Overview
what PowerPortal is, how to log in, interface tour (navbar, tabs)
Getting Started with PowerPortal
PowerPortal is a web interface for the TAU HPC cluster. It lets you submit batch jobs to Slurm, monitor running and completed jobs, browse output files, and launch GUI applications — all without using the command line.
What you can do
- Submit jobs — fill out a form to configure resources (partition, CPUs, memory, GPUs, time limit) and paste your script. No need to write an sbatch file manually.
- Monitor jobs — see live job state, allocated nodes, and exit codes. Poll job output directly in the browser.
- Save templates — reuse common job configurations without re-entering every field.
- View fair-share — check your group's current usage and priority.
- Launch GUI apps — open JupyterHub, VS Code, or RStudio in one click.
What PowerPortal does not do
- It does not replace SSH. For interactive sessions,
salloc, or file transfers, use the cluster directly. - It does not manage software modules. Load modules inside your job script with
module load.
Access
PowerPortal is available at https://powerportal.tau.ac.il. Access requires an active TAU account and membership in the power user group. Contact HPC support to request access.
Logging in to PowerPortal
PowerPortal uses your TAU university credentials — the same username and password you use for TAU email and other university systems.
Steps
- Go to https://powerportal.tau.ac.il.
- Enter your TAU username (e.g.
jsmith) and password. - Click Sign in.
Your session stays active for 4 hours. Activity resets the timer — if you close the browser and return within 4 hours, you will still be logged in.
Forgot your password?
Use the TAU self-service password reset portal: https://pass.tau.ac.il/sspr/public/forgottenpassword. There is also a link to this page on the login screen and in Account Settings.
Access denied?
If your credentials are correct but login fails, your account may not be in the power group. Contact HPC support at hpc@tauex.tau.ac.il to request access.
Too many failed attempts
After 10 consecutive failed login attempts from the same IP address, that address is locked out for 1 hour. If you are locked out, wait an hour or contact HPC support to reset the lockout early.
Navigating the Interface
After logging in you land on the Jobs page. The navigation bar at the top is present on every page.

Jobs page layout
The Jobs page has three tabs:
- My Active Jobs — jobs submitted under your username, active and recent.
- Cluster Queue — all jobs currently on the cluster, visible to staff only.
- Job Search — search historical and active jobs by ID, name, user, state, or partition.
Click any job row to open the detail dialog, which shows full resource allocation, the submit host, and buttons to view output or cancel the job.
