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.
On systems based on the Intel® 64 architecture, LP64 and ILP64 interfaces are available. The following table provides values to be used to set each interface 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 |
If the
mkl_set_interface_layer
function is called, the environment variable
MKL_INTERFACE_LAYER
is ignored.
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 |
Intel TBB threading
| TBB | MKL_THREADING_TBB |
If the
mkl_set_threading_layer
function is called, the environment variable
MKL_THREADING_LAYER
is ignored.
