In fact, theĭegree of speedup is a good measure of how well array basedĬalculations are coded: good CFD applications will typically get anĪVX speedup factor of about 1.8, whereas the (more (independent of which instruction set you're using). Performance boost per processor generation for that reason Systems of the various processor generations, giving a further 5-10% Note that Intel and AMD have also improved the memory
Less than that (due to the fact that these codes are so bottleneckedīy main-memory operations that improving the arithmetic doesn't help Because of its sloppyĬoding, WRF will get less than half that much speedup, and CMAQ even Performance boost for using SSE4.2 instructions, a further 70-80%īoost for AVX, and a further 25-30% for AVX2. Well designed modeling codes will get approximately a 20-25% Of instructions (but not, of course, vice versa).
