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. 

A new dedicated Jupyter appliance, new ways to get your code into the Jupyter environment, upcoming webinars, and more inside!

Did you ever want to create a lease for a specific node? Did you ever want to create a lease that does NOT include a specific node? Ignore a node that has been reserved? Reserve a whole rack perhaps? Or just a few nodes but on the same rack? Then look no farther; here are five tips and tricks for node selection and node avoidance!

CHI-in-a-Box beta release, a new MPICH appliance, CUDA10 support for Ubuntu, and more inside! See what we've been cooking up this summer.

This month: a new firewall security feature for bare metal nodes, updates to official disk images, and a webinar you should take a look at if you want to learn more about wide-area layer-2 network provisioning with Chameleon!
