: This class describes a group of processors on which
a portion of code executes simultaneously. It provides all the methods for exchanging data between the processors of the group (mpsum, send, recv, ...), and for synchronizing processors (barrier). It is specialized according to the network layer (MPI, PVM, ...). Note: these methods are reserved for low-level operations (TRUST kernel). In normal code, use the high-level communication class methods: (envoyer(), envoyer_broadcast(), class Schema_Comm, class Process, etc.) To create a new group and use it, see class PE_Groups. For the initialization procedure, see PE_Groups::Initialize().
