I tried to use Intel Advisor to vectorise my program. and it tells me that the compiler con not vectorise some loops because it contain _powr8i4 which correspond to x**i (x:double precision and i:integer).
Why did not intel Fortran Compiler come with a vectorized version of _powr8i4 (or generally power function)?
and How to vectorise it (other than using MKL)?
NB: I did use the most aggressive optimization flags : /O3 /QxHost /Qipo /fp:fast=2
