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.
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 |
---|---|---|
Intel threading, default |
INTEL |
MKL_THREADING_INTEL |
Sequential mode of Intel® oneAPI Math Kernel Library |
SEQUENTIAL |
MKL_THREADING_SEQUENTIAL |
GNU threading† |

MKL_THREADING_GNU |
PGI threading† |

MKL_THREADING_TBB |
† 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.
