Accessing astro3

How to get access and connect to the astro3 cluster over SSH.

Requirements

• Must be a member of the physics_astro3 LDAP group
• Valid Tel Aviv University username and password
• If connecting from outside the TAU network: TAU VPN must be active — see Palo Alto VPN

Login Node

Direct SSH to the astro3 head node — no load-balanced login pool like powerslurm:

astro3.tau.ac.il

Connecting via SSH

ssh your_username@astro3.tau.ac.il

With an SSH key:

ssh -i /path/to/your/private_key your_username@astro3.tau.ac.il

Important

• Do not run compute jobs directly on the head node — use sbatch or srun
• The head node is shared — heavy processes may be killed
