// .NAME vtkMPIMToNSocketConnection - class to create socket connections between two servers
//
// .SECTION Description vtkMPIMToNSocketConnection is a
// class used to create socket connections between the render and data
// servers. This used for example when data is on a super computer (SGI,
// IBM, etc) and Rendering on a Linux cluster with hardware graphics support.
// This problem is known as the "M" to "N" geometry load redistribution
// problem. It addresses the common case where there is a significante
// mismatch in the size of large parallel computing resources and the often
// smaller parallel hardward-accelerated rendering resources. The larger
// number of processors on the compute servers are called M, and the smaller
// number of rendering processors are call N. This class is used to create N
// vtkSocketCommunicator's that connect the first N of the M processes on the
// data server to the N processes on the render server.
