4 \section para-over Base elements
6 Several classes and methods are available in the MED library to ease the exchange of information
8 For historical reasons, they are all in the same namespace as the non-parallel MEDCoupling functionalities,
11 The core elements of the API are:
12 - \ref ParaFIELD-det "ParaFIELD", the parallel instanciation of a MEDCoupling field
13 - \ref CommInterface-det "CommInterface", communication interface to the gateway to the MPI library
14 - \ref MPIProcessorGroup-det "MPIProcessorGroup", a group of processor in a parallel computation
16 along with all the DEC explained below.
18 \section para-dec Data Exchange Channel - DEC
20 A Data Exchange Channel allows the transfer of information between two processor groups.
21 There are several variants of DEC depending on what you are aiming at:
23 - \ref DisjointDEC-det "DisjointDEC"
24 - \ref InterpKernelDEC-det "InterpKernelDEC"
25 - \ref NonCoincidentDEC-det "NonCoincidentDEC"
26 - \ref OverlapDEC-det "OverlapDEC"
27 - \ref ExplicitCoincidentDEC-det "ExplicitCoincidentDEC"
28 - \ref StructuredCoincidentDEC-det "StructuredCoincidentDEC"
