Getting Started Guide

VPN Required: All connections to the HPC cluster must be made through the university VPN.

Initial Setup Process

1

Request Account

Contact your Principal Investigator (PI) or lab administrator to request an HPC account. You will need to provide:

  • Your university email address
  • Project/lab affiliation
  • Estimated resource requirements
2

Connect to VPN

Before accessing any HPC resources, connect to the university VPN:

# Contact your IT department for VPN credentials and configuration # Typical connection (varies by setup): openconnect vpn.university.edu
3

Set Your Password

Once your account is created, you will receive a password reset email:

  1. Check your email for the reset link
  2. Click the link and set a strong password (min 10 characters)
  3. Important: Add your SSH public key during this step
The SSH key allows passwordless login. Generate one with: ssh-keygen -t ed25519 -C "your_email@uj.edu.pl"
4

Connect via SSH

After setting up your password and SSH key, connect to the cluster:

# Connect to login node ssh your_username@hpc.psychologia.uj.edu.pl # Or with explicit key ssh -i ~/.ssh/id_ed25519 your_username@hpc.psychologia.uj.edu.pl
5

Explore Your Environment

Once logged in, you'll find:

# Your home directory (backed up, limited quota) ~/home/username # Project directories (shared with your lab) ~/projects/project_name # Scratch space (fast, not backed up, use for temp files) ~/scratch # Check your quota quota -s
