stable-diffusion-webui-distributed

This extension enables you to chain multiple webui instances together for txt2img and img2img generation tasks.

For those with multi-gpu setups, yes this can be used for generation across all of those devices.

The main goal is minimizing the lag of (high batch size) requests from the main sdwui instance.

Contributions and feedback are much appreciated!

Installation

On the master instance:

• Go to the extensions tab, and swap to the "available" sub-tab. Then, search "Distributed", and hit install on this extension.

On each slave instance:

• enable the api by passing --api and ensure it is listening by using --listen
• ensure all of the models, scripts, and whatever else you think you might request from them is present\ Ie. if you're using sd-1.5 on the controlling instance, then the sd-1.5 model should also be present on each slave instance. Otherwise, the remote will fallback to some other model that is present.

if you want to easily sync models between your nodes, you might want to use something like rclone

Tips

• If benchmarking fails, try hitting the Redo benchmark button under the script's Util tab.
• If any remote is taking far too long to returns its share of the batch, you can hit the Interrupt button in the Util tab.
• If you think that a worker is being under-utilized, you can adjust the job timeout setting to be higher. However, doing this may be suboptimal in cases where the "slow" machine is actually really slow. Alternatively, you may just need to do a re-benchmark or manually edit the config.

Command-line arguments

--distributed-skip-verify-remotes Disable verification of remote worker TLS certificates (useful for if you are using self-signed certs like with auto tls-https)\ --distributed-remotes-autosave Enable auto-saving of remote worker generations\ --distributed-debug Enable debug information
