# Accessing the System

## Requirements

- You must be a member of the **power** group
- Valid Tel Aviv University username and password
- If connecting from outside the TAU network: [TAU VPN](https://dev.hpcguide.tau.ac.il/books/getting-started/page/palo-alto-vpn "Palo Alto VPN") must be active

## Login Node

All access to the cluster is via SSH through the login node:

```bash
slurmlogin.tau.ac.il
```

Your connection is automatically load-balanced across **powerslurm-login**, **powerslurm-login2**, and **powerslurm-login3**.

## Connecting via SSH

```bash
ssh your_username@slurmlogin.tau.ac.il
```

With an SSH key:

```bash
ssh -i /path/to/your/private_key your_username@slurmlogin.tau.ac.il
```

## Important

- Do **not** run compute jobs on the login node — use `sbatch` or `srun`
- The login node is shared — heavy processes will be killed
