Using MKL_DIRECT_CALL in C Applications

The following examples of code and link lines show how to activate direct calls to
Intel® oneAPI Math Kernel Library
 kernels in C applications:
  • Include the
    mkl.h
     header file: 
    #include "mkl.h" 
int main(void) {
    
// Call Intel MKL DGEMM 
    
return 0;
}
  • For multi-threaded
    Intel® oneAPI Math Kernel Library
    , compile with
    MKL_DIRECT_CALL
     preprocessor macro: 
    icc –DMKL_DIRECT_CALL -std=c99 your_application.c $(MKLROOT)/lib/intel64/libmkl_intel_lp64.a $(MKLROOT)/lib/intel64/libmkl_core.a $(MKLROOT)/lib/intel64/libmkl_intel_thread.a -lpthread –lm -openmp -I$(MKLROOT)/include
  • To use
    Intel® oneAPI Math Kernel Library
     in the sequential mode, compile with
    MKL_DIRECT_CALL_SEQ
     preprocessor macro: 
    icc –DMKL_DIRECT_CALL_SEQ -std=c99 your_application.c $(MKLROOT)/lib/intel64/libmkl_intel_lp64.a $(MKLROOT)/lib/intel64/libmkl_core.a $(MKLROOT)/lib/intel64/libmkl_sequential.a -lpthread –lm -I$(MKLROOT)/include
