Interesting statistics on vectorization for Skylake avx512 (i9-7900) - 8.1 vs. 7.3.

Consider the attached Fortran code (the most expensive routine, computation-wise, in our weather forecasting model). verint.s.7.3 is the result of: gfortran -g -O3 -S -march=native -mtune=native verint.f using release 7.3. verint.s.8.1 is the result of: gfortran -g -O3 -S -march=native
