Dynamically Selecting the Interface and Threading Layer
The Single Dynamic Library (SDL) enables you to dynamically select the interface and threading layer for
.
Intel® oneAPI Math Kernel Library
Setting the Interface Layer
To set the interface layer at run time, use the
mkl_set_interface_layer
function or the
MKL_INTERFACE_LAYER
environment variable.
Available interface layers depend on the architecture of your system.
The following table lists available interface layers for Intel® 64 architecture along with the values to be used to set each layer.
Interface Layer
| Value of
MKL_INTERFACE_LAYER | Value of the Parameter of
mkl_set_interface_layer |
---|---|---|
Intel LP64, default
| LP64 | MKL_INTERFACE_LP64 |
Intel ILP64
| ILP64 | MKL_INTERFACE_ILP64 |
GNU* LP64
| GNU,LP64 | MKL_INTERFACE_LP64+MKL_INTERFACE_GNU |
GNU ILP64
| GNU,ILP64 | MKL_INTERFACE_ILP64+MKL_INTERFACE_GNU |
If the
mkl_set_interface_layer
function is called, the environment variable
MKL_INTERFACE_LAYER
is ignored.
See the
Developer Reference for details of the
Intel® oneAPI Math Kernel Library
mkl_set_interface_layer
function.
The following table lists available interface layers for IA-32 architecture along with the values to be used to set each layer.
Interface Layer
| Value of
MKL_INTERFACE_LAYER | Value of the Parameter of
mkl_set_interface_layer |
---|---|---|
Intel, default
| LP64 | MKL_INTERFACE_LP64 |
GNU
| GNU,LP64 or
GNU | MKL_INTERFACE_LP64+MKL_INTERFACE_GNU or
MKL_INTERFACE_GNU |
Setting the Threading Layer
To set the threading layer at run time, use the
mkl_set_threading_layer
function or the
MKL_THREADING_LAYER
environment variable. The following table lists available threading layers along with the values to be used to set each layer.
Threading Layer
| Value of
MKL_THREADING_LAYER | Value of the Parameter of
mkl_set_threading_layer |

Not supported by the SDL for Intel® Many Integrated Core Architecture.
If the
mkl_set_threading_layer
function is called, the environment variable
MKL_THREADING_LAYER
is ignored.

Developer Reference for details of the
Intel® oneAPI Math Kernel Library
mkl_set_threading_layer
function.
