gmx::CommSetup Struct Reference

Collaboration diagram for gmx::CommSetup:

Description

The communication setup for the domain decomposition, both PP and PME.

Public Attributes
MpiComm	commMySim = MpiComm(MpiComm::SingleRank{})
	MPI communicator for the whole simulation.
MpiComm	commMyGroup = MpiComm(MpiComm::SingleRank{})
	MPI communicator for our PP and/or PME ranks.
CartesianRankSetup	cartSetup
	Contains a valid Cartesian-communicator-based setup, or defaults.
bool	hasPPDuty
	Whether this rank computes particle-particle interactions.
bool	hasPmeDuty
	Whether this rank computes particle-particle interactions.
ivec	ddCellIndex = { 0, 0, 0 }
	Number of DD cells in each dimension.
std::vector< int >	pmeRanks
	When interleaving PP and PME ranks, the IDs within commMySim of PME-only ranks.
