Detailed Description

This enum holds all MPI tags used in point to point MPI communications inside the deal.II library.

We keep these tags in a central location so that they are unique within the library. Otherwise, communication that receives packages might pick up packets from a different algorithm. This is especially true if MPI_ANY_SOURCE is used.

The list of MPI functions that use an MPI tag is:

• MPI_Send, MPI_Recv, MPI_Sendrecv
• MPI_Isend, MPI_Irecv
• MPI_Probe, MPI_Iprobe
• MPI_Comm_create_group, MPI_Intercomm_create, Utilities::MPI::create_group
