gmx::LocalTopologyChecker::Impl Class Reference
+ Collaboration diagram for gmx::LocalTopologyChecker::Impl:


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.

gmx::ArrayRef<double> gmx::LocalTopologyChecker::Impl::reductionBuffer_


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.
