编译器错误 C3036
“operator”:OpenMP“reduction”子句中的运算符标记无效
未正确指定 reduction 子句。
下面的示例生成 C3036:
// C3036.cpp
// compile with: /openmp
static float a[1000], b[1000], c[1000];
void test1(int first, int last) {
static float dp = 0.0f;
#pragma omp for nowait reduction(.:dp) // C3036
// try the following line instead
// #pragma omp for nowait reduction(+: dp)
for (int i = first ; i <= last ; ++i)
dp += a[i] * b[i];
}
