Distributed and Parallel Systems - Term Paper ExampleA parallel system is a computer with more than unity processor for parallel processing. Although there are many kinds of parallel computers, they are basically distinguished by the kind of interconnection between processor, known as processing elements (PES), and the remembrance. One major way to classify parallel computers is based on their memory architectures. Shared memory based parallel computing systems take on multiple processors that access all available memory as a global address space. Distributed system is a network of a set of asynchronously affiliated computing devices. Communication in DS is either through shared memory or through messages. In wide-spread distributed systems, work and information are physically distributed, implying that computing needs should be distributed. Along with improvement in response time, this system contributes to offering a local control over data. With this solid background of multi processor systems, parallel computing, distributed systems and shared memory speed-up performance law such as the Amdahls law was introduced to throw light on algorithm design for speed-up and operational susceptibility of parallel system. Concurrency is another important factor which enables distributed systems to share memory and to better understand its execution, Dining philosophers algorithm Bullys algorithm and Logical clocks were introduced. 2. Amdahls LawThe memory organization of parallel system also has a profound impact on algorithm design. In systems in which memory
