AImageLab SRV

Remote debugging via Desktop IDE

---

AImageLab provides development GPUs that can be used via remote debugging. Hosts containing development GPUs replicate the same configuration of all aimagelab-srv nodes.

All AImageLab-SRV users can access the development GPUs. The development resources are managed by SLURM, within the partition all_serial. To access them, you always need to specify one account. To get the list of accounts assigned to your username, run the susage command.

Usage from shell

⚠️ Warning: It is forbidden to access GPUs and/or use heavy resources on login nodes without going through the SLURM scheduler.

To get a shell with a development GPU, use the following command from the login node or a development node:

srun --partition=all_serial --account=<account> --gres=gpu:1 --pty bash

Debugging via Desktop IDE

Visual Studio Code

• From the tab Extensions, install extensions Remote - SSH and Remote - SSH: Editing Configuration Files
• Connect to a frontend node (e.g.: F1, Remote-SSH: Connect to Host...) and enter your project folder (e.g. via: F1, File: Open Folder...)
• From the tab Extensions, on the remote host install the extensions Python and Pylance
• Create a file bash.sh in the root of your project, containing the following:
  srun -Q --immediate=10 -w <host> --partition=all_serial --account=<account> --gres=gpu:1 --time 60:00 --pty bash
  where host is the frontend node to which you are connected.
• Check that the file has execute permissions. Otherwise run chmod u+x bash.sh
• Open (or create) .vscode/settings.json from your project root, and make sure it contains the following key-value pair:
  "terminal.integrated.automationProfile.linux": { "path": "$projectFolder/bash.sh" }
• Restart VSCode, connect again to the same frontend node, open your project.
• You can now start debugging!
