C++ Tutorial => OpenMP: Parallel For Loop

Example

This example shows how to divide a loop into equal parts and execute them in parallel.

//    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
...

*Please take extra care to not modify the size of the vector used in parallel for loops as allocated range indices doesn't update automatically.
