The ParaMEDMEM library is based on several classes that describe the coupling between two MPI-based parallel codes.
The classes that make up the API of the library are :
Given two groups of processors groupA (source) and groupB (target), the following code excerpt gives a typical use of the InterpKernelDEC class.
The generation of the interpolation matrix and the corresponding matrix-vector products are performed either on the source, either on the target side.
