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.
