It is not intrusive on the original serial code in that the OpenMP instructions are made in pragmas interpreted by the compiler. OpenMP uses the fork-join model of parallel execution.

Web19 de dez. de 2024 · There are 4 threads. The for loop goes from 1 to 1000. Total 1000 iterations. So, thread 0 executes 1 to 250. Thread 1 executes 251 to 500. Thread 2 executes 501 to 750. Thread 3 executes 751 to 1000. So in this way, the time taken would reduce as the work is now not done in sequential order. Rather it is executed parallelly.
