Detailed Description

template<typename Thing, typename Index = int>
class gridpack::parallel::Shuffler< Thing, Index >

A functor to redistribute things in vectors on multiple processes.

Each process starts with a (possibly empty) vector of things and a vector of equal size that containing a destination process for each thing. After execution, each process will contain a vector of the things assigned to it.

This uses blocking send/receive.

The things redistributed must be copy constructable and serializable.
