Task Patterns

To summarize:
  • You choose
    parallel sites
    in your program.
  • You choose
    tasks
    in your parallel sites.
  • Tasks in a parallel site can execute in parallel with one another and with tasks in an outer parallel site, but not in parallel with tasks in unrelated parallel sites.
You are free to arrange your sites and tasks any way that you want, but there are several simple, common patterns that you will probably want to use.
The following sections describe the process of identifying task patterns, as well as information about data parallelism and task parallelism.

Product and Performance Information

1

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 reserverd 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.
