Set number of threads using omp_set_num_threads() to 2, but omp_get_num_threads() returns 1

Question

I have the following C/C++ code using OpenMP:

    int nProcessors=omp_get_max_threads();
    if(argv[4]!=NULL){
        printf(\"argv[4]: %s\\n\",argv[4]);
              


        

Answer 1

you are using the wrong function. use omp_get_max_threads to check for the maximum number of allowed threads.
