Detailed Description

The delivery component for HyPerConns. It reads the parameters pvpatchAccumulateType, updateGSynFromPostPerspective, and receiveGpu. Note that the choice of pvpatchAccumulateType affects the result of the convolution. The other parameters do not (except for round-off errors induced by parallelism); they only change how the calculation is performed.

Member Function Documentation

bool PV::BaseObject::getDataStructuresAllocatedFlag ( ) const
inlineinherited

Get-method for mDataStructuresAllocatedFlag, which is false on initialization and then becomes true once setDataStructuresAllocatedFlag() is called.

Definition at line 102 of file BaseObject.hpp.

bool PV::BaseObject::getInitialValuesSetFlag ( ) const
inlineinherited

Get-method for mInitialValuesSetFlag, which is false on initialization and then becomes true once setInitialValuesSetFlag() is called.

Definition at line 108 of file BaseObject.hpp.

bool PV::BaseObject::getInitInfoCommunicatedFlag ( ) const
inlineinherited

Get-method for mInitInfoCommunicatedFlag, which is false on initialization and then becomes true once setInitInfoCommunicatedFlag() is called.

Definition at line 95 of file BaseObject.hpp.

void PV::HyPerDeliveryFacade::ioParam_accumulateType ( enum ParamsIOFlag  ioFlag)
protectedvirtual

pvpatchAccumulateType: Specifies the method to accumulate synaptic input

Possible choices are

  • convolve: Accumulates through convolution
  • stochastic: Accumulates through stochastic release

Defaults to convolve.

Definition at line 41 of file HyPerDeliveryFacade.cpp.

void PV::BaseDelivery::ioParam_channelCode ( enum ParamsIOFlag  ioFlag)
protectedvirtualinherited

channelCode: Specifies which channel in the post layer this connection is attached to

Channels can be -1 for no update, or >= 0 for channel number.
0 is excitatory, 1 is inhibitory

Definition at line 29 of file BaseDelivery.cpp.

void PV::HyPerDeliveryFacade::ioParam_updateGSynFromPostPerspective ( enum ParamsIOFlag  ioFlag)
protectedvirtual

updateGSynFromPostPerspective: Specifies if the connection should push from pre or pull from post.

: If set to true, the connection loops over postsynaptic neurons, and each post-neuron pulls from its receptive field. This avoids issues of collisions when parallelizing, but is not able to take advantage of a sparse pre-layer.

If false, the connection loops over presynaptic neurons, and each pre-neuron pushes to its region of influence. This allows efficiency for sparse pre-layers, but requires extra memory to manage potential collisions as multiple pre-neurons write to the same post-neuron.

Definition at line 77 of file HyPerDeliveryFacade.cpp.

void PV::BaseObject::ioParams ( enum ParamsIOFlag  ioFlag,
bool  printHeader,
bool  printFooter 
)
inherited

Method for reading or writing the params from group in the parent HyPerCol's parameters. The group from params is selected using the name of the connection.

If ioFlag is set to write, the printHeader and printFooter flags control whether a header and footer for the parameter group is produces. These flags are set to true for layers, connections, and probes; and set to false for weight initializers and normalizers. If ioFlag is set to read, the printHeader and printFooter flags are ignored.

Note that ioParams is not virtual. To add parameters in a derived class, override ioParamFillGroup.

Definition at line 74 of file BaseObject.cpp.

int PV::HyPerDeliveryFacade::ioParamsFillGroup ( enum ParamsIOFlag  ioFlag)
overrideprotectedvirtual

The virtual method for reading parameters from the parent HyPerCol's parameters, and writing to the output params file.

Derived classes with additional parameters typically override ioParamsFillGroup to call the base class's ioParamsFillGroup method and then call ioParam_[parametername] for each of their parameters. The ioParam_[parametername] methods should call the parent HyPerCol's ioParamValue() and related methods, to ensure that all parameters that get read also get written to the outputParams-generated file.

Reimplemented from PV::BaseDelivery.

Definition at line 28 of file HyPerDeliveryFacade.cpp.

bool PV::HyPerDeliveryFacade::isAllInputReady ( )
overridevirtual

A virtual method to indicate whether the presynaptic layer's input is ready to be delivered.

Reimplemented from PV::BaseDelivery.

Definition at line 196 of file HyPerDeliveryFacade.cpp.

bool PV::BaseObject::isUsingGPU ( ) const
inlineinherited

Returns true if the object requires the GPU; false otherwise. HyPerCol will not initialize the GPU unless one of the objects in its hierarchy returns true

Definition at line 116 of file BaseObject.hpp.

char const * PV::BaseObject::lookupKeyword ( ) const
inherited

Look up the keyword of the params group with the same name as the object.

Definition at line 42 of file BaseObject.cpp.

void PV::BaseObject::readParams ( )
inlineinherited

A method that reads the parameters for the group whose name matches the name of the object. It, along with writeParams(), is a wrapper around ioParams, so that readParams and writeParams automatically run through the same parameters in the same order.

Definition at line 62 of file BaseObject.hpp.

void PV::BaseObject::setDataStructuresAllocatedFlag ( )
inlineprotectedinherited

This method sets mDataStructuresAllocatedFlag to true.

Definition at line 175 of file BaseObject.hpp.

void PV::BaseObject::setInitialValuesSetFlag ( )
inlineprotectedinherited

This method sets the flag returned by getInitialValuesSetFlag to true.

Definition at line 180 of file BaseObject.hpp.

void PV::BaseObject::setInitInfoCommunicatedFlag ( )
inlineprotectedinherited

This method sets mInitInfoCommunicatedFlag to true.

Definition at line 170 of file BaseObject.hpp.

void PV::BaseObject::writeParams ( )
inlineinherited

A method that writes the parameters for the group whose name matches the name of the object. It, along with readParams(), is a wrapper around ioParams, so that readParams and writeParams automatically run through the same parameters in the same order.
