In that case, I would not say Legacy code is sequential. For the past few decades, SMP has been the target where sensible/possible. &gt; At a fine-grained level, our compilers vectorize (i.e. parallelize) our code. Vectorization is a hardware optimization designed for a very specific use-case: Performing instruction f N times on a buffer of f_input x N, by replacing N instantiations of f by a single fN instance. If this is parallelization, then an Intel Skylake processor…</p><p><a href="https://hackerpaper.kaipfister.de/p/1110.4623/">Paper and discussion history</a>. A mention is not an endorsement.</p>cs.OS
