We're excited to announce that Valerie Taylor, Director of the Mathematics and Computer Science Division and Distinguished Fellow at Argonne National Laboratory, will deliver the keynote address at the Sixth Chameleon User Meeting, taking place April 15–16, 2026 at NCAR's Mesa Lab in Boulder, Colorado.

Dr. Taylor's talk, Utilizing LLMs for Refactoring of Parallel Scientific Codes for Energy Efficiency, will present LASSI-EE — an automated LLM-based framework that generates energy-efficient parallel code through runtime power profiling, energy-aware prompting, and self-correcting feedback. Results include benchmarks run on NVIDIA A100 and AMD MI100 GPUs available on Chameleon Cloud, with energy efficiency improvements of nearly 3x over standard LLM prompting.

Dr. Taylor is an IEEE Fellow, ACM Fellow, and AAAS Fellow, and also serves as CEO and President of CMD-IT. Her work sits at the intersection of high-performance computing and applied AI — a natural fit for this year's meeting theme.

Join us in Boulder. View the full program and session details on the event website, and register via Eventbrite.

And if you're arriving early, join us for a Pre-Meeting Hike on April 14th at 4:30 PM — a chance to explore the Boulder foothills and connect with fellow attendees before the meeting kicks off.
