HOWTO: Use uv for Python at OSC

uv is a fast Python package and virtual environment manager developed by Astral. It provides functionality provided by both venv and pip, but is significantly faster at dependency resolution. Some users who do not need Conda packages or cross-language support in their project may prefer to use uv for its speed. Because uv is still under active development and its behavior may change between frequent releases, OSC does not currently provide it as a centrally managed software package.

Rolling Reboot for Security Fix

A rolling reboot is in progress to address CVE-2026-23111 for all clusters, including Ascend, Cardinal, and Pitzer. Login nodes will be rebooted first and access will be temporarily disrupted. Compute nodes will reboot in a rolling fashion; running jobs will not be impacted. See: https://www.osc.edu/resources/technical_support/known_issues/rolling_reboot_for_security_fix
