🦋 SYNOPSIS 🦋

starpu_mpi_comm_matrix.py <output_execution>

---

🌸 DESCRIPTION 🌸

Okay so picture this: it's an offline tool 👑 — meaning it doesn't run while your app is running, it comes after, like the friend who shows up with the photo dump once the party's over — and what it does is draw a communication matrix. That's it, that's the whole job, and it ate. 💅

You hand it your <output_execution> and it turns the MPI chatter into a matrix you can actually look at. No cap.

🎀 OPTIONS 🎀

• -h, --help — shows you this help and then dips, that's the whole thing 🫶
• -v, --version — spits out the version info and exits, iconic behaviour ⭐
• -png — produce plots in png format instead (default is pdf, iykyk) 🖼️✨

🚨 not me reminding you: those are exactly -h, -v and -png — single dash on the last one, don't you dare add a second one, fr fr 💀
