A Jupyter notebook has been added to your Chameleon Jupyter Hub environment to show how to automate deploying a server and several clients which are configured with the names and IPs for every single other host in a custom isolated network. Also included are examples of several tricks you might find useful for deploying a complex experiment.

From everyone at Chameleon, we hope you had a pleasant holiday and welcome to the new year! Details inside about new HTTPS capabilities and important webinar/conference dates to kick things off in 2020.

The history command available in Bash is a useful tool, and you probably use it frequently in your daily routine jobs to check the history of the commands executed by the user. In this blog, we will see how an equivalent tool in Chameleon can help you check the experiment setup events you performed on Chameleon. 

This month we announce a new rack of Cascade Lake nodes for your enjoyment at CHI@TACC!

Modern computational science depends on many complex, compute, and data-intensive applications operating on distributed datasets that originate from a variety of scientific instruments and data repositories. Two major challenges for these applications are: (1) the provisioning of compute resources and (2) the integration of data into the scientists’ workflow.

There is a poem about the 5th of November, but sadly I couldn't find a way to adapt it for this changelog. Anyways, learn about our new KVM cloud! And we also packed in a few other goodies this month.

Jupyter notebooks are a great tool for structuring your computer science experiments on Chameleon because they allow you to iterate on your idea interactively, intuitively, and quickly. But, it may not be obvious how you can leverage this tool for running an experiment...

One challenge for power budgeting systems is how to power cap dependent applications for high performance. Existing approaches, however, have major limitations. Our work proposes a hierarchical, distributed, dynamic power management system for dependent applications.

Welcome to October, and a new (academic) year for all of you! Over the summer we’ve been working on some cool new things and are now happy to release them into the world for your use and enjoyment. In particular, say hello to the new Sharing Portal.

This post from Chameleon user, Massimo Canonico, outlines educational slide decks that will be particularly helpful for those who wish to incorporate Chameleon into their curriculum.
