Today we share a very unique user experience -- a conversation with Rafael Tolosana Calasanz who is an Associate Professor in the Department of Informatics of the University of Zaragoza, Spain and has participated in the reproducibility initiative at SC. Rafael shares with us his experiences reproducing artifacts on Chameleon and his insights on reproducibility and its importance to the modern scientific process. 

Chameleon will organize two BOFs on the topic of reproducibily at the USENIX FAST'23 conference.

The BOFs will be held on Tuesday and Wednesday 02/21-22 to discuss how to best package storage experiments on Chameleon for reproducibility. We will present several experiments patterns that should help you package your own experiments as well as actual packaged experiments for reproducing. Chameleon staff will be around to answer questions and provide technical help in packaging and reproducing experiments. 

The date for the Chameleon User Meeting in Chicago has been set to May 2-3. We will be back very soon with a full announcement and call for presentations but in the meantime please block the time in your calendar because we are all looking forward to seeing you here! 

Great news in Chameleon-land! We’re kicking off the new year with upgrades and fixes to JupyterHub, and usability improvements to the web dashboard Horizon – and save the date for the first post-pandemic in-person Chameleon User Meeting! 
 

We go over the benefits of using a bastion host to administer your cluster. It's the easiest way to deploy a secure cluster of hosts for your experiments, and it also helps to save resources!

This month's user experiment blog covers some interesting work on tensor analysis from researchers at Arizona State University.

This has been a fantastic year for Chameleon and we go over all the major features the project acquired. We also have a couple of new tidbits: the long awaited CHI@Edge Xena upgrade which will be interesting to our edge users and an announcement of the Chameleon JupyterHub infrastructure upgrade coming up first thing in the New Year. Have a fantastic Holiday and Happy New Year!
 

This month, we talk to Rick Anderson from Rutgers University about his experience using Chameleon to experiment with autonomous vehicles!

To help make your spirits bright we will continue our “Chameleon for Christmas” tradition with end of the year 14 day leases – you get twice as much time for being twice as nice! This feature will be available for a limited time only. Also, a reminder that HelpDesk will be closed during the Holidays – please, read the post for all the details and plan accordingly. Happy Holidays!

As has become holiday tradition, we review some of our most common tickets of 2022, and provide answers and context that we hope is a helpful gift for all of our experimenters in the coming year.
