This blog post doesn't address how GPU "threads" can be mapped to Rust SIMD/SPMD "lanes" yet, though it hints at that. I assume that this is planned to be a topic for a future blog post.
I'd like to understand how the overall amount of "warps" to be launched on the GPU is determined. Is it fixed at shader launch, or can warps be created and destroyed on demand? If it's fixed, these are more like CPU-side "virtual processors" (in OS terminology) than true OS "threads".
