C:

freq = mkl_get_clocks_frequency();

Output Parameters

Description

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.

Note

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.
