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.

We were busy meeting with you all at the Chameleon User Meeting in Austin, but in between gorging ourselves on Texan BBQ and Mexican food, we conjured up some new things for you to enjoy.

We won't tell.)

Save the Planet, Use Fewer IPs

The holidays are over and you’re probably easing back into your normal pre-festivities routines. We’re happy to announce some new testbed capabilities and features to make your life (a bit) easier while you wrestle with those pesky New Year’s resolutions.

Chameleon Changelog for November 2018

Lots of SDN capability upgrades, new performance metrics, updated cloud trace data and general improvements all around! Way more fun than purging your inbox of all those Cyber Monday promo mails from sites you're pretty sure you never signed up at.
