| + | For best performance one should recompile the code for these machines, meaning one needs to tell the compiler that skylake optimization is required. How to do this varies depending on compilers. See [[https://en.wikichip.org/wiki/intel/microarchitectures/skylake_(server)#Compiler_support]] | ||
