SPMD is conceptually more like a job system, so this generates code that is not necessarily all executing same code in lockstep. SPMD/SIMD is "single program" vs "single instruction". The compiler does also exploit SIMD but that's orthogonal to the SPMD concept. reference: https://ispc.github.io/ispc.html#the-ispc-parallel-execution-model https://ispc.github.io/ispc.html#the-ispc-parallel-execution...
