    Tutorial Intel TBB Generic Parallel Algorithms | Threading .

    An Intel TBB parallel_for can be used to implement this same functionality, but with parallelism enabled. In the code snippet below, the for loop is replaced by a call to the function parallel_for, which divides up the iterations in to tasks and provides them to the library's task scheduler for parallel execution. The body of the loop in the code stays the same.
