Member Function Documentation

advance()

void GPUModel::advance ( )

overridevirtual

Advances network state one simulation step.

Advance everything in the model one time step. In this case, that means calling all of the kernels that do the "micro step" updating (i.e., NOT the stuff associated with growth).

Implements Model.

Definition at line 136 of file GPUModel.cpp.

allocDeviceStruct()

void GPUModel::allocDeviceStruct ( void ** allVerticesDevice, void ** allEdgesDevice )

protected

Allocates and initializes memories on CUDA device.

Parameters

[out]	allVerticesDevice	Memory location of the pointer to the neurons list on device memory.
[out]	allEdgesDevice	Memory location of the pointer to the synapses list on device memory.

Definition at line 33 of file GPUModel.cpp.

calcSummationPoint()

void GPUModel::calcSummationPoint ( )

protectedvirtual

Add psr of all incoming synapses to summation points.

Definition at line 182 of file GPUModel.cpp.

copyCPUtoGPU()

void GPUModel::copyCPUtoGPU ( )

overridevirtual

Copy CPU Synapse data to GPU.

Implements Model.

Definition at line 370 of file GPUModel.cpp.

copyGPUtoCPU()

void GPUModel::copyGPUtoCPU ( )

overridevirtual

Copy GPU Synapse data to CPU.

Implements Model.

Definition at line 363 of file GPUModel.cpp.

copySynapseIndexMapHostToDevice()

void GPUModel::copySynapseIndexMapHostToDevice	(	EdgeIndexMap &	synapseIndexMapHost,
		int	numVertices )

Copy EdgeIndexMap in host memory to EdgeIndexMap in device memory.

Parameters

synapseIndexMapHost

Reference to the EdgeIndexMap in host memory.

Definition at line 266 of file GPUModel.cpp.

deleteDeviceStruct()

void GPUModel::deleteDeviceStruct ( void ** allVerticesDevice, void ** allEdgesDevice )

protectedvirtual

Copies device memories to host memories and deallocates them.

Parameters

[out]	allVerticesDevice	Memory location of the pointer to the neurons list on device memory.
[out]	allEdgesDevice	Memory location of the pointer to the synapses list on device memory.

Definition at line 59 of file GPUModel.cpp.

finish()

void GPUModel::finish ( )

overridevirtual

Performs any finalization tasks on network following a simulation.

Implements Model.

Definition at line 121 of file GPUModel.cpp.

printGPUSynapsesPropsModel()

void GPUModel::printGPUSynapsesPropsModel

(

)

const

Print out SynapseProps on the GPU.

Definition at line 377 of file GPUModel.cpp.

setupSim()

void GPUModel::setupSim ( )

overridevirtual

Set up model state, if anym for a specific simulation run.

Sets up the Simulation.

Reimplemented from Model.

Definition at line 77 of file GPUModel.cpp.

updateConnections()

void GPUModel::updateConnections ( )

overridevirtual

Update the connection of all the Neurons and Synapses of the simulation.

Modifies connections between neurons based on current state of the network and behavior over the past epoch. Should be called once every epoch.

Implements Model.
