🎵 MUSIC(1) — General Commands Manual 🎵

okay bestie, sit down, grab a strawberry 🍓, because we're about to talk about music, and she is iconic.

✨ NAME ✨

music — launch a multi-simulation using MUSIC 💅

🌈 SYNOPSIS 🌈

mpirun [mpirun-options] music [options] config
music [options] config...

two whole forms, two whole vibes, no cap.

💖 DESCRIPTION 💖

so this manual page documents the music utility briefly — like, the cliffnotes version, the trailer, the teaser 🎀.

music is used to launch a multi-simulation, which is lowkey just an MPI job that's been partitioned between a set of parallel programs. yes, plural, multiple programs, all doing their thing at once, main character energy for each of them. 👑

but here's the catch, and it's a big one: those programs need to be MUSIC-aware (go read the documentation for the MUSIC library, iykyk). and MUSIC also provides facilities for these programs to exchange data between each other — like a group chat, but for processes. 🫶

and the second form of the command up there (the one without mpirun)? she's not useless, she's just doing a different job. you can use her to print out an application rank map or version information. slay.

✨ OPTIONS ✨

music follows the usual GNU command line syntax — long options start with two dashes (-). a lil summary of the options is included below, but for the complete description, bestie, you gotta see the MUSIC manual. 📖

  • -h, --help — Show summary of options. the "wait what does this do again" button 🙈
  • -m, --map — Print application rank map. your little map of who's who 🗺️
  • -v, --version — Show version of program. the classic "which one am I even running" moment 💀
