OpenMP Parallel For Loop

此示例顯示如何將迴圈劃分為相等的部分並並行執行它們。

//    Splits element vector into element.size() / Thread Qty
//    and allocate that range for each thread.
#pragma omp parallel for
for    (size_t i = 0; i < element.size(); ++i)
    element[i] = ...

//    Example Allocation (100 element per thread)
//    Thread 1 : 0 ~ 99
//    Thread 2 : 100 ~ 199
//    Thread 2 : 200 ~ 299
//    ...

//    Continue process
//    Only when all threads completed their allocated
//    loop job
...

*請特別注意不要修改並行 for 迴圈使用的向量的大小,因為分配的範圍索引不會自動更新
