Detailed Description

Implementation of a WiringMethod which allows fast wiring of populations which span multiple MPI nodes.

The basic idea here is that on two MPI nodes A and B only possible connections (a,b) between SimObjects a on A and b on B are considered and not the whole populations. Hence a lot of time is saved by not considering connectins (x,y) where either x not on A or y not on B. This allows basically for a wiring time which is proportional to n*n where n is the numbers of SimObjects belonging to one MPI node instead of N x N where N is the number of SimObject's in the whole population.

Member Function Documentation

unsigned DistributedSyncWiringMethod::connect ( const SimObjectPopulation &  source,
const SimObjectPopulation &  destination,
ConnectionIterator &  iterator,
bool  collectPairs = false,
WiringMethod::ConnectPairsVector  connectPairs = WiringMethod::ConnectPairsVector(new vector< pair< SimObject::ID, SimObject::ID > >) 
) [virtual]

Make direct connections between source and dest. population.

Parameters:
source The source population
destination The destination population (can be the same as source population)
iterator The connection iterator to use (e.g. PredicateBasedConnections or RandomConnections ) which determines which connections are made.
collectPairs Flaf which idicates wheter the pairs of ID's of the connected objects souble be collected or not.
connectPairs Vector where the collected connection pairs are written to if collectPairs == true Be aware that the collected pairs are collected on each node of a distributed simulation when using a DistributedSingleThreadNetwork or DistributedMultiThreadNetwork which may lead to a large memory consumption.

WiringMethod::ConnectPairsVector  connectPairs = WiringMethod::ConnectPairsVector(new vector< pair< SimObject::ID, SimObject::ID > >) 
) [virtual]

Make connections between source and dest. population using a SimObjectFactory (usually some synapse) to connect the objects.

Parameters:
source The source population
destination The destination population (can be the same as source population)
connector The SimObjectFactory to use to generate connecting objects (e.g. StaticSpikingSynapse)
iterator The connection iterator to use (e.g. PredicateBasedConnections or RandomConnections ) which determines which connections are made.
collectIDs Flag which idicates whether the SimObject::ID's of the generated connector objects should be collected or not.
collectPairs Flaf which idicates wheter the pairs of ID's of the connected objects souble be collected or not.
connectPairs Vector where the collected connection pairs are written to if collectPairs == true Be aware that the collected ID's or indices are collected on each node of a distributed simulation when using a DistributedSingleThreadNetwork or DistributedMultiThreadNetwork which may lead to a large memory consumption.
