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
