gmx::LocalTopologyChecker Class Reference

#include <gromacs/domdec/localtopologychecker.h>


Has responsibility for checking that the local topology distributed across domains describes a total number of bonded interactions that matches the system topology.

This uses the ObservablesReducer framework to check that the count of bonded interactions in the local topology made for each domain sums to the expected value. Because this check is not urgent, the communication that it requires is done at the next opportunity, rather than requiring extra communication. If the check fails, a fatal error stops execution. In principle, if there was a bug, GROMACS might crash in the meantime because of the wrong forces. However as a bug is unlikely we optimize by avoiding creating extra overhead from communication.

void scheduleCheckOfLocalTopology (int numBondedInteractionsToReduce)
 Set that the local topology should be checked via observables reduction whenever that reduction is required by another module. In case of a single domain a direct assertion is performed instead.
