Using the
/Q
mkl Compiler Option

The Intel®
Parallel Studio XE Composer Edition
 compiler supports the following variants of the
/Q
mkl
 compiler option:
/Q
mkl
 or
/Qmkl:parallel
to link with a certain
Intel® oneAPI Math Kernel Library
 threading layer depending on the threading option provided:
  • For
    -qopenmp
     the OpenMP threading layer for Intel compilers
  • For
    -tbb
     the Intel® Threading Building Blocks (Intel® TBB) threading layer
/Qmkl:sequential
to link with sequential version of
Intel® oneAPI Math Kernel Library
.
/Qmkl:cluster
to link with
Intel® oneAPI Math Kernel Library
 cluster components (sequential) that use Intel MPI.
The
-qopenmp
 option has higher priority than
-tbb
in choosing the
Intel® oneAPI Math Kernel Library
 threading layer for linking.
For more information on the
/Q
mkl
 compiler option, see the Intel Compiler User and Reference Guides.
For each variant of the
/Qmkl
 option, the compiler links your application using the following conventions:
  • cdecl for the IA-32 architecture
  • LP64 for the Intel® 64 architecture
If you specify any variant of the
/Q
mkl
 compiler option, the compiler automatically includes the
Intel® oneAPI Math Kernel Library
 libraries. In cases not covered by the option, use the Link-line Advisor or see Linking in Detail.
