+/******************************************************************************
+* FILE: omp_workshare1.c
+* DESCRIPTION:
+*   OpenMP Example - Loop Work-sharing - C/C++ Version
+*   In this example, the iterations of a loop are scheduled dynamically
+*   across the team of threads.  A thread will perform CHUNK iterations
+*   at a time before being scheduled for the next CHUNK of work.
