C++ (Cpp) HOOD_NEW::sum Examples

Example #1

File: main.cpp Project: Haider-BA/libgeodecomp

 static void updateLineX(HOOD_NEW& hoodNew, int indexEnd, HOOD_OLD& hoodOld, unsigned /* nanoStep */)
 {
     for (int i = hoodOld.index(); i < indexEnd; ++i, ++hoodOld) {
         ShortVec tmp;
         tmp.load_aligned(&hoodNew->sum() + i * C);
         for (const auto& j: hoodOld.weights(0)) {
             ShortVec weights;
             ShortVec values;
             weights.load_aligned(j.second());
             values.gather(&hoodOld->value(), j.first());
             tmp += values * weights;
         }
         tmp.store_aligned(&hoodNew->sum() + i * C);
     }
 }

             weights.load_aligned(j.second());
             // fixme: is this gahter actually correct? shouldn't we use offset 0 for the gather? see also hpxperformancetests/main.cpp
             values.gather(&hoodOld->value(), j.first());
             tmp += values * weights;
