# GUI Applications

JupyterHub, VS Code, RStudio via PowerIDE (links + brief description)

# 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

<table id="bkmrk-application-what-it-"><thead><tr><th>Application</th><th>What it is</th></tr></thead><tbody><tr><td>**JupyterHub**</td><td>Jupyter notebooks and JupyterLab. Supports Python, R, and other kernels available on the cluster.</td></tr><tr><td>**VS Code**</td><td>Visual Studio Code running in the browser, connected to the cluster filesystem. Full terminal access included.</td></tr><tr><td>**RStudio**</td><td>RStudio Server for interactive R development and data analysis.</td></tr></tbody></table>

## Launching an application

1. Click **GUI Apps** in the navbar.
2. Select the application you want.
3. 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.
