Current commercial CPUs have hardware support for speculative lock elision (SLE). SLE tries to elide the lock by speculatively executing lock protected critical section. If the speculation fails, SLE acquires the lock and re-executes the critical section non-speculatively. Latest Intel CPUs implement SLE and hardware transactional memory (HTM) where SLE uses HTM transactions to speculatively execute critical sections. HTM only supports bounded size transactions where non-conflicting transactions...
