Parallel Overhead, Lock Contention, and

The data collected and analyzed in the
Suitability Report
window shows data for the selected site. The text that appears below
Runtime impact for this site
(lower-right area) may recommend that you consider reducing several types of parallel overhead, lock contention, and enable chunking in your parallel program, as explained in Suitability Report Overview. If you agree to address a category later by using the chosen parallel framework's capabilities or by tuning the parallel code after you have implemented parallelism, check that category.
This group of topics explain site, task, and lock overhead, lock contention, and task chunking.

Product and Performance Information


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.
