On Nvidia GPUs, there is already a mechanism for this, known as local
memory, which in effect is a global region which interleaves the
various thread's data so that they can all access their fields in
This is what gets used whenever a register needs to be spilled to memory.

I do not know why Nvidia couldn't just implement TLS using this.
