Chameleon Supported Images
There are a number of images built and supported by the Chameleon team, specifically:
CC-Ubuntu26.04
CC-Ubuntu24.04
CC-Ubuntu24.04-CUDA
CC-Ubuntu24.04-CUDA-VGPU
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 CC-Ubuntu24.04-CUDA-VGPU image is a variant of
the CUDA image for virtual GPU (vGPU) nodes at KVM@TACC. It is intended for
use with the g1.h100.vgpu.1g.12gb flavor and comes pre-configured with the
appropriate vGPU license. The ROCm images contain similar settings, software,
and drivers for AMD GPU nodes. And finally, the ARM64 images, such as
Ubuntu24.04-ARM64,
are images specifically built with ARM support for ARM nodes. Non-ARM
images all assume x86-based architectures. All Chameleon-supported images can
be found on Trovi under the appliance tag.
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.
