Difficult Problems: Choosing a Different Set of Tasks

If you find a conflict that cannot be resolved using the above techniques, you should consider the following alternatives.
  • Merge the two tasks involved in the conflict into a single task.
  • Divide the tasks into smaller tasks and do the work preceding the conflict in parallel, the work involving the conflict serially, and the work after the conflict in parallel.
  • Find a different site to introduce parallelism.
  • Intel Advisor
    presents a simplified model of what is possible with parallel programming. Occasionally it will be beneficial to take advantage of more advanced techniques that are available in the
    Intel® Threading Building Blocks (Intel® TBB)
    , OpenMP*, or native threading APIs.
Any changes - other than lock annotations - you have made to fix incidental sharing problems should be left in the code. These changes will not harm performance, they have improved maintainability, and they may be useful at the new site or in future parallelization efforts.

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 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.
