Role fact_workspace_info

Summary

Makes information about the workspace and CO available as Ansible facts. Provides three facts:

fact_workspace_info – Dict. Object containing info about the workspace (CO, user endpoint URL, etc.)/
fact_desktop_workspace – Boolean. True if the workspace has a desktop environment.
fact_workspace_storage – List. List of Strings of paths to ResearchCloud storage volumes mounted on the workspace.
fact_src_ansible_venv – string path to the python environment currently being used by Ansible. Can be used to install additional pip dependencies for Ansible modules into the correct environment. Empty string if Ansible is not using a virtual environment (but instead the global system python environment).
fact_workspace_gpus: List. Contains dicts describing available GPUs. Obtained using the lshw -class display command, filtering on descriptions containing ‘3d’ (this works at least for NVIDIA GPUs, untested with others).
fact_workspace_has_gpu: Boolean. Whether the workspace has any GPUs (convenience fact determined on the basis of fact_workspace_gpus).
fact_cuda_version: String. CUDA release version (e.g. 13.2), or empty.
fact_all_graphics_cards: String. Fact listing all graphics cards (whether GPU or not). Mostly for internal use in the role, to find GPUs.

Requires

Linux flavor operating system.
