Mission: This resource will provide a comprehensive study of scalable and parallel computer architectures for achieving a proportional increase in performance with increasing system resources. Scalable architectures delivering a sustained performance are desired in both sequential and parallel computers. Vision: This book is associated with advanced architectural design and parallel programming techniques. It offers a balanced treatment of theory, technology and architecture. It primarily focuses on parallelism, scalability and programmability. Course objectives: 1. Gaining the architectural concepts of RISC and CISC 2. Architectural implementation of pipeline as well as multiprocessor systems 3. Network topologies (Static and Dynamic) along with interconnection mechanisms 4. Cache memory mapping policies along with updating schemes 5. Virtual memory concepts along with page replacement mechanisms 6. Concepts of I/O subsystems 7. Cloud computing.
