ExclusionChecker::Impl Class Reference

Collaboration diagram for ExclusionChecker::Impl:

Description

Data to help check local topology construction.

Partitioning could incorrectly miss a bonded interaction. However, checking for that requires a global communication stage, which does not otherwise happen during partitioning. So, for performance, we do that alongside the first global energy reduction after a new DD is made. These variables handle whether the check happens, its input for this domain, output across all domains, and the expected value it should match.

Public Member Functions
	Impl (const gmx::MpiComm &MpiComm, const gmx_mtop_t &mtop)
	Constructor.
void	check (int numTotalPerturbedExclusionsFound)
	Checks the count passed with the expected number and exits with a fatal error at mismatch.

Public Attributes
const gmx::MpiComm &	mpiComm_
	Object used when reporting that exclusions are missing { Communication object for my group.
gmx::ArrayRef< double >	reductionBuffer_
	} More...
gmx::ObservablesReducerBuilder::CallbackToRequireReduction	callbackToRequireReduction_
	Callback used after repartitioning to require reduction of numBondedInteractionsToReduce so that the total number of bonded interactions can be checked.
int	expectedNumGlobalPerturbedExclusions_
	The expected number of global non-bonded perturbed pair exclusions.

}

View used for computing the global number of bonded interactions.

Can be written any time, but that is only useful when followed by a call of the callbackToRequireReduction. Useful to read only from the callback that the ObservablesReducer will later make after reduction.
