Accelerating Loop Heavy Code with a GPGPU Lib

Curious if anyone knows of some good candidate blocks of code in the codebase to slap something like GitHub - gpujs/gpu.js: GPU Accelerated JavaScript into it. These kind of libraries either take in GLSL code or call toString()
on passed in / registered functions, compile them, and then run them in parallel on the GPU.

They offer a sweet API to do some high-performance computing in javascript.

This is kind of related with webassembly questions. We do not have frame long processing unfortunately.
The overweight added by communicating with the shader is not really worht it.

Only places where I could see it use would be there perhaps: Babylon.js/meshSimplification.ts at master · BabylonJS/Babylon.js · GitHub
