+C FILE: omp_hello.f
+C DESCRIPTION:
+C OpenMP Example - Hello World - Fortran Version
+C In this simple example, the master thread forks a parallel region.
+C All threads in the team obtain their unique thread number and print it.
+C The master thread only prints the total number of threads. Two OpenMP
+C library routines are used to obtain the number of threads and each
+C thread's number.
