communicator(4rheolef)

💖 NAME 💖

communicator — the MPI communicator for C++, bestie, and it's part of rheolef-7.2 ✨

---

🦋 DESCRIPTION 🦋

okay so picture this: you're in a distributed environment (multiple processes, group-chat but make it computing 💅) — this class is literally just a cute lil wrapper around the usual MPI communicator for C++, exactly the way the boost::mpi library hands it to you. no cap.

and if you're in a sequential environment instead? don't even worry. there's a dummy class provided for compatibility purpose — so your code doesn't have a whole meltdown just because there's only one of you. she's an icon for that honestly 🫶

---

🌸 EXAMPLE 🌸

look at her go, main character energy:

communicator comm;
cout << 'my_proc = ' << comm.rank() << endl
     << 'nb_proc = ' << comm.size() << endl;

that's it. that's the vibe. 👑

---

✨ IMPLEMENTATION ✨

fr fr, this documentation has been generated from file linalg/lib/communicator.h 🎀

struct communicator {
  typedef std::vector<int>::size_type size_type;
  int size() const;
  int rank() const;
};

so tiny, so powerful, the way she does the absolute most with the absolute least 💀💜
