+* DESCRIPTION:
+* OpenMP Example - Sections Work-sharing - C/C++ Version
+* In this example, the OpenMP SECTION directive is used to assign
+* different array operations to threads that execute a SECTION. Each
+* thread receives its own copy of the result array to work with.
+* AUTHOR: Blaise Barney 5/99
