<ompts:test>
<ompts:testdescription>Test which checks the private clause of the task directive. We create a set of tasks in a single region. We defines a variable named sum which gets declared private for each task. Now each task calcualtes a sum using this private variable. Before each calcualation step we introduce a flush command so that maybe the private variabel gets bad. At the end we check if the calculated sum was right.</ompts:testdescription>
