Volta Apptainer (Container) Environment

To ensure OS compatibility for Cadence 2025 tools, Volta utilizes Apptainer to run a Rocky Linux 8 environment inside a high-performance container.

How to Launch

You do not need to call Apptainer manually. The system uses Transparent Aliasing:

Storage & Mapping

The container automatically maps host directories to ensure your files are persistent:

Host /jason → Mapped to /ventura (PDKs & Apps)
Host /home/$USER → Mapped to $HOME (Your Projects)
/tmp → Automated cleanup of lock files on unload.

Important Note on X11

Because the tools run inside a container, X11 Forwarding is mandatory. Always connect to Volta using the -X or -Y flag:

ssh -Y your_user@volta.sdsu.edu
