mkl, Qmkl

Tells the compiler to link to certain libraries in the
Intel® Math Kernel Library (Intel® MKL)
. On Windows systems, you must specify this option at compile time.

Syntax

Linux:
-mkl
[
=
lib
]
macOS:
-mkl
[
=
lib
]
Windows:
/Qmkl
[
:
lib
]
Arguments
lib
Indicates which
Intel® MKL
library files should be linked. Possible values are:
parallel
Tells the compiler to link using the threaded libraries in
the Intel® MKL
. This is the default if the option is specified with no
lib
.
sequential
Tells the compiler to link using the sequential libraries in
the Intel® MKL
.
cluster
Tells the compiler to link using the cluster-specific libraries and the sequential libraries in
the Intel® MKL
.
Cluster-specific libraries are not available for
macOS*
.
Default
OFF
The compiler does not link to the
Intel® MKL
.
Description
This option tells the compiler to link to certain libraries in the
Intel® Math Kernel Library (Intel® MKL)
.
On Linux*
and
macOS*
systems, dynamic linking is the default when you specify
-mkl
.
To link with
Intel® MKL
statically, you must specify:
-mkl -static-intel
On Windows* systems, static linking is the default when you specify
/Qmkl
. To link with
Intel® MKL
dynamically, you must specify:
/Qmkl /MD
For more information about using
Intel® MKL
libraries, see the article in Intel® Developer Zone titled:
Intel® Math Kernel Library Link Line Advisor
, which is located in https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor .
On Windows* systems, this option adds directives to the compiled code, which the linker then reads without further input from the driver. On Linux*
and
macOS*
systems, the driver must add the library names explicitly to the link command.
If you specify option
[Q]mkl
or
[Q]mkl=parallel
, and you also specify option
[Q]tbb
, the compiler links to the standard threaded version of the
Intel® MKL
.
However, if you specify
[Q]mkl
or
[Q]mkl=parallel
, and you also specify option
[Q]tbb
and option
[q or Q]openmp
, the compiler links to the OpenMP* threaded version of the Intel® MKL.
Alternate Options
None

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
