gmx::MDModulesNotifiers Struct Reference

#include <gromacs/utility/mdmodulesnotifiers.h>


Group of notifers to organize that MDModules can receive callbacks they subscribe to.

MDModules use members of this struct to subscribe to notifications of particular events. When the event occurs, the callback provided by a particular MDModule will be passed a parameter of the particular type they are interested in.

Typically, during the setup phase, modules subscribe to notifiers that interest them by passing callbacks that expect a single parameter that describes the event. These are stored for later use. See the sequence diagram that follows:


When the event occurs later on, the stored callbacks are used to allow the modules to react. See the following sequence diagram, which assumes that exampleNotifier was configured as in the previous sequence diagram.


The template arguments to the members of this struct are the parameters passed to the callback functions, one type per callback. Arguments passed as pointers are always meant to be modified, but never meant to be stored (in line with the policy everywhere else).

BuildMDModulesNotifier<MDModulesCheckpointReadingDataOnMaster, MDModulesCheckpointReadingBroadcast, MDModulesWriteCheckpointData>::type gmx::MDModulesNotifiers::checkpointingNotifier_

Handles subscribing and calling checkpointing callback functions.

MDModulesCheckpointReadingDataOnMaster provides modules with their checkpointed data on the master node and checkpoint file version MDModulesCheckpointReadingBroadcast provides modules with a communicator and the checkpoint file version to distribute their data MDModulesWriteCheckpointData provides the modules with a key-value-tree builder to store their checkpoint data and the checkpoint file version

Handles subscribing and calling callbacks during simulation setup.

const KeyValueTreeObject& provides modules with the internal data they wrote to .tpr files LocalAtomSetManager* enables modules to add atom indices to local atom sets to be managed const MDLogger& Allows MdModule to use standard logging class for messages output const gmx_mtop_t& provides the topology of the system to the modules MDModulesEnergyOutputToDensityFittingRequestChecker* enables modules to report if they want to write their energy output to the density fitting field in the energy files MDModulesEnergyOutputToQMMMRequestChecker* enables QMMM module to report if it want to write their energy output to the "Quantum En." field in the energy files SeparatePmeRanksPermitted* enables modules to report if they want to disable dedicated PME ranks const PbcType& provides modules with the periodic boundary condition type that is used during the simulation const SimulationTimeStep& provides modules with the simulation time-step that allows them to interconvert between step time information const t_commrec& provides a communicator to the modules during simulation setup const MdRunInputFilename& Allows modules to know .tpr filename during mdrun
