__gnu_para...p_loop_tag(3)

💖 NAME 💖

__gnu_parallel::omp_loop_tag — bestie, this lil tag is literally a compile-time note that says "yo, run this in parallel with OpenMP dynamic load-balancing." That's it. That's the whole vibe. ✨

Oh and also, the manual page it lives on is __gnu_para...p_loop_tag(3) (yes the name is truncated, we don't talk about it, it's giving ✨mystery✨), and the library it belongs to is libstdc++. 🫶

🌈 SYNOPSIS 🌈

#include <tags.h>

It inherits from __gnu_parallel::parallel_tag, so all the inherited goodies come along for the ride. 👑

🎀 Public Member Functions 🎀

• _ThreadIndex __get_num_threads () — figure out how many threads we're wanting around here. 🔢
• void set_num_threads (_ThreadIndex __num_threads) — tell it how many threads you want. 🎚️

---

🦋 Detailed Description 🦋

So basically: it recommends parallel execution using OpenMP dynamic load-balancing at compile time. Not runtime, bestie — compile time. It's the tag you slap on when you already know what you want before the program even exists. no cap. 💅

🌸 _ThreadIndex __gnu_parallel::parallel_tag::__get_num_threads () [inline], [inherited] 🌸

Find out the desired number of threads. That's the whole job. She's simple, she's iconic. 🧚

Returns

• Desired number of threads. 🎯

Referenced by __gnu_parallel::__parallel_sort(), __gnu_parallel::__parallel_sort(), __gnu_parallel::__parallel_sort(), __gnu_parallel::__parallel_sort(), __gnu_parallel::__parallel_sort(), __gnu_parallel::__parallel_sort(), and __gnu_parallel::__parallel_sort().

Not me listing __gnu_parallel::__parallel_sort() seven separate times 😭 that's not a typo, that's literally what the page says, and I am not about to merge them. Facts stay facts, periodt. 💀

💜 void __gnu_parallel::parallel_tag::set_num_threads (_ThreadIndex __num_threads) [inline], [inherited] 💜

Set the desired number of threads. You're the main character, you decide. 👑

Parameters

• __num_threads — Desired number of threads. 📌

And that's the whole page, bestie! 🎀 This beauty comes to you courtesy of libstdc++ (that's the library it's from — the footer doesn't hand over a version number or a date, so we're keeping it exactly that vague, iykyk), on the manual page __gnu_para...p_loop_tag(3). Go forth and parallelize, but make it compile-time. 🌈💖🦋
