mkl_set_interface_layer
(
int
required_interface
);

Input Parameters
Name
Type
Description
required_interface
int
Determines the interface layer. Possible values depend on the system architecture. Some of the values are only available on Linux* OS:
  • Intel® 64 architecture:
    MKL_INTERFACE_LP64
     for the Intel LP64 interface.
    MKL_INTERFACE_ILP64
     for the Intel ILP64 interface.
    MKL_INTERFACE_LP64+MKL_INTERFACE_GNU
     for the GNU* LP64 interface on Linux OS.
    MKL_INTERFACE_ILP64+MKL_INTERFACE_GNU
     for the GNU ILP64 interface on Linux OS.
  • IA-32 architecture:
    MKL_INTERFACE_LP64
     for the Intel interface on Linux OS.
    MKL_INTERFACE_LP64+MKL_INTERFACE_GNU
     or
    MKL_INTERFACE_GNU
     for the GNU interface on Linux OS.
Description
If you are using the Single Dynamic Library (SDL), the
mkl_set_interface_layer
function sets the specified interface layer for
Intel® oneAPI Math Kernel Library
 at run time.
Call this function prior to calling any other
Intel® oneAPI Math Kernel Library
 function in your application except
mkl_set_threading_layer
. You can call
mkl_set_interface_layer
 and
mkl_set_threading_layer
 in any order.
The
mkl_set_interface_layer
 function takes precedence over the
MKL_INTERFACE_LAYER
 environment variable.
See
Intel® oneAPI Math Kernel Library
 Developer Guide
 for the layered model concept and usage details of the SDL.
Return Values
Type
Description
int
  • Current interface layer if it is set in a call to
    mkl_set_interface_layer
     or specified by environment variables or defaults.
    Possible values are specified in Input Parameters.
  • -1, if the layer was not specified prior to the call and the input parameter is incorrect.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and 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. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
