Introduction

• Multiprocessor system is an interconnection of two or more CPUS with memory and input-output equipment
• The components that forms multiprocessor are CPUS IOPS connected to input -output devices,and memory unit that may be partitioned intoanumber of separate modules.
• Multiprocessor are classified as multiple instruction stream, multiple data stream (MIMD) system.

Why Choose a Multiprocessor?

• A single CPU can only go so fast, use more than one CPU to improve performance
• Multiple users
• Multiple applications
• Multi-tasking within an application
• Responsiveness and/or throughput
• Share hardware between CPUS

Loosely-coupled multiprocessor

• Loosely-coupled multiprocessor systems (often referred to as clusters)are based on multiple standalone single or dual processor commodity computers interconnected via communication system a high speed

• Loosely-coupled multiprocessor is also known as distributed memory.

• Example A Linux beowulf cluster
