Don't let authentication problems derail your research momentum. This practical guide demystifies Chameleon's login system and arms you with clear, step-by-step solutions for the authentication challenges that frustrate users most. Learn to confidently navigate multiple accounts, identity provider changes, and stubborn login issues.

New H100 hardware on KVM@TACC, and good news about KVM lease limits, quotas, and SU cost. Additionally, we have SU changes for baremetal, an improved the resource browser, and are announcing the deprecation of TACC login.

Traditional distributed databases are often slowed down by network communication overhead. The Tigon project introduces a new database design that tackles this bottleneck using Compute Express Link (CXL), a technology that allows multiple computer hosts to access a shared memory pool. Tigon employs a hybrid approach, keeping most data in fast, local host memory while moving only actively shared data to the CXL memory. This results in significant performance gains, achieving up to 2.5 times higher throughput than traditional databases. Since the multi-host CXL hardware required for this research was not yet commercially available, the project was brought to life …

Have you completed the Chameleon Getting Started guide and are wondering what comes next? This post will help you dive deeper by moving beyond the basics. You will learn how to interact with the Chameleon API from the command line on an instance and from your laptop. We'll also cover how to use tools like rclone and cc-snapshot to securely save and manage your valuable research data.

This month, we have a significant change to KVM@TACC: as per our announcement last month, all KVM instance launches will now require an advance reservation step in the allocation workflow (with the “advance” potentially being once second from now, i.e., on demand). Also, we have cool new hardware on CHI@Edge, and improvements to the “message of the day” on Chameleon-supported base images

Cloud infrastructures are powerful but often operate as isolated islands. See how Germán Moltó and his team are bridging these gaps, enabling massive, collaborative scientific experiments by connecting clouds across the Atlantic using the Infrastructure Manager to dynamically deploy custom testbeds.

Whether you're provisioning your first bare metal node or building complex edge computing experiments, finding the right documentation quickly can make the difference between a productive research day and hours of frustration. Chameleon's documentation ecosystem has grown to include multiple specialized resources—each designed for different needs. This guide will help you navigate to the right place, the first time.

This month we have changes to KVM@TACC that allow you to launch any VM flavor from a reservation, which soon will be required. In a few months, we’ll shut down VMs that aren’t from a lease, so make sure to check out the details! We’ve extended python-chi with better support for KVM, adding methods for flavor reservation, managing security groups, and volumes.

IT infrastructure forms the backbone of modern society, but traditional scaling approaches face critical limitations that expose services to security and reliability shortcomings. This research investigates Statistical Multiplexed Computing (SMC) principles to build infrastructures without scaling limits, similar to how TCP/IP protocols enabled indefinite network scaling.

NVIDIA H100 GPUs are now available on KVM@TACC through a new reservation-based system. Learn how to leverage cutting-edge GPU acceleration, persistent storage, and flexible networking to maximize your research productivity within time-limited virtual machines.
