Task-Parallel Programming Model Hints

Task-parallel programming model is general-purpose. It enables you to express parallelism by enqueuing multiple tasks. You can apply this model in the following scenarios:
  • Performing different tasks concurrently by multiple threads. If you use this scenario, choose sufficient granularity of the tasks to enable good load balancing.
  • Adding an extra queue (beside the conventional data-parallel pipeline) for tasks that occur less frequently and asynchronously, such as some scheduled events.
If your tasks are independent, consider using Out-of-Order queue.

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.
