oar_resources_init(1)

💖 oar_resources_init — bestie edition 💖

okay so this lil cutie lives in the OAR commands manual (section 1), and it's here to help you set up your OAR resources without losing your mind. periodt.

✨ NAME ✨

oar_resource_init — connect to a whole list of hosts, snoop their system info, and build the matching OAR resources for you. it's giving "I did the paperwork so you don't have to" 💅

---

🌸 SYNOPSIS 🌸

oar_resource_init [options] <hostfile>

---

🦋 DESCRIPTION 🦋

So here's the tea. 🍓 Hosts get read one per line from hostfile — and bestie, that file must be readable by user oar — or from STDIN, if hostfile is literally just -.

Every single host in hostfile has to have the "oar-node" service started. Like, no exceptions. The command connects to those hosts via SSH on the port 6667. 🫶

Then it does one of two things, your choice:

• it generates a script you can run later, or
• it directly executes the OAR commands — that's oarnodesetting and oarproperty. 👑

Here's the resource hierarchy it assumes:

host > cpu > core

Or, if the -T option is set:

host > cpu > core > thread

The mem property gets set along with the hierarchy. ✨

Other properties? Not set. Nope. But the generated script can be modified to do it, or you can just use the oarnodesetting command afterward to set them yourself. main character energy, honestly.

🎀 OPTIONS 🎀

• -H — Handle HyperThreading. Unless -T is used, every logical cpus (threads) belonging to a same core will be assigned to the cpuset internal property, separated by commas.
• -T — Use the thread property for HyperThreading (imply -H).
• -o [file] — Script filename.
• -x — Execute the script at the end and remove it.
• -y — Assume "yes" as answer to all prompts and run non-interactively.
• -v — Print the generated script.
• -e [path] — Path to the ssh command.
• -n [path] — Path to the oarnodesetting command.
• -p [path] — Path to the oarproperty command.
