Detailed Description

Object to broadcast a graph in CSR format used by METIS.

Constructor & Destructor Documentation

rmi_allgather_obj()

stapl::partitioner_details::rmi_allgather_obj::rmi_allgather_obj	(	metis_graph const &	local_graph,
		metis_graph &	global_graph
	)

Parameters

local_graph	local piece of the graph.
global	graph graph storing the result of the broadcast.

Assuming global graph is already allocated with the required memory to hold all concatenations of the local graphs.

Member Function Documentation

append_metis_graph()

void stapl::partitioner_details::rmi_allgather_obj::append_metis_graph

(

metis_graph const &

g

)

Append a piece of graph to the broadcast result m_global_graph.

Parameters

g	piece of graph in CSR format used by METIS.

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.
