Wow, this is such a cool idea. Translating regular instructions to SIMD instructions in order to run 16 copies of the same program at once, for fuzzing!https://gamozolabs.github.io/fuzzing/2018/10/14/vectorized_emulation.html …

Isn’t that pretty much exactly Larrabee though? Larrabee was a separate chip rather than on-die, and its 512-bit instructions were slightly different from AVX-512, but other than that it’s the same idea. I guess a new attempt could be less minimalist wrt graphics-specific HW.

Well, I don’t see the point of having two vector ISAs (Gen) and SIMD (AVX-512) that largely overlap in functionality but are just incompatible, are programmer-exposed, and ship on the same die.
