Welcome back -- we have some exciting activities to celebrate the new school year. As you settle in, don’t forget to pencil in our upcoming webinars.

Did you ever want to create a lease for a specific node? Did you ever want to create a lease that does NOT include a specific node? Ignore a node that has been reserved? Reserve a whole rack perhaps? Or just a few nodes but on the same rack? Then look no farther; here are five tips and tricks for node selection and node avoidance!

CHI-in-a-Box beta release, a new MPICH appliance, CUDA10 support for Ubuntu, and more inside! See what we've been cooking up this summer.

Chameleon PI Kate Keahey and Chameleon DevOps lead Jason Anderson will present on Monday, July 29 at the PEARC19 workshop Humans in the Loop: Enabling and Facilitating Research on Cloud Computing.

This month: a new firewall security feature for bare metal nodes, updates to official disk images, and a webinar you should take a look at if you want to learn more about wide-area layer-2 network provisioning with Chameleon!

Chameleon's DirectStitch capabilities enable isolated direct OSI layer 2 connections between tenant networks and external facilities, including other Chameleon sites.

Learn about the upgrades to the testbed we released in the run-up to the summer, including increased storage on our GPU nodes at TACC, more user-friendly options for stitching layer-2 circuits, and fully operational 100G nodes at CHI@NU!

Motivated by the opportunity to optimize the architecture of data transfer infrastructure, we recently prototyped an elastic architecture for data transfer on Chameleon Cloud in which the DTNs expand and shrink based on the demand...

I was going to make a joke about how April showers bring May flowers, but that seems to imply that April was a bad month, even if we were making it rain (or snow, as the case may have been in Chicago.) Anyhow, here’s what we’ve been up to this past month: multiple networks now allowed for nodes, complex reservations, and some major foundational upgrades!

Exploring custom high-performance drivers in specialized operating systems with an aim to scale HPC applications in order to meet the future needs of exascale computing has motivated us to build a high-performance InfiniBand driver for Nautilus (Aero-Kernel) and evaluate its performance. In this blog, we would like to share our experimental framework and results achieved.
