#include #include int main() { int num_threads = 4; omp_set_num_threads(num_threads); int rank; #pragma omp parallel { rank = omp_get_thread_num(); int nr_threads = omp_get_num_threads(); printf("I am thread %i of %i threads ", rank, nr_threads); } } Note the usage of the construct and runtime functions What is the expected output? What are the values of rank and nr_threads? Is the output always the same? What order are the threads printing in? What would happen if we changed the number of threads to 12?
