orte-info(1)

💖 orte-info — the ORTE tea, served piping hot 💖

Hey bestie 🫶 pull up a chair, because this is the manual page for orte-info, one of the little icons living inside Open MPI. Think of it as the "tell me everything about yourself" button for your ORTE install. No gatekeeping, we're spilling it all ✨

---

✨ NAME ✨

orte-info — literally just: display information about the ORTE installation. That's the whole gig. And it eats. 👑

---

✨ SYNOPSIS ✨

orte-info [options]

Short, sweet, and it takes options like it takes compliments. 💅

---

✨ DESCRIPTION ✨

Okay so orte-info gives you the detailed scoop on your ORTE installation. Not the vague "yeah it's installed somewhere" vibe — the real, receipts-included, fully-detailed tea. It's the main character in at least three common scenarios:

1. Checking your local configuration and seeing exactly how ORTE was installed. 🔍
2. Submitting bug reports / help requests to the ORTE community (see http://www.open-mpi.org/community/help/) — like, they're gonna need the deets, bestie. 🐛
3. Seeing a list of installed ORTE plugins and querying what MCA parameters they support. 🔌

Three jobs, zero notes, we love a versatile queen. 🌸

---

✨ OPTIONS ✨

orte-info accepts the following options. Yes, all of them. We're not skipping any, that's not the vibe. 💖

• -a, --all — Show all configuration options and MCA parameters. Everything. The whole closet, no doors closed. 🚪
• --arch — Show the architecture ORTE was compiled on. Its star sign, basically. 🏗️
• -c, --config — Show configuration options. Just the config ones, if you're being picky. ⚙️
• -gmca, --gmca <param> <value> — Pass global MCA parameters that are applicable to all contexts. Global as in for everyone at the party. 🌍
• -h, --help — Shows help / usage message. When you're lost and need a friend. 🆘
• --hostname — Show the hostname that ORTE was configured and built on. Where was the queen born, exactly? 🏠
• --internal — Show internal MCA parameters (not meant to be modified by users). 👀 Look all you want, bestie, but do not touch. That's for the devs.
• -mca, --mca <param> <value> — Pass context-specific MCA parameters; they are considered global if --gmca is not used and only one context is specified. Situational, but flexible. 🎀
• --param <type> <component> — Show MCA parameters. The first parameter is the type of the component to display; the second parameter is the specific component to display (or the keyword "all", meaning "display all components of this type"). Two args, one very specific request. 💬
• --parsable — When used in conjunction with other parameters, the output is displayed in a machine-parsable format. Robots get to read it too. 🤖
• --parseable — Synonym for --parsable. Same energy, different spelling. ✨
• --path <type> — Show paths that ORTE was configured with. Accepts the following parameters: prefix, bindir, libdir, incdir, pkglibdir, sysconfdir. Pick your path, bestie. 🗺️
• --pretty — When used in conjunction with other parameters, the output is displayed in 'prettyprint' format (default). Aesthetic output, as it should be. 💅
• -v, --version <component> <scope> — Show version of ORTE or a component. <component> can be the keywords "ompi" or "all", the name of a framework (e.g., "coll" shows all components in the coll framework), or the name of a specific component (e.g., "pls:rsh" shows the information from the rsh PLS component). <scope> can be one of: full, major, minor, release, greek, svn. The most customizable option here and it knows it. 👑
• --param <type> <component> — (yes, we already said it, but she's important) — show MCA parameters, where the first parameter is the type of component and the second is the specific component, or the keyword "all" for every component of that type. 🌈

⚠️ Heads up, queen: --internal parameters are not meant to be modified by users. Look, don't touch. That's the rule.
