Detailed Description

MPI utilities and wrappers.

This header provides convenient MPI utility functions and aggregates all MPI-related components (communicator, environment, timer, worker).

The namespace pfc::mpi contains:

• get_rank(): Get current MPI rank
• get_size(): Get total number of MPI processes
• Communicator: MPI communicator wrapper
• Environment: MPI initialization/finalization management
• Timer: MPI timing utilities
• Worker: MPI task distribution helpers

#include <openpfc/mpi.hpp>
 
int main(int argc, char** argv) {
    pfc::mpi::Environment env(argc, argv);
    int rank = pfc::mpi::get_rank();
    int size = pfc::mpi::get_size();
    std::cout << "Rank " << rank << " of " << size << std::endl;
    return 0;
}
