers can package and reproduce their experiments using Chameleon Trovi. Join them on February 24th and 25th to see it in action.

Since KVM@TACC now requires bounded reservations, VM instances and their data are deleted when reservations end. While snapshots can preserve entire instances, persistent volumes offer a more flexible solution for storing experiment scripts and data that persists independently of your VM lifecycle. This guide walks through creating volumes via the GUI, partitioning and mounting storage, and extending volumes as your storage needs grow.

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).
