Detailed Description

template<typename Set>
class stapl::sgl::sparse_frontier< Set >

Set of active vertices during a traversal.

Template Parameters

Set	The GID set type that will store the active vertices' GIDs

Member Function Documentation

__attribute__()

template<typename Set >

stapl::sgl::sparse_frontier< Set >::__attribute__

(

(always_inline)

)

const &

Mark a vertex as active in the next superstep.

Parameters

The	GID of the vertex to add

get_location_md()

runtime::location_md& stapl::p_object::get_location_md ( void  )

noexceptinherited

Returns the location metadata of the location this object registered in. noexcept

noexcept

advance_epoch()

void stapl::p_object::advance_epoch ( void  )

inherited

Advances the epoch of the object.

Advancing the epoch will flush any pending RMIs. It will also increase the epoch of the current gang if the object is not a named object.

unlock()

void stapl::p_object::unlock ( void  )

inherited

Used by lock_guard functionality in method of derived classes to request atomicity with respect to incoming RMIs.

Mutates counter in the associated runqueue.

lock()

void stapl::p_object::lock ( void  )

inherited

Used by lock_guard functionality in method of derived classes to request atomicity with respect to incoming RMIs.

Mutates counter in the associated runqueue.

try_lock()

bool stapl::p_object::try_lock ( void  )

inherited

Attempt to maintain atomicity with respect to incoming RMIs.

Mutates counter in the associated runqueue.

Returns

true if the lock was able to be acquired. false if it is already locked.
