A configurable experimental environment for large-scale edge to cloud research

Join us at the CARLA Latin America High Performance Computing Conference for the keynote presentation by Kate Keahey, Scientist at Argonne National Laboratory and University of Chicago. Kate will deliver her keynote, “Infrastructure for New Ideas,” at 9:10 AM on Thursday in the Talk of the Town venue. Don’t miss this opportunity to learn about building scientific instruments for computer science innovation and hear insights from the leader of the Chameleon project.

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 by emulating the next-generation environment on Chameleon's bare-metal servers.
