We've got some great updates about new hardware, some provided by an entirely new Chameleon site at the National Center for Atmospheric Research. Welcome CHI@NCAR, as well as new AMD nodes (some w/ GPU) at CHI@TACC, and more SSDs and GPU capacity at CHI@UC.

Learn about IndySCC, a virtual version of SuperComputing's Student Cluster Competition (SCC) which was conducted on Chameleon! Learn all about the competition, how it was run with Chameleon, and of course, the winners!

Check out Chameleon Daypass! Enable Daypass for your Chameleon experiment, and let any user, including those without a Chameleon allocation, try running your experiment! You can even include a QR code which links to your experiment in your paper or on a poster. Learn about the latest innovation in reproducibility and how to make it work for you in this blog. 

In this month's changelog, we announce an early preview of a Public API for Trovi, Chameleon's system for reproducibility, which has wider amibitions for the coming year. Additionally, we review more additions to the hardware catalogue at CHI@UC and a new release of CHI-in-a-Box!

Interested in using Chameleon for edge computing? We've released our report on the very first CHI@Edge community workshop that happened in September! Learn about some of our early users' research and our top takeaways from the first few months of operating an edge testbed. 

Learn all about extending Pegasus, a fully featured workflow management system, to edge devices in one of the first examples of research done on CHI@Edge, Chameleon's edge computing testbed.

The Chameleon Tickets of the Year blog returns for a second time! To close out the year, we’ve gathered and answered some of the most commonly seen user problems brought to the Help Desk’s attention in 2021. As always, creating a helpdesk ticket is the fastest way to reach the Chameleon support team and get help, though it doesn’t hurt to check our documentation and the Chameleon FAQ as well!

It's our post-SC wrapup! In this month's changelog, we've got several new edge devices to announce, as well as improvements for UEFI boot support, a better way to view and track your allocation spending, and more.

Increasingly more computer science systems conferences are using Chameleon for artifact evaluation. Learn more about how to use Chameleon for reproducibility; including tips both for organizers of these events and artifact authors. 

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.
