Introduction
Though the migration from uniprocessor system to multiprocessing systems is not new, the world of parallel computers is undergoing a continuous change. Parallel computers, which started as high-end super-computing systems for carrying out huge calculations, are now ubiquitous and are present in all mainstream architectures for servers, desktops, and embedded systems. In order to design parallel architectures to meet programmer's needs and expectations more closely, exciting and challenging changes exist. The three main areas which are being considered by scientists today are: cache coherence, memory consistency and synchronization.
