HOSTGROUP(5)

💖 HOSTGROUP — host group entry file format 💖

okay bestie, so this is HOSTGROUP(5) from the Grid Engine File Formats manual, and honestly? it's giving "organize your hosts or perish" and we're obsessed 💅

✨ NAME ✨

hostgroup — the host group entry file format. that's it, that's the vibe 🎀

---

🌸 DESCRIPTION 🌸

so a host group entry does exactly what it says on the tin: it merges host names into groups. each host group entry file defines one group. one file, one group, main character energy only 👑

and here's the cute part — inside a group definition file you can also reference other groups. those referenced groups are called subgroups, and you reference one by putting the @ sign as the first character of the name. periodt.

want to see what's already configured? you can peep the list of currently-configured host group entries with the qconf(1) -shgrpl option. then to see what's inside each of those listed host group entries, use the -shgrp switch. the output follows the hostgroup format description (aka this very page, we love a self-referential queen 💖).

and if you wanna create new host group entries or modify existing ones, that's the -ahgrp, -mhgrp, -dhgrp and -?attr options on qconf(1). slay.

⚠️ note bestie: Grid Engine lets you use backslashes (\) to escape newline characters. the backslash and the newline get replaced with a space character before any interpretation happens. so don't be weird about it.

🦋 FORMAT 🦋

a host group entry contains the following parameters:

🎀 group_name 🎀

the group_name defines the host group name. host group names have to begin with an @ character — this is exactly as explained for hostgroup_name in sge_types(5). no @, no entry, sorry babe 😭

💜 hostlist 💜

the names of all hosts and host groups (see host_identifier in sge_types(5)) that are members of the group. only whitespace is allowed as a list separator — no commas, no vibes-based delimiters, just spaces fr fr. the default value for this parameter is NONE.

📌 note again bestie: if the first character of the host_identifier is an @ sign, the name is used to reference a hostgroup(5) which gets taken as a subgroup of this group. it's giving nesting, it's giving hierarchy, we stan 🧚

🌈 EXAMPLE 🌈

this is a typical host group entry, and honestly it ate:

group_name @bigMachines

hostlist @solaris64 @solaris32 fangorn balrog

so this entry defines a new host group called @bigMachines. inside this host group you've got the host fangorn, the host balrog, and all the members of the host groups @solaris64 and @solaris32. iconic. no cap. 💅
