Потоки

Потоки позволяют программам выполняться на нескольких ядрах процессора.

Определено в файле <thread>
thread (C++11)	управляет отдельный поток Original: manages a separate thread The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions. (класс)

Взаимные исключения (мьютексы)

Алгоритмы взаимных исключений предотвращают одновременный доступ нескольких потоков к разделяемым ресурсам. Это позволяет исключить гонку данных и обеспечить синхронизацию между потоками.

Условные переменные

A condition variable is a synchronization primitive that allows multiple threads to communicate with eachother. It allows some number of threads to wait (possibly with a timeout) for notification from another thread that they may proceed. A condition variable is always associated with a mutex.

Определено в файле <condition_variable>
condition_variable (C++11)	provides a condition variable associated with a std::unique_lock (класс)
condition_variable_any (C++11)	provides a condition variable associated with any lock type (класс)
notify_all_at_thread_exit (C++11)	schedules a call to notify_all to be invoked when this thread is completely finished (функция)
cv_status (C++11)	lists the possible results of timed waits on condition variables (перечисление)

Futures

The standard library provides facilities to obtain values that are returned and to catch exceptions that are thrown by asynchronous tasks (i.e. functions launched in separate threads). These values are communicated in a shared state, in which the asynchronous task may write its return value or store an exception, and which may be examined, waited for, and otherwise manipulated by other threads that hold instances of std::future or std::shared_future that reference that shared state.
