Constructor & Destructor Documentation

Create MD graph object.

Parameters

[in]	deviceStreamManager	Device stream manager object
[in]	simulationWork	Simulation workload structure
[in]	mpiComm	MPI communicator for PP domain decomposition
[in]	evenOrOddStep	Whether this graph corresponds to even or odd step
[in]	wcycle	Wall cycle timer object

bool gmx::MdGpuGraph::Impl::captureThisStep ( bool canUseGraphThisStep )

Decide whether graph will be captured this step.

Parameters

[in] canUseGraphThisStep Whether graph can be used this step

void gmx::MdGpuGraph::Impl::createExecutableGraph ( bool forceGraphReinstantiation )

Create executable graph from recorded graph.

Parameters

[in] forceGraphReinstantiation Whether graph reinstantiation should be used instead of graph exec update

void gmx::MdGpuGraph::Impl::disableForDomainIfAnyPpRankHasCpuForces ( bool disableGraphAcrossAllPpRanks )

Disable graph across all PP ranks for this domain, due to presence of CPU forces on any PP rank.

Parameters

[in] disableGraphAcrossAllPpRanks Whether graph usage should be disabled across all PP ranks

GpuEventSynchronizer* gmx::MdGpuGraph::Impl::getPpTaskCompletionEvent ( )

Getter for task completion event for this graph.

void gmx::MdGpuGraph::Impl::launchGraphMdStep ( GpuEventSynchronizer * xUpdatedOnDeviceEvent )

Launch graph corresponding to MD step.

   \param [inout] xUpdatedOnDeviceEvent  Event marked when coordinates have been updated o\

n device

void gmx::MdGpuGraph::Impl::setUsedGraphLastStep ( bool usedGraphLastStep )

Set whether graph was used in the previous step.

Parameters

[in] usedGraphLastStep Whether graph was used in the last step

void gmx::MdGpuGraph::Impl::startRecord ( GpuEventSynchronizer * xReadyOnDeviceEvent )

Denote start of graph region, starts graph recording, and forks those streams involved in graph.

Parameters

[in] xReadyOnDeviceEvent Event marked when coordinates are ready on device
