Warm welcome back! We hope that your summer was fabulous in every possible way and now that finally both the semester and the quarter have started you are ready to embark on new adventures. We are here for this with tips for Chameleon newbies and an update for our wizened veterans.

We're recruiting another round of Reproducibility Ambassadors. PhD students who package experiments on Chameleon and Trovi can receive up to $1,000 in travel assistance to attend a conference of their choosing and organize a small event on reproducibility there. Applications are accepted on a rolling basis and funds are limited.

Great news from Chameleon! Our new site at NCAR just got even better with the addition of 5 NVIDIA Grace A02 nodes (to the 40 Zen 5 nodes), Trovi got better now linking artifacts with relevant papers and videos, and resource discovery got better with the addition of VM flavors.

ACM SIGHPC is accepting applications for the Ewing "Rusty" Lusk Travel Scholarship for SC26. It provides full conference registration plus up to $1,600 in travel reimbursement to help graduate students without institutional funding attend the conference. Applications are due 30 September, 11:59 PM AoE.

We're looking for two undergraduate researchers to join the Chameleon team this fall, funded by NSF's Research Experiences for Undergraduates program. One position works on Trovi and artifact reproducibility, the other on automated verification of testbed hardware. Roughly 10 hours a week, and remote applicants are welcome.

Fantastic news on Chameleon: our users are back in force – welcome to the new academic year! In the August newsletter we are looking for REU students, looking forward to meeting at least some of you at multiple upcoming research events, and looking after your needs in the changelog announcements. In particular, one interface for bare metal and VMs has finally landed – as have OpenStack upgrades!

Join the Chameleon team in person at PACT 2026 in Chicago on October 19th for a hands-on tutorial covering the full experimental lifecycle on Chameleon—from resource discovery and hardware allocation to packaging reproducible artifacts on Trovi.

Join the REPETO project's BoF session at VLDB '26 on September 3 to learn how to package and reproduce database research experiments on Chameleon and Trovi.

Whether you're choosing a GPU, a memory-heavy node, or a cluster of homogeneous machines, Chameleon Resource Discovery helps you plan both the hardware and the timing—across bare metal, VMs, and every site.

Great news on Chameleon! I hope everybody is enjoying the vacation – in the meantime, in the July edition of Chameleon newsletter we are looking for REU students, looking at 10 years of Chameleon in a paper just presented at PEARC'26, and hope to see you at the MERIF workshop – read on, if you would like to represent Chameleon as a user. Our changelog has important announcements of upcoming changes in how bare metal versus VM instances are managed, news of base Chameleon Infrastructure (CHI) upgrades, and resource discovery for VM flavors.
