Login Nodes vs. Compute Nodes

TLDR

use the login node to set up a job, but do heavy computation on compute nodes

When you login to Turing, you're connected to a login node. Think of the login node as the front desk of a large computational facility:

🖥️ Login Node

• Purpose: Meant for lightweight tasks such as:
• Editing files
• Compiling code
• Submitting jobs to the scheduler
• 🚫 Important: Do not run heavy computations here. It is innefecient and can make it harder for others to use turing.

🏭 Compute Nodes

• Purpose: The powerhouse where your computational jobs are executed.
• Access: Not directly accessible via SSH, instead, jobs are sent here through the job scheduler, SLURM.
