Researchers at the University of Missouri explore novel middle-man data poisoning attacks with facial authentication applications and propose a defense architecture. Learn more about these attacks, their solution, and the researchers themselves in November's featured user experiments blog.

This year Chameleon hosted the IndySCC competition, analogous to the in-person Student Cluster Competition (SCC) of Supercomputing. Teams use cloud/shared resources to optimize a variety of HPC workloads in order to complete the most computations during a 48 hour final, all while staying below a strict power cap. Learn more about the compettion, Chameleon's support, and where you can see the results.

In this month's changelog, we're excited to announce a new batch of hardware at CHI@UC, including more flexible network topologies, some very high-powered nodes, and InfiniBand-connected GPUs. We've also added support for provisioning ARM-based machines to support CHI-in-a-Box associate sites who wish to configure ARM nodes. As always, more inside!

The recently released Chameleon Phase 3 hardware will support new experiments in networking, disaggregated hardware, and more. Learn more about the different types of hardware and what kind of experiments they're best suited for!

Learn about University of Chicago PhD student Chengcheng Wan's research on designing a solution to integrate machine learning components into traditional software systems to maximize energy efficiency, latency, and accuracy constraints at machine learning, system and application levels, with related research published at USENIX ATC, ICML, and ICSE.

In this month's changelog, we announce a few really cool new features, one of which has been on our most-requested list for a long while: PI delegate! Besides that, there is a brand-new preview capability that allows you to share your Trovi experiments with non-Chameleon users so they can reproduce your work w/o an allocation. More details, as always, inside.

Join us on Friday, October 22 at 1.30p CT for Chameleon Live - an informal webinar where the Chameleon team will showcase the newest features of the testbed and answer questions from the community. Think of it as office hours to learn all about Chameleon updates and how to use them! Register and submit questions here: https://forms.gle/4itPs913vFTbnnGG9

New to Chameleon? Or are you a Chameleon veteran interested in exploring a new feature or tool you’ve seen on Chameleon, but not sure where to begin? Look no further - we’ve gathered the top Chameleon tutorials for you to use as inspiration! Ranging from full-length webinars to short overview videos, you can learn and explore new ways to experiment on Chameleon!

See Chameleon Lead PI Kate Keahey's keynote at IC2E on Experimenting from Edge to Cloud on October 6th! Learn more about the talk and register here: https://bit.ly/3APDL65
