Language Support for Concurrency: Transcript


Ken Birman 1 Synchronization paradigms Weve looked at critical sections Really a form of locking When one thread will access shared data first it gets a kind of lock This prevents other threads from accessing that data until the first one has finished. This motivated an ongoing shared effort by the standards committees to specify concurrent behaviour in the next versions of both languages They aim to provide strong guarantees for racefree programs together with new but subtle relaxedmemory atomic Sadhna Kumari.
