Detailed Description

MPI communicator wrapper class.

This header provides the communicator class, which wraps MPI_Comm for safe, RAII-style MPI communicator management.

The communicator class:

• Wraps MPI_Comm in a std::shared_ptr for automatic cleanup
• Provides rank() and size() convenience methods
• Supports implicit conversion to MPI_Comm for use with MPI functions

#include <openpfc/mpi/communicator.hpp>
 
pfc::mpi::communicator comm;
int rank = comm.rank();
int size = comm.size();
MPI_Barrier(comm);  // Implicit conversion
