Issue: Inefficient processing of SIMD-enabled functions possible

Vector declaration defaults for your SIMD-enabled functions may result in extra computations or ineffective memory access patterns. Improve performance by overriding defaults.

Recommendation: Target a specific processor type

The default instruction set architecture (ISA) for SIMD-enabled functions is inefficient for your host processor because it could result in extra memory operations between registers. To fix: Do one of the following to add a processor clause to your vector declaration.

Add processor(cpuid) to your #pragma omp declare simd directive.
For Windows* OS: Add processor(cpuid ) to your _declspec(vector()) declaration.
For Linux* OS: Add processor(cpuid) to your _attribute_(vector()) declaration.
