HPCC-stream performance loss with the 11.0 and 12.0 compilers

The STREAM component of the HPCC benchmark suite runs more slowly with the initial release of the 11.0 compiler compared to version 10.1. This can be worked around by disabling function inlining. The COPY component showed a similar issue in 12.0.

  • Floating-point Settings in Worker Threads May Differ from Master Thread for OpenMP, TBB and Intel Cilk Plus

    Worker threads created by OpenMP, Intel Cilk Plus or Intel Threading Building Blocks may have different initial floating-point environments compared to the master thread that spawned them. This can lead to slight differences in floating-point results.

  • Project properties changed when configuring to use Intel C++ Compiler


    Reference Number : DPD200036725, DPD200037715


    Version : 10.x


    Operating System : Windows*


    Problem Description : 
    When switching to use the Intel C++ Compiler, some project properties got changed.

    This is because in the 10.x version the IDE integration maintains all the project properties in the .icproj file. So there're times that a sync operation between .icproj and .vcproj is needed.
