Chameleon Supported Images

There are a number of images built and supported by the Chameleon team, specifically:

  • CC-Ubuntu24.04

  • CC-Ubuntu24.04-CUDA

  • CC-Ubuntu24.04-ROCm

  • CC-Ubuntu24.04-ARM64

  • CC-Ubuntu22.04

  • CC-Ubuntu22.04-CUDA

  • CC-Ubuntu22.04-ARM64

  • CC-Centos9-Stream

The CUDA images, such as Ubuntu24.04-CUDA, contain various settings, software, and drivers specifically for NVIDIA GPU nodes. The ROCm images contain similar settings, software, and drivers for AMD GPU nodes. And finally, the ARM64 images, such as Ubuntu22.04-ARM64, are images specifically built with ARM support for ARM nodes. Non-ARM images all assume x86-based architectures.

Warning

Any images with operating system versions that are end-of-life, such as Ubuntu18.04 are no longer offered as Chameleon-supported images. However, they can still be used on Chameleon with caution. Please note that these images are EOL so they no longer receive security updates and bug fixes. They may stop working at any point, therefore, make sure to upgrade and move your environments to newer versions of the operating system as soon as possible. If you do need to launch older images on Chameleon, please consider using a bastion host that is up-to-date and provides SSH access. From there, you can jump to your instances running older images that are not exposed directly on the Internet.

You may also build your own images and share them with the community. These images may be built from scratch or based on the Chameleon-supported images. However, the Chameleon team cannot offer support for user-provided images.
