Limitations of the Direct Call
Directly calling the
kernels has the following limitations:
Intel® oneAPI Math Kernel Library
- If theMKL_DIRECT_CALLorMKL_DIRECT_CALL_SEQmacro is used,may skip error checking.Intel® oneAPI Math Kernel LibraryWith a limited error checking, you are responsible for checking the correctness of function parameters to avoid unsafe and incorrect code execution.
- The feature is only available for the following functions:
- BLAS:?gemm,?gemm3m,?syrk,?trsm,?axpy, and?dot
- LAPACK:?getrf,?getrs,?getri,?potrf, and?geqrf. (available for C applications only)
- Verbose mode, Conditional Numerical Reproducibility, and BLAS95 interfaces are not supported.Intel® oneAPI Math Kernel Library
- GNU* Fortran compilers are not supported.
- For C applications, you must enable mixing declarations and user code by providing theoption for Intel® compilers.-std=c99
