High performance implement of atomic minimal operation
问题 There is no atomic minimal operation in OpenMP, also no intrinsic in Intel MIC's instruction set. #pragmma omp critial is very insufficient in the performance. I want to know if there is a high performance implement of atomic minimal for Intel MIC. 回答1: According to the OpenMP 4.0 Specifications (Section 2.12.6), there is a lot of fast atomic minimal operations you can do by using the #pragma omp atomic construct in place of #pragma omp critical (and thereby avoid the huge overhead of its

Where should I put ANNOTATE_ITERATION_TASK?
问题 I'm using Intel Advisor to analyze my parallel application. I have this code, which is the main loop of my program and where is spent most of the time: for(size_t i=0; i<wrapperIndexes.size(); i++){ const int r = wrapperIndexes[i].r; const int c = wrapperIndexes[i].c; const float val = localWrappers[wrapperIndexes[i].i].cur.at<float>(wrapperIndexes[i].r,wrapperIndexes[i].c); if ( (val > positiveThreshold && (isMax(val, localWrappers[wrapperIndexes[i].i].cur, r, c) && isMax(val, localWrappers
icpc slower than gcc?
问题 I'm trying to make an optimized parallel version of opencv SURF and in particular surf.cpp using Intel C++ compiler. I'm using Intel Advisor to locate inefficient and unvectorized loops. In particular, it suggests to rebuild the code using the icpc compiler (instead of gcc ) and then to use the xCORE-AVX2 flag since it's available for my hardware. So my original cmake for building opencv using g++ was: cmake -D CMAKE_BUILD_TYPE=RelWithDebInfo -D CMAKE_INSTALL_PREFIX=... -D OPENCV_EXTRA

Cannot locate debugging symbols and a lot of idle CPU usage
问题 I'm new to VTune Amplifier and I'm trying to profile OpenCV with a very basic application. Following this guide on recommended compiler options, I compiled OpenCV via CMake with CMAKE_BUILD_TYPE=RelWithDebInfo and -DWITH_OPENMP=ON so both -O2 and -g options are included and OpenMP enabled. My testing OpenCV application is compiled with g++ -I/home/luca/Dropbox/SURFSPM/opencvInstall/include -O3 -g -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.o" -o "main.o" "../main.cpp" via
