Output Parameters

Description

The mkl_get_cpu_clocks function returns the elapsed CPU clocks.

This may be useful when timing short intervals with high resolution. The mkl_get_cpu_clocks function is also applied in pairs like second/dsecnd. Note that out-of-order code execution on IA-32 or Intel® 64 architecture processors may disturb the exact elapsed CPU clocks value a little bit, which may be important while measuring extremely short time intervals.
