JupyterHub, VS Code, and RStudio
PowerPortal provides quick links to browser-based GUI applications running on the cluster. These applications run on poweride.tau.ac.il and are accessible without SSH or a VPN.
Available applications
| Application | What it is |
|---|---|
| JupyterHub | Jupyter notebooks and JupyterLab. Supports Python, R, and other kernels available on the cluster. |
| VS Code | Visual Studio Code running in the browser, connected to the cluster filesystem. Full terminal access included. |
| RStudio | RStudio Server for interactive R development and data analysis. |
Launching an application
- Click GUI Apps in the navbar.
- Select the application you want.
- The application opens in a new browser tab.
You log in with the same TAU credentials you use for PowerPortal.
Important notes
- GUI applications run on a shared login node, not on a dedicated compute node. They are intended for interactive development and light work — not for heavy computation or long-running jobs. For intensive workloads, submit a batch job through PowerPortal instead.
- Sessions are not persistent across server restarts. Save your work frequently.
- Files are stored on the same NFS home directory as the rest of the cluster — anything you create or edit in a GUI app is immediately accessible from compute nodes and vice versa.
