qmkl, Qmkl

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

Syntax

Linux:
-qmkl
[
=
lib
]
Windows:
/Qmkl
[
:
lib
]
Arguments
lib
Indicates which
oneMKL
library files should be linked. Possible values are:
parallel
Tells the compiler to link using the threaded libraries in
oneMKL
. This is the default if the option is specified with no
lib
.
sequential
Tells the compiler to link using the sequential libraries in
oneMKL
.
cluster
Tells the compiler to link using the cluster-specific libraries and the sequential libraries in
oneMKL
.
Default
OFF
The compiler does not link to the
oneMKL
library.
Description
This option tells the compiler to link to certain libraries in the
Intel® oneAPI Math Kernel Library
(
oneMKL
)
.
On Linux* systems, dynamic linking is the default when you specify
-qmkl
.
On C++ systems, to link with
oneMKL
statically, you must specify:
-qmkl -static-intel
On Windows* systems, static linking is the default when you specify
/Qmkl
. To link with
oneMKL
dynamically, you must specify:
/Qmkl /MD
For more information about using
oneMKL
libraries, see the article in Intel® Developer Zone titled:
Intel® oneAPI Math Kernel Library Link Line Advisor
, which is located in https://software.intel.com/content/www/us/en/develop/tools/oneapi/components/onemkl/link-line-advisor.html.
On Windows* systems, this option adds directives to the compiled code, which the linker then reads without further input from the driver. On Linux* systems, the driver must add the library names explicitly to the link command.
If you specify option
[q or Q]mkl
, or
-qmkl=parallel
or
/Qmkl:parallel
, and you also specify option
[Q]tbb
, the compiler links to the standard threaded version of
oneMKL
.
However, if you specify
[q or Q]mkl
, or
-qmkl=parallel
or
/Qmkl:parallel
, and you also specify option
[Q]tbb
and option
[q or Q]openmp
, the compiler links to the OpenMP* threaded version of
oneMKL
.
