Science IT provides Open OnDemand (OOD), a browser-based portal for Lawrencium. With OOD you can manage files, open a shell, monitor jobs and launch interactive applications from a web browser, without installing any client software.
Features
- File management: upload, download, move, rename and delete files and folders. For large transfers, use Globus.
- File editor: edit and save files without opening a shell.
- Shell access: open a command-line shell on Lawrencium from the portal.
- Job monitoring: view and manage your active Slurm jobs.
- Interactive applications: launch Jupyter, RStudio, MATLAB, VS Code and Ray Cluster on Lawrencium compute nodes.
- Remote desktop: run a full XFCE Linux desktop on a compute node for GUI-heavy work, with all rendering done on the cluster, so no local X server is needed.
- AI tools: run local LLMs with Ollama inside Jupyter and VS Code. See Ollama with Jupyter and VS Code.
Getting started
Go to lrc-ondemand.lbl.gov and sign in through CILogon with your Berkeley Lab identity. You need a Lawrencium user account; see User Accounts.
Interactive sessions run as Slurm jobs and are charged service units like any other job. A session keeps running, and keeps being charged, until it ends or you delete it, even if you close your browser.
For step-by-step instructions, app details, SU charges and troubleshooting, see the Open OnDemand documentation.
