The quest for greater computational power is§never-ending. Recently, the architectural trend has§shifted from improving single-threaded application§performance to improving multi-threaded application§performance. Thus, multi-core processors have been§increasingly popular. To achieve concurrent execution§of threads on multi-core processors, applications§must be explicitly restructured to exploit§parallelism, either by programmers or compilers.§However, conventional parallel programming models may§introduce overhead due to synchronization and§communications among threads in multi-threaded§applications. This book presents three architectural§optimizations to improve thread-based synchronization§and communications support in multi-core processors.§Register-Based Synchronization (RBS) uses hardware§registers efficiently to provide synchronization§support in multi-core processors. Prepushing is a§software controlled data forwarding technique to§provide communications support in multi-core§processors. Software Controlled Eviction (SCE)§improves shared cache communications by placing§shared data in shared caches.
