Season's Greetings from the Chameleon Team!

As the year draws to a close we want to thank you for another fabulous year of innovative ideas and exciting resaerch. May your holidays be magical and joyful, and the New Year full of exciting adventures! 

As in the years before, the Chameleon Help Desk will be on snooze (make sure to get your tickets in by the 20th!) but we will make up for it by continuing our Chameleon for Christmas "double lease" tradition -- between 19th and 22nd (inclusive) you can make 14 day leases -- and this does include GPUs! …

This month we have presentations from the 5th Chameleon User Meeting on practical reproducibility, and lots of housekeeping on Chameleon. These include improvements to IP availability, and fixes to the core testbed, Trovi, and CHI@Edge.

Learn how researcher Redwan Khan uses Chameleon to develop FedCaSe, an innovative framework that tackles the challenges of distributed machine learning across diverse edge devices. This groundbreaking research demonstrates up to 29x improvement in client participation and 81x better data access efficiency, paving the way for more accessible and efficient AI systems.

Running distributed applications across multiple nodes is a common need in scientific computing, but setting up MPI clusters can be challenging, especially in cloud environments. In this post, we'll explore a template for creating MPI clusters on Chameleon that handles the key configuration steps automatically, letting you focus on your research rather than infrastructure setup.
