Typedef Documentation

◆ speculative_spin_mutex

typedef interface7::internal::padded_mutex<spin_mutex,false> tbb::speculative_spin_mutex

A cross-platform spin mutex with speculative lock acquisition.

On platforms with proper HW support, this lock may speculatively execute its critical sections, using HW mechanisms to detect real data races and ensure atomicity of the critical sections. In particular, it uses Intel(R) Transactional Synchronization Extensions (Intel(R) TSX). Without such HW support, it behaves like a spin_mutex. It should be used for locking short critical sections where the lock is contended but the data it protects are not. If zero-initialized, the mutex is considered unheld.

◆ speculative_spin_rw_mutex

typedef interface7::internal::padded_mutex<tbb::spin_rw_mutex,true> tbb::interface8::speculative_spin_rw_mutex

A cross-platform spin reader/writer mutex with speculative lock acquisition.

On platforms with proper HW support, this lock may speculatively execute its critical sections, using HW mechanisms to detect real data races and ensure atomicity of the critical sections. In particular, it uses Intel(R) Transactional Synchronization Extensions (Intel(R) TSX). Without such HW support, it behaves like a spin_rw_mutex. It should be used for locking short critical sections where the lock is contended but the data it protects are not.
