This month, we bring to you the much awaited filesystem preview, and a massive Openstack upgrade. We also have a new CHI-in-a-Box version to go along with the upgrade, and some reservation usability improvements.

Chameleon was recently awarded the Best Paper Award at PEARC '22.

Did you ever wonder what makes your favorite testbed “go”? The answer is  CHameleon Infrastructure, or CHI for short – packaged as CHI-in-a-Box so that anybody can run their own testbed. We blogged about it a year or so ago, and a lot can change in a year, so this blog brings you some important updates. Not least, there is now a paper on CHI-in-a-Box so you can join the testbed as an Associate Site!

Graph Pattern Mining (GPMI) applications are considered a new class of data-intensive applications -- they generate massive irregular computation workloads and pose memory access challenges, which degrade the performance and scalability significantly. Researchers at the Illinois Institute of Technology approach the problem by using the emerging process-in-memory architecture. 

This month, we’re excited to announce some great usability improvements to Chameleon, new features on CHI@Edge, and some fixes for CHI-in-a-Box. We also have some great papers in PEARC! Don’t forget about the Summer with Chameleon webinar series too!

Learn more about Trovi, Chameleon's experiment repository, and how you can use it to collaborate on experiments and share your work. The blog also covers Trovi's integrations with Zenodo and GitHub, creating a more seamless process for running your experiment - from production to publication. 

Interested in protecting remote devices from malicious actors? Learn about how a researcher at the University of Missouri is approaching this problem with genetic algorithms and host fingerprinting! Also included is a YouTube video where Dr. Aksoy discusses this research.  

Using Chameleon for student interns, REUs or summer courses? Sign up for a series of webinars that introduce the platform, including CHI@Edge, the edge computing platform, on June 8th and 9th. 

Lots of fabulous news this month! We have some big CHI@Edge updates and final CHI@Edge version 2.0 release, including a new artifact to make setting up experiments easy. We also greatly improved the implementation of Trovi, including the ability to import and export artifacts from/to git.

Learn all about CHI@Edge, Chameleon's edge computing testbed, how to interact with CHI@Edge devices, research projects that came out of our early preview and how to enroll your own device on CHI@Edge! Check out the post for links to an interactive user guide on Trovi, a YouTube video, and how to join the CHI@Edge Google Group to stay up to date with the latest news!
