Chameleon Changelog for February 2021

Winter's almost over! This month we have a lot of announcements, notably a big facelift for CHI-in-the-Box, the packaging of Chameleon, but also a new interactive handbook for Chameleon and some nice KVM capabilities.

Using AI to Direct Traffic: Building Self Learning Networks on Chameleon

Dr. Mariam Kiran is a research scientist in the Scientific Networking Division, as a member of the Prototypes and Testbed group at ESnet, LBNL, and is leading research efforts in AI solutions for operational network research and engineering problems. In this blog, she discusses her research project DAPHNE (Deep and Autonomous High-speed Networks), her use of Chameleon, and her research background.

Setting Up an Associate Site: An Interview With Northwestern University

Sit down with Fei Yeh, an associate researcher with the International Center for Advanced Internet Research (iCAIR) at Northwestern University, to learn how a Chameleon associate site was set up, how you can use it, and his experience.

Chameleon Changelog for January 2021

Hey! It's your friendly neighborhood Chameleon changelog, back from a long vacation. This month we announce general availability for CHI@NU, new Cascade Lake racks at CHI@TACC, and more!

Interactive and Repeatable Experiments on Chameleon with Jupyter Notebook

As another semester begins, we’ve rounded up a series of fully packaged experiments on Chameleon. These experiments are all publicly available on Trovi, Chameleon’s sharing platform. The experiments can be used for classes to introduce different topics, tools, or datasets, or serve as an introduction to provisioning resources on Chameleon with Jupyter Notebook. Once you launch an experiment, you can edit the notebook, allowing individual experimentation, and letting you introduce variation, such as trying different resources or datasets.

Biometric Research in The Cloud

January’s User Experiment’s blog features Keivan Bahmani, a PhD candidate at Clarkson University. Learn more about Bahmani and his use of Chameleon for biometric research.

2020 End-of-year Changelog

We'd like to take a brief moment to reflect with gratitude on what went right this year, at least in the (small) realm of our work on this research testbed. So here’s one year in review, representing combined “changelog” information from the entire year.

Tickets of the Year: Solutions to Your 2020 (Ticket) Problems

Is your instance not launching? Are your Floating IPs drifting aimlessly through the ether? Do you have a PI eligibility request?
