Original PR: https://github.com/Comfy-Org/desktop/pull/1088
Author: @benceruleanlu
Created: 4/15/2025
Status: ❌ Closed

Base: main ← Head: blackwell

📄 Description

~~Adds new compiled requirements, which is fetched instead of the normal one if user is on Blackwell architecture as reported by a parsed nvidia-smi -q command.~~

~~I couldn't find a way to fetch architecture directly with nvidia-smi, only through -q and parsing the response.~~

Implementation plan: Check if blackwell on frontend side, change default torchMirror to 12.8, then actually use installOptions.torchMirror on desktop side instead of depending on installOptions.device as the code currently is.

Related: #1077
