Your application calls serialized versions of math functions when you use the precise floating point model. To fix: Do one of the following:

• Add fast-transcendentals compiler option to replace calls to transcendental functions with faster calls.

  Windows* OS	Linux* OS
  /Qfast-transcendentals	-fast-transcendentals

  CAUTION: This may reduce floating point accuracy.

• Enforce vectorization of the source loop using a directive: #pragma omp simd

Example

...
#pragma omp simd
for (i=0; i<n; i++)
...

void add_floats(float *a, float *b, float *c, float *d, float *e, int n)
{
    int i;
    #pragma omp simd
    for (i=0; i<n; i++)
    {
        a[i] = a[i] + b[i] + c[i] + d[i] + e[i];
    }
}
