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.
Many things can go wrong when deploying a large cluster of nodes. We thought it would be helpful for some of you to include some useful tips and tricks for deploying 20+ node clusters when some of the nodes may cause you problems.
Happy April 1st! Did we really replace all of our nodes with GPUs? I'm afraid that such news is unsubstantiated and we'll get to the bottom of who is spreading such rumors. However, we have some cool new features around our object storage and floating (public) IPs, and some information about upcoming big changes inside.
Have you ever lost your data after your instance failed, or are your instances failing to launch with a custom image? You may be handling your data incorrectly in the cloud. Read on to learn how to keep your data persistent and your custom images small.
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. (If you typically stop reading at the summary, then just skip to filling out our new user survey for 2019, which will help us prioritize what shiny new hardware to purchase and what features to work on. We won't tell.)
IPv4 address exhaustion, along with natural resources depletion and global warming, has long been recognized as one of the greatest environmental threats facing humanity. Read on to learn how to keep floating IPs afloat!
To help you start the year off on the right foot we offer lots of improvements in VLAN management, experiment automation, and usability. And we are really looking forward to meeting many of you at the User Meeting in Austin next week and discussing all the innovations in person!
