Member Function Documentation

◆ changeLocalIds()

void Arcane::NullVariableSynchronizer::changeLocalIds ( Int32ConstArrayView old_to_new_ids )

inlineoverridevirtual

Called when the local IDs of the entities are modified.

Implements Arcane::IVariableSynchronizer.

Definition at line 57 of file NullVariableSynchronizer.cc.

◆ communicatingRanks()

Int32ConstArrayView Arcane::NullVariableSynchronizer::communicatingRanks ( )

inlineoverridevirtual

Ranks of subdomains with which communication occurs.

Implements Arcane::IVariableSynchronizer.

Definition at line 87 of file NullVariableSynchronizer.cc.

◆ compute()

void Arcane::NullVariableSynchronizer::compute ( )

inlineoverridevirtual

Recalculates the synchronization information.

This operation is collective.

This function must be called if the entities in itemGroup() change owner or if the group itself evolves. TODO: call this function automatically if needed.

Implements Arcane::IVariableSynchronizer.

Definition at line 56 of file NullVariableSynchronizer.cc.

◆ ghostItems()

Int32ConstArrayView Arcane::NullVariableSynchronizer::ghostItems ( Int32 index )

inlineoverridevirtual

List of local IDs of ghost entities with a subdomain.

The rank of the subdomain is that of communicatingRanks()[index].

Implements Arcane::IVariableSynchronizer.

Definition at line 98 of file NullVariableSynchronizer.cc.

◆ itemGroup()

const ItemGroup & Arcane::NullVariableSynchronizer::itemGroup ( )

inlineoverridevirtual

Entity group used for synchronization.

The current implementation only supports the group of all entities of a family.

Implements Arcane::IVariableSynchronizer.

Definition at line 55 of file NullVariableSynchronizer.cc.

◆ onSynchronized()

EventObservable< const VariableSynchronizerEventArgs & > & Arcane::NullVariableSynchronizer::onSynchronized ( )

inlineoverridevirtual

Event sent at the beginning and end of synchronization.

This event is sent during calls to the methods synchronize(IVariable* var) and synchronize(VariableCollection vars). If you wish to be notified of synchronizations for all instances of IVariableSynchronizer, you must use IVariableMng::synchronizerMng().

Implements Arcane::IVariableSynchronizer.

Definition at line 108 of file NullVariableSynchronizer.cc.

◆ parallelMng()

IParallelMng * Arcane::NullVariableSynchronizer::parallelMng ( )

inlineoverridevirtual

Associated parallel manager.

Implements Arcane::IVariableSynchronizer.

Definition at line 50 of file NullVariableSynchronizer.cc.

◆ sharedItems()

Int32ConstArrayView Arcane::NullVariableSynchronizer::sharedItems ( Int32 index )

inlineoverridevirtual

List of local IDs of entities shared with a subdomain.

The rank of the subdomain is that of communicatingRanks()[index].

Implements Arcane::IVariableSynchronizer.

Definition at line 92 of file NullVariableSynchronizer.cc.

◆ synchronize() [1/4]

void Arcane::NullVariableSynchronizer::synchronize ( IVariable * var )

inlineoverridevirtual

Synchronizes the variable var in blocking mode.

Implements Arcane::IVariableSynchronizer.

Definition at line 61 of file NullVariableSynchronizer.cc.

Here is the caller graph for this function:

◆ synchronize() [2/4]

void Arcane::NullVariableSynchronizer::synchronize	(	IVariable *	var,
		Int32ConstArrayView	local_ids )

inlineoverridevirtual

Synchronizes the variable var on the entities local_ids in blocking mode.

Only the entities listed in local_ids will be synchronized. Note: an entity present in this list on one subdomain must be present in this list for any other subdomain that owns this entity.

Reimplemented from Arcane::IVariableSynchronizer.

Here is the call graph for this function:

◆ synchronize() [3/4]

void Arcane::NullVariableSynchronizer::synchronize ( VariableCollection vars )

inlineoverridevirtual

Synchronizes the variables vars in blocking mode.

All variables must belong to the same family and this entity group.

Implements Arcane::IVariableSynchronizer.

Definition at line 74 of file NullVariableSynchronizer.cc.

◆ synchronize() [4/4]

void Arcane::NullVariableSynchronizer::synchronize	(	VariableCollection	vars,
		Int32ConstArrayView	local_ids )

inlineoverridevirtual

Synchronizes the variables vars in blocking mode.

All variables must belong to the same family and this entity group.

Only the entities listed in local_ids will be synchronized. Note: an entity present in this list on one subdomain must be present in this list for any other subdomain that owns this entity.
