Tuning Methodology

When optimizing your code for parallel hardware, consider using the following iterative approach:
Tuning methodology for code optimization (parallel hardware)
Ignore the top two elements if you are not running on a cluster. There is not a recommended start point what to optimize first as this may vary. Pop up a level, look at all the potential optimizations and see where you can get the biggest gain for the least work. That is where you want to start.

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. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
