Detailed Description

template<class Scalar>
class Thyra::DefaultClusteredSpmdProductVectorSpace< Scalar >

Concrete subclass of VectorSpaceBase that takes a collection of individual VectorSpaceBase objects distributed over many different processes and creates a single vector space.

What this class does is to take different vector space objects distributed over a set of different clusters of processes and then creates a single vector space object.

Let numClusters be the number of clusters that the processes in the global communicator are partitioned into. Each cluster of processes is represented by another communicator known in this process as intraClusterComm. The communicator that links the root of each cluster is called interClusterComm. All communication is performed with just these two communicators. There is no overall global communicator that encompasses all of the processes.

Within a cluster of processes, the number of constituent vector space objects must be the same. Let v[0]..v[numBlocks-1] be the numBlocks VectorBase objects for constituent vectors in this cluster of processes. There is no assumption make whatsoever about the natrue of the VectorSpaceBase objects or the [Multi]VectorBase objects that they create.

ToDo: Finish documentation!

The default copy constructor and assign operator are allowed and they work correctly and perform shallow copies of the constituent vector spaces!

Parameters
intraClusterComm[in] The communicator over just this cluster.
clusterRootRank[in] The rank of the root process in *interClusterComm for this cluster of processes. This is also the process that in included in *interClusterComm (which has a different rank ther obviously).
interClusterComm[in] Defines the communicator between the root processes of all of the clusters. For the root process of each cluster *interClusterComm!=Spmd_COMM_NULL, otherwise interClusterComm==Teuchos::null or *interClusterComm==Spmd_COMM_NULL.
numBlocks[in] Number of vector space blocks for this cluster of processes.
vecSpaces[in] Array (length numBlocks) of the vector spaces for this cluster of processes.
