__gnu_parallel::omp_loop_tag(3cxx)

💅 NAME 💅

__gnu_parallel::omp_loop_tag — bestie, this tag is literally telling the compiler "hey, run this in parallel with OpenMP dynamic load-balancing, k?" at compile time. No cap. 🫶

(also, hi, this is a page from the libstdc++ manual, section 3cxx — more on that at the very bottom 💖)

---

✨ SYNOPSIS ✨

#include <tags.h>

Inherits __gnu_parallel::parallel_tag — so it's giving "I'm a parallel tag, but make it OpenMP" 👑

🎀 Public Member Functions 🎀

• _ThreadIndex __get_num_threads() — figure out how many threads we actually want, iykyk
• void set_num_threads(_ThreadIndex __num_threads) — set the desired number of threads, periodt

---

🌸 Detailed Description 🌸

__gnu_parallel::omp_loop_tag recommends parallel execution using OpenMP dynamic load-balancing at compile time. That's the whole vibe. It's a little tag struct whose entire main character energy is "please parallelize me, and do the load balancing dynamically with OpenMP" ✨🔥

💜 Member Function Documentation 💜

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

Find out the desired number of threads. Literally its only job, and it ate. 💅

Returns

Desired number of threads. ⭐

Referenced by — okay so this is a lot of references, but here's the full list, no skipping, fr fr:

• __gnu_parallel::__parallel_sort()
• __gnu_parallel::__parallel_sort()
• __gnu_parallel::__parallel_sort()
• __gnu_parallel::__parallel_sort()
• __gnu_parallel::__parallel_sort()
• __gnu_parallel::__parallel_sort()
• __gnu_parallel::__parallel_sort()

(yes, that's the same function seven times — that's exactly how the original lists it, and we do not merge them around here 😭)

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

Set the desired number of threads. Iconic behaviour, honestly.

Parameters

• __num_threads — the desired number of threads 🎀

Generated automatically by Doxygen for libstdc++ from the source code. So nobody hand-wrote this one, it's giving ✨auto-generated realness✨ 🙈

💀 real talk, bestie: __get_num_threads() and set_num_threads() are inherited from __gnu_parallel::parallel_tag, so they live over there — this page just shows them so you're not lost. 🫶

and that's the whole page, bestie — stay hydrated, read your tags, and remember: compile-time vibes only 💖✨🎀🦋🌸💅🫶😭🔥👑🌈⭐💀🙈🍓🧚💜
