Detailed Description

Function Documentation

genDefinitions()

void genDefinitions	(	const NNmodel &	model,
		const string &	path,
		int	localHostID
	)

A function that generates predominantly host-side code.

In this function host-side functions and other code are generated, including: Global host variables, "allocatedMem()" function for allocating memories, "freeMem" function for freeing the allocated memories, "initialize" for initializing host variables, "gFunc" and "initGRaw()" for use with plastic synapses if such synapses exist in the model.

Parameters

model	Model description
path	Path for code generationn
localHostID	Host ID of local machine

genMakefile()

void genMakefile	(	const NNmodel &	model,
		const string &	path
	)

A function that generates the Makefile for all generated GeNN code.

Path for code generation

Parameters

model	Model description
path	Path for code generation

genMSBuild()

void genMSBuild	(	const NNmodel &	model,
		const string &	path
	)

A function that generates an MSBuild script for all generated GeNN code.

Path for code generation

Parameters

model	Model description
path	Path for code generation

genRunner()

void genRunner	(	const NNmodel &	model,
		const string &	path,
		int	localHostID
	)

ID of local host.

Method for cleaning up and resetting device while quitting GeNN

Parameters

model	Model description
path	Path for code generationn
localHostID	ID of local host

genRunnerGPU()

void genRunnerGPU	(	const NNmodel &	model,
		const string &	path,
		int	localHostID
	)

A function to generate the code that simulates the model on the GPU.

The function generates functions that will spawn kernel grids onto the GPU (but not the actual kernel code which is generated in "genNeuronKernel()" and "genSynpaseKernel()"). Generated functions include "copyGToDevice()", "copyGFromDevice()", "copyStateToDevice()", "copyStateFromDevice()", "copySpikesFromDevice()", "copySpikeNFromDevice()" and "stepTimeGPU()". The last mentioned function is the function that will initialize the execution on the GPU in the generated simulation engine. All other generated functions are "convenience functions" to handle data transfer from and to the GPU.

Parameters

model	Model description
path	Path for code generation
localHostID	ID of local host

genSupportCode()

void genSupportCode	(	const NNmodel &	model,
		const string &	path
	)

Path for code generationn.

Parameters

model	Model description
path	Path for code generationn
