Detailed Description

template<typename LocalVector_, typename Mirror_>
class FEAT::Global::Muxer< LocalVector_, Mirror_ >

Global multiplexer/demultiplexer implementation.

This class provides the functionality for the transfer of primal and dual vectors between different (nested) partitionings in the domain decomposition approach, including the N:1 joining and 1:N splitting of vectors from a partitioned mesh to the unpartitioned mesh, which is provided by the Global::Splitter class, which uses the Global::Muxer to outsource the actual dirty work. This class is effectively only required by an application directly when using a multigrid hierarchy in combination with recursive partitioning.

Just like Gate class, each Muxer object is bound to a single space-vector pair, so if you require muxer functionality for different vector types, you have to create a different Muxer for each space-vector type pair. You can also utilize the convert() functions to create a new Muxer object from an existing one, assuming that the space object is the same.

Template Parameters

LocalVector_	The local vector type that the muxer is to be applied onto.
Mirror_	The mirror type that is to be used.

To set up an object of this class, one requires various information from the underlying partitioning, especially regarding the parent-child and sibling relations between the processes that are joined/split when transitioning between two partitionings. Basically, the following steps have to be performed:

On each process, call the set_parent() function and provide the sibling communicator, which groups all processes which are to be joined into one parent process, as well as the rank of the remaining parent process with respect to the sibling communicator as well as the identity mirror for all DOFs.
On the parent process, call the push_child() function and provide the mirror for each corresponding child patch, which can be assembled from the 'patch:' meshparts that are (hopefully) generated by the partitioner.
Compile the muxer by calling the compile() function and supplying it with a temporary local vector.

To perform the actual transition between two partitionings, the functions required to be called differ depending on the whether the calling process is a parent process, i.e. it is an active process in both the child and parent communicators, or whether it is only a simple child process, i.e. is only active in the child communicator. On each parent process, the caller has to call the join() or split() functions, which require both the coarse and fine partitioning input/output vectors. On all other child processes, the caller has to call the join_send() function, which only requires the fine partitioning input vector, or the split_recv() function, which only requires the fine partitioning output vector.
