Hi all,

I have simple idea. When I turned on OpenMP, for parallelly execute simple
for it's enough when I add line like this before loop:
#pragma omp parallel for
for (size_t i = 0; i < 1000000; i++)
vec_c[i] = vec_a[i] * vec_b[i];
Why don't use similar idea for show compiler that, it can by done by SIMD
CPU extension? e.g.
#pragma simd for
Use
#pragma omp simd
for that.
That is part of OpenMP for years.
