parallel threading by ifort on hpc

Dear Freelancer, I am a researcher in the field of materials science and engineering. I have written a FORTRAN code in f.90 and now I am going to apply it on the ifort compiler installed on our university hpc. Unfortunately, when I apply my code on the ifort, the ifort can only compile this code on one node which is not interesting. in fact, I want to compile this code on all existing nodes. Please let me know you can fix my problem or not by any modification of my code or not. Yours Sincerely, Bahman
