💅 __gnu_para...GlobalData(3) — Library Functions Manual 🎀

okay so bestie, welcome to the group chat for __gnu_parallel::DRandomShufflingGlobalData — it's a libstdc++ page, and it's basically the shared notes doc that every thread reads from when they're doing a parallel_random_shuffle(). everyone gets a copy, nobody gatekeeps. slay. ✨

✨ NAME ✨

__gnu_parallel::DRandomShufflingGlobalData — the data that's known to every single thread participating in __gnu_parallel::parallel_random_shuffle(). it's giving "shared group chat, everyone's caught up." 💖

🌸 SYNOPSIS 🌸

🦋 Public Types

• typedef traits_type::difference_type difference_type — the difference type, inherited straight from traits_type. icon behavior.
• typedef std::iterator_traits< RandomAccessIterator > traits_type — the iterator traits for RandomAccessIterator.
• typedef traits_type::value_type value_type — the value type, also riding on traits_type.

🎀 Public Member Functions

• DRandomShufflingGlobalData (RandomAccessIterator &_source) — the constructor, bestie. takes a reference to the source.

👑 Public Attributes

• thread_index_t * bin_proc — number of the thread that will further process the corresponding bin.
• difference_type ** dist — two-dimensional array holding the thread-bin distribution.
• int num_bins — number of bins to distribute to.
• int num_bits — number of bits needed to address the bins.
• RandomAccessIterator & source — begin iterator of the source.
• difference_type * starts — start indexes of the threads' chunks.
• value_type ** temporaries — temporary arrays for each thread.

🌈 Detailed Description 🌈

template<typename RandomAccessIterator> struct
    __gnu_parallel::DRandomShufflingGlobalData< RandomAccessIterator >

Data known to every thread participating in __gnu_parallel::parallel_random_shuffle().

fr fr, that's the whole vibe — a templated struct on RandomAccessIterator, and it's the shared state everyone's working off. Definition at line 52 of file random_shuffle.h. periodt. 💅

⭐ DRandomShufflingGlobalData

template<typename RandomAccessIterator>
    __gnu_parallel::DRandomShufflingGlobalData< RandomAccessIterator
    >::DRandomShufflingGlobalData (RandomAccessIterator & _source) [inline]

Constructor. that's it, that's the whole note — it's [inline], it takes _source, and it does constructor things. no cap.

🍓 bin_proc

template<typename RandomAccessIterator> thread_index_t*
    __gnu_parallel::DRandomShufflingGlobalData< RandomAccessIterator
    >::bin_proc

Number of the thread that will further process the corresponding bin.

🦋 dist

template<typename RandomAccessIterator> difference_type**
    __gnu_parallel::DRandomShufflingGlobalData< RandomAccessIterator >::dist

Two-dimensional array to hold the thread-bin distribution.

Dimensions (num_threads + 1) x (num_bins + 1). love a little grid moment. 🔥

ok that's the whole page bestie, you ate. go forth and shuffle randomly, in parallel, with all your threads on the same page. 💅🦋
