Five Ways to Get What You Want on Chameleon

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!

Chameleon Changelog for June 2019

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 Changelog for May 2019

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!

Towards an Elastic Data Transfer Infrastructure

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...

Chameleon Changelog for April 2019

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 InfiniBand Drivers for Specialized OS Kernels

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.
