Terraform is both a command line tool, and a configuration language to build, change, and version resources from various Infrastructure as a Service (IaaS) providers. There are pre-existing
providers to integrate with major cloud platforms, both private and open-source.
In particular, since Terraform natively supports Openstack, it will also work with Chameleon :)
If you have a complex configuration, involving multiple nodes and networks, across one or more Chameleon Sites, defining them in a declarative format can be easier than creating them imperatively.
The examples from this post show how to provision instances, networks, and floating IPs across multiple Chameleon …
Best practices for using resources across multiple sites
May 1, 2023
Chameleon's resources are distributed across multiple sites. If you'd like to move your work between sites, say to take advantage of different hardware, or to find available nodes, good news! It's pretty easy, and this post spells out the details.
Interested in the Fugaku Supercomputer? We now have 8 Fugaku nodes (Fujitsu FX700), available in CHI@TACC! Each of these nodes has a 48 core ARM A64FX CPU, 32 GiB of HBM2 memory, 512GB of NVMe storage, and HDR100 Infiniband. Notably, the high-bandwidth memory and non-x86 architecture are hard to find in other systems. TACC’s Frontera Supercomputer originally procured these for evaluation, but they’re now available for general use in Chameleon.
Did you ever wonder what makes your favorite testbed “go”? The answer is CHameleon Infrastructure, or CHI for short – packaged as CHI-in-a-Box so that anybody can run their own testbed. We blogged about it a year or so ago, and a lot can change in a year, so this blog brings you some important updates. Not least, there is now a paper on CHI-in-a-Box so you can join the testbed as an Associate Site!
This year Chameleon hosted the IndySCC competition, analogous to the in-person Student Cluster Competition (SCC) of Supercomputing. Teams use cloud/shared resources to optimize a variety of HPC workloads in order to complete the most computations during a 48 hour final, all while staying below a strict power cap. Learn more about the compettion, Chameleon's support, and where you can see the results.
The recently released Chameleon Phase 3 hardware will support new experiments in networking, disaggregated hardware, and more. Learn more about the different types of hardware and what kind of experiments they're best suited for!
The Chameleon team is excited to hold our first Chameleon Hackathon event sometime in the 4th week of August or 1st week of September. This year’s hackathon will focus on reproducing and packaging experiments on the Chameleon platform. In this Call for Participations, we would like to survey Chameleon users who are interested in joining this hackathon. Please continue reading and fill out the Google form at the very end.
Join us for an introduction to CHI@Edge, Chameleon's foray into supporting experiments with edge devices, what features are implemented, and which are on the way!
