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 138 of file GPUModel.cpp.

allocDeviceStruct()

void GPUModel::allocDeviceStruct ( )

protected

Allocates and initializes memories on CUDA device.

Definition at line 52 of file GPUModel.cpp.

copyCPUtoGPU()

void GPUModel::copyCPUtoGPU ( )

overridevirtual

Allocate and Copy CPU Synapse data to GPU.

Copies neuron and synapse data from CPU to GPU memory. TODO: Refactor this. Currently, GPUModel handles low-level memory transfer for vertices and edges. Consider moving this responsibility to a more appropriate class, such as a dedicated memory manager or the OperationManager, to better separate concerns and keep the model focused on high-level coordination.

Implements Model.

Definition at line 283 of file GPUModel.cpp.

copyGPUtoCPU()

virtual void GPUModel::copyGPUtoCPU ( )

inlineoverridevirtual

Prints debug information about the current state of the network.

Copy GPU Edge data to CPU.

Implements Model.

Definition at line 95 of file GPUModel.h.

deleteDeviceStruct()

void GPUModel::deleteDeviceStruct ( )

protectedvirtual

Deallocates device memories.

Copies device memories to host memories and deallocates them.

Definition at line 64 of file GPUModel.cpp.

finish()

void GPUModel::finish ( )

overridevirtual

Performs any finalization tasks on network following a simulation.

Implements Model.

Definition at line 122 of file GPUModel.cpp.

getAllEdgesDevice()

AllEdgesDeviceProperties *& GPUModel::getAllEdgesDevice

(

)

Getter for edge (synapse) structures in device memory.

Getter for synapse structures in device memory.

Definition at line 342 of file GPUModel.cpp.

getAllVerticesDevice()

AllVerticesDeviceProperties *& GPUModel::getAllVerticesDevice

(

)

Getter for vertex (neuron) structures in device memory.

Getter for neuron structure in device memory.

Definition at line 336 of file GPUModel.cpp.

printGPUEdgesPropsModel()

void GPUModel::printGPUEdgesPropsModel

(

)

const

Print out EdgeProps on the GPU.

Definition at line 330 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 81 of file GPUModel.cpp.

updateConnections()

void GPUModel::updateConnections ( )

overridevirtual

Update the connection of all the vertices and edges of the simulation.

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

Implements Model.
