multigpu_diffusion_comfyui

ComfyUI nodes to run multigpu_diffusion. (Basically, a ComfyUI front-end to Diffusers, with support for multi-GPU environments.)

Notes:

• Does not (and will never) use native sampling.
• Windows and macOS are (probably) not supported.
• This node uses psutil/subprocess to manage the host scripts. You can find the calls in modules/host_manager.py.

Usage:

1. If applicable, activate your ComfyUI venv.
2. cd to custom_nodes/multigpu_diffusion_comfyui.
3. (Review and) run setup.sh.

Debugging:

• If you run into issues, you can manually curl to the hosts (e.g., curl localhost:{port}/close to manually shut down the host).

Test Environment:

• ComfyUI 0.9.1
• 4x Nvidia Tesla T4
• Ubuntu Server 26.04
• Python 3.14.4
