This month, we have new H100 GPU nodes on KVM@TACC! Today, you can launch VM instances with 1 full H100 GPU. This hardware comes with a brand new workflow for reserving VMs. It’s important to note that this reservation workflow will be rolled out to the rest of KVM later in the summer. Additionally, we have refreshed our documentation. Lastly, CHI-in-a-box comes with a new image deploy tool for associate sites.
 

This month, we have new OS images with AMD ROCm and Ubuntu 24 on ARM. Additionally, we have improvements to mounting object store buckets using rclone, a new message-of-the-day, and we’ve fixed the firewall confusion on KVM@TACC.
 

Learn how to leverage Trovi's new GitHub integration to easily create and update reproducible research artifacts. This step-by-step guide shows you how to configure your GitHub repository with RO-crate metadata and import it directly into Trovi, enabling better collaboration and adherence to FAIR principles for your experiments.

This month, we have reminders for KVM@TACC and CHI@Edge outages later this month. Additionally, we have version 1.1 of python-chi, and improvements to reservations!
 

This month, we are excited to announce new updates to the Trovi dashboard, and the launch of the Chameleon User Forums. Additionally, please note our new data policies, as these will take effect soon!

Happy New Year! We’ve had a busy 2024 with new hardware and many system improvements! In our changelog today we note a couple of nits that slid under the wire in the last year and propose important changes to our virtualized offering – please, read carefully we are asking for your feedback to make sure that those innovations don’t interfere with your ability to use the system for your experiments.
