The Nyx cluster is our experimental cluster used to:

• test new hardware
• test puppet manifests / new cluster tools or operations prior to an application to one of the Chaos or Gaia cluster.

It is composed of the following computing elements:

For instance, we are currently testing cutting-edge high-density computing enclosures based on low-power ARM CortexA9 processors (4C, 1.1GHz). The 2 Boston Viridis enclosures we are experimenting with feature 96 ARM-Cortex A9 processors (thus offering a total of 384 cores). Assuming our tests are successful, these nodes will also be part of the Gaia cluster.
