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.
Note
getcpuclocks is an obsolete name for the mkl_get_cpu_clocks function that is referenced in the library for back compatibility purposes but is deprecated and subject to removal in subsequent releases.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors.
