Detailed Description

Runqueue shared among locations of a gang that are on the same process.

std::unique_lock< std::mutex > stapl::runtime::shared_runqueue::acquire ( gang_md & g )

Acquires the runqueue associated with g.

Warning: This is a potential contention point as the lock in the deferred requests queue can only be held by one thread at a time.

Returns: An acquired lock that protects the queue of deferred requests and should only be released when gang metadata g is registered.
