Input Parameters

Name	Type	Description
required_interface	INTEGER	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

required_interface

INTEGER

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_layerfunction 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 exceptmkl_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
INTEGER	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.
