OpenGL Compute Shaders?

[asiermarzo]

Dear author and community,

What are your thoughts on using just OpenGL Compute shaders?

We are running FDTD simulations and having tested JAX, raw cuda, cupy, numba... Compute Shaders seem the best option, even above my beloved OpenCL.

Advantages:

• Leightweight and easier to install, could even run on a browser with WebGL.
• modifiying Texture3Ds in place rather than having to make copies.
• Bilinear and 2D texture cache for free. Anyone can confirm 3D texture cache?

On the other hand, we lose the options to run in TPUs, CPUs and other OpenCL stuff but I think it is worthy.

Best,
Asier.
