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.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
.Return Values
