SYMMETRIC variables are private data that are guaranteed to be at the same storage location on every processor. The feature is beneficial to implementations that provide one-way communication functionality. One task can either get or put data into another task's symmetric data location, without involving the other task. There is an implicit barrier synchronization after SYMMETRIC data is allocated.
