Detailed Description

Multi processor extensions to Network. Normally there is only one Network object. In a MP environment we split a complete NN into several Network objects which run in different threads or even different boxes to take advantage of multiple CPUs.

Constructor & Destructor Documentation

MpNetwork::MpNetwork (  Instance *    inst )

Parameters: inst  the Amygdala instance this MpNetwork object will be assiciated to

Member Function Documentation

bool MpNetwork::ConnectNeurons (  Instance *    presynInst, AmIdInt    presynNId, AmIdInt    postsynNId, float    weight, AmTimeInt    delay )

create a synapse between neurons of two different Amygdala instances Parameters: presynInst  a remote instance ID presynNId  a remote neuron ID which is valid in the presynInst postsynNId  a neuron ID valid in this MpNetwork instance weight  the weight of the synapse

vector< Synapse *>* MpNetwork::GetAxon (  unsigned int    instId, unsigned int    nId )

Returns: the axon vector of the neuron nId of the remote instance instId Parameters: instId  the remote instance ID nId  the remote nId

Instance* MpNetwork::GetInstance (    )

Returns: a reference to the associated instance

void MpNetwork::IncrementSimTime (    )  [protected, virtual]

Increment the simTime variable to the next time step. In multithreaded mode, simTime is not incremented until all Nodes have called IncrementSimTime(). Reimplemented from Network.

Member Data Documentation

hash_map<unsigned int, hash_map<unsigned int, vector< Synapse* > *> *> MpNetwork::axonMap [protected]

remote_instId->remoteNid->axon(virtual presyn nId, postSyn Neuron Pointer) each vector represents an axon. The pair holds a virtual nId which is used to access the dendrite of the postsynaptic neuron.

Instance* MpNetwork::instance [protected]

the associated instance
