WebApr 10, 2024 · Communication between threads is via memory, so code on that other core (or thread) has to run instructions that store values in to memory where it's visible. AVX-512 is not special in any way for this; k0-7 and zmm0-31 mask and vector registers are thread-private just like integer regs and mm0-7, ymm0-16. Your process is running on just one core.
