Intel® oneAPI Math Kernel Library Developer Reference - C
Returns the frequency value in GHz based on constant-rate Time Stamp Counter.
double mkl_get_clocks_frequency (void);
The function mkl_get_clocks_frequency returns the CPU frequency value (in GHz) based on constant-rate Time Stamp Counter (TSC). Use of the constant-rate TSC ensures that each clock tick is constant even if the CPU frequency changes. Therefore, the returned frequency is constant.
Obtaining the frequency may take some time when mkl_get_clocks_frequency is called for the first time. The same holds for functions second/dsecnd, which call mkl_get_clocks_frequency.
