This chapter describes compiler and runtime options affecting programs that utilize the OpenMP API.
Note - To run a parallelized program in a multithreaded environment, you must set the number of threads in the program greater than one. Do this by setting the OMP_NUM_THREADS environment variable prior to running the program to a value greater than one, or from the running program in a call to omp_set_num_threads() function, or by using the num_threads clause on a PARALLEL directive.
