[Mailman] problem with OpenMP

[harry potter]

    I begin to learn about OpenMP. I would like to compare between OpenMP (shared memory ) and MPI (distributed memory). I have used OpenPBS to submit jobs for each processors on multicomputer but I have the problem that when I use " omp_get_num_procs() " to get the number of processors I found only one processor that is invalid because I setup 3 nodes( 1 head node and 2 compute nodes), I should found two processors. Can you introduce me about this problem ? Please help me. thanks so much,harry potter
