FLUSH Directive

!$OMP FLUSH(list) 

The FLUSH directive identifies synchronization points at which the implementation is required to provide a consistent view of memory. The directive must appear at the precise point in the code at which the synchronization is required. The optional list argument consists of a comma-separated list of variables that need to be flushed in order to avoid flushing all variables.

The FLUSH directive is implied for the following directives:

• BARRIER
• CRITICAL and END CRITICAL
• END DO
• END PARALLEL
• END SECTIONS
• END SINGLE
• ORDERED and END ORDERED

The directive is not implied if NOWAIT is present.
