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. WebOpenMP is an Application Program Interface (API) that may be used to explicitly direct multi-threaded, shared memory parallelism in C/C++ programs. 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.
