Distributed systems are groups of networked computers which share a common goal for their work. Parallel Computer Architecture is the method of organizing all the resources to maximize the performance and the programmability within the limits given by technology and the cost at any instance of time. Memory in parallel systems can either be shared or distributed. Advantages: . 10. An N-processor PRAM has a shared memory unit. Concurrency is a property of a system representing the fact that multiple activities are executed at the same time. Each of these nodes contains a small part of the distributed operating system software. Computer systems based on shared memory and message passing parallel architectures were soon followed by clusters and loosely coupled workstations, that afforded flexibility and good performance for many applications at a fractional cost of .
