Allows dispatching Intel® Advanced Vector Extensions.
Syntax
Fortran:
irc = mkl_enable_instructions(MKL_AVX_ENABLE)
C:
irc = mkl_enable_instructions(MKL_AVX_ENABLE);
Include Files
The FORTRAN 77 interface is specified in the mkl_service.fi include file and the C interface is specified in the mkl_service.h include file.
Input Parameters
MKL_AVX_ENABLE |
Parameter indicating which new instructions the user needs to enable. |
Output Parameters

Description
This function is currently void and deprecated but can be used in future Intel MKL releases.
Note
Always remember to add #include "mkl.h" to use the C usage syntax.
Optimization Notice |
|---|
|
The Intel® Math Kernel Library (Intel® MKL) contains functions that are more highly optimized for Intel microprocessors than for other microprocessors. While the functions in Intel® MKL offer optimizations for both Intel and Intel-compatible microprocessors, depending on your code and other factors, you will likely get extra performance on Intel microprocessors. While the paragraph above describes the basic optimization approach for Intel® MKL as a whole, the library may or may not be optimized to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include Intel® Streaming SIMD Extensions 2 (Intel® SSE2), Intel® Streaming SIMD Extensions 3 (Intel® SSE3), and Supplemental Streaming SIMD Extensions 3 (Intel® SSSE3) instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Intel recommends that you evaluate other library products to determine which best meets your requirements. |
