This month we're introducing a dedicated Resource Updates section to our newsletter, announcing Ponte Vecchio GPUs at CHI@TACC for a limited time, improving CLI authentication with the new ccauth tool, increasing the image size limit to 100GB, adding Ubuntu 26.04 support with a new fractional GPU image, and improving CHI@Edge BYOD enrollment. In the community, Kate Keahey delivered a keynote at CCGrid 2026 in Sydney.

Distributed storage systems are upgraded constantly, and one subtle class of bug — data format incompatibility, where a new version misreads data written by the old one — ranks among the leading causes of cloud incidents during upgrades, with consequences as severe as data loss and cluster-wide outages. UpFuzz, an award-winning open-source fuzzer from Purdue University, is the first tool built specifically to hunt these cross-version bugs. It has already uncovered 15 previously unknown failures in the latest stable releases of Cassandra, HBase, and HDFS — and its evaluation was run on bare metal testbed infrastructure that included Chameleon.

Trovi is expanding beyond user-uploaded artifacts to include selected reproducibility artifacts from major computer science conferences like EuroSys, SOSP, and SC. We’ve built a pipeline to crawl, index, and surface these external artifacts in the same interface you already use, and connected them to Chameleon so you can go from discovering an interesting artifact to running it on bare metal in minutes.

The RAPTOR team from Argonne National Laboratory and collaborating institutions wins the SC25 Best Reproducibility Advancement Award, using Chameleon Cloud to make their artifact fully reproducible. This marks the second consecutive year a Chameleon user has taken home this honor.
