Power to People: Monitoring Power Consumption of Low Power Nodes

 

Did you ever wonder how much power was consumed by executing a program? The Chameleon team recently implemented a feature that automatically collects power usage data on all low power nodes in the system. Instantaneous power usage data (in watts) are collected through the IPMI interface on the chassis controller for the nodes. This “out-of-band” approach does not consume additional power on the node itself and runs even when the node is powered off. Low power nodes for which power usage data are now being collected include all Intel Atoms, low power Xeons, and ARM64s. In this blog post we ...

ENOS: a Framework for Experimenting with OpenStack

ENOS is an integrated framework that facilitates experimenting with OpenStack. ENOS allows researchers to easily express different configurations, enabling fine-grained investigations of OpenStack services. ENOS collects performance metrics at runtime and stores them for post-mortem analysis and sharing.

Chameleon Changelog for May 2018

Great news in Chameleon-land!

I hope everybody is enjoying the nice weather and hopefully a more relaxed schedule for the summer! Read on to find out what we’ve been up to last month.

Chameleon Changelog for April 2018

Great news in Chameleon-land!

 

Here are the most important features we added since the public release of our new hardware in mid-March:

How to Make the Most of your Seven Day Lease

Did you ever find yourself spending half of your 7 day lease iterating on the environment configuration for your experiment and worried that the remaining 4 days are not enough to run it? If so read on: we are aware that configuring your experimental environment can be a bit of a journey and have packed the system with tools and features that will make it smoother.

Metrics using Gnocchi

One of Chameleon's newest features is metrics using Gnocchi. In this post, we will cover how to quickly get started with Gnocchi, including how to access collected metrics and customize which metrics are reported from your Chameleon instances.

Orchestrating and Deploying Complex Appliances

If you are a distributed systems, networking or HPC researcher, you may be interested in Chameleon's Orchestration capabilities. Orchestration allows you to perform "one click" deployment of Complex Appliances - clusters of bare metal machines with user defined networking.

Making Instance Snapshots on Chameleon

Now that you have successfully launched a Chameleon instance, you may want to take a snapshot of it. Snapshots are a great way of saving your work in progress, especially if you have done a lot of configuration to your bare metal instance and you need to preserve the work beyond your lease.
