Detailed Description

Information on the computing core allocation topology.

An instance of this class is linked to an IParallelMng.

It allows knowing how the ranks of this IParallelMng are allocated on the cluster and within the processes.

Member Function Documentation

isMasterMachine()

virtual bool Arcane::IParallelTopology::isMasterMachine ( ) const

pure virtual

Indicates if this rank is the master rank for a machine (node).

Implemented in Arcane::ParallelTopology.

isMasterProcess()

virtual bool Arcane::IParallelTopology::isMasterProcess ( ) const

pure virtual

Indicates if this rank is the master within the ranks of this process.

Implemented in Arcane::ParallelTopology.

machineRank()

virtual Int32 Arcane::IParallelTopology::machineRank ( ) const

pure virtual

Rank of this instance in the list of machines (nodes).

This rank is between 0 and masterMachineRanks().size().

Implemented in Arcane::ParallelTopology.

machineRanks()

virtual Int32ConstArrayView Arcane::IParallelTopology::machineRanks ( ) const

pure virtual

List of ranks that are on the same machine.

Implemented in Arcane::ParallelTopology.

masterMachineRanks()

virtual Int32ConstArrayView Arcane::IParallelTopology::masterMachineRanks ( ) const

pure virtual

List of master ranks for each machine (node).

This list is the same for all ranks.

Implemented in Arcane::ParallelTopology.

masterProcessRanks()

virtual Int32ConstArrayView Arcane::IParallelTopology::masterProcessRanks ( ) const

pure virtual

List of master ranks for each process.

This list is the same for all ranks.

Implemented in Arcane::ParallelTopology.

parallelMng()

virtual IParallelMng * Arcane::IParallelTopology::parallelMng ( ) const

pure virtual

Associated parallelism manager.

Implemented in Arcane::ParallelTopology.

processRank()

virtual Int32 Arcane::IParallelTopology::processRank ( ) const

pure virtual

Rank of this instance in the list of processes.

This rank is between 0 and masterProcessRanks().size().

Implemented in Arcane::ParallelTopology.

processRanks()

virtual Int32ConstArrayView Arcane::IParallelTopology::processRanks ( ) const

pure virtual

List of ranks that are in the same process (in multi-threading).

Implemented in Arcane::ParallelTopology.
