An experimental platform for edge to cloud research

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).

Registration is now open for the 6th Chameleon User Meeting (April 15-16, 2026) at NCAR Mesa Lab in Boulder, CO!

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.
