More processors means more work in less time

is the ability to continue providing service proportional to the level of surviving hardware

Multiprocessors can be divided into symmetric and Asymmetric

This scheme defines a boss-worker relationship

Used by most systems

No boss-worker relationship

Worker processors look to the boss for instruction or have predefined tasks

All processors are peers, where each processor can perform any task

The boss processor schedules and allocates work to the worker processors

Multicore Systems: Multiple computing cores on a multiple chips

Multicore Systems: Multiple computing cores on a single chip

multiple chips with single cores is More efficient than Multicore Systems

…..communication is faster than … communication

One chip with multiple cores uses …power than multiple single-core chips

All Multicore systems are multiprocessor systems

All multiprocessor systems are multicore systems

Multiprocessor systems Also known as loosely-coupled systems

Also known as loosely-coupled systems

Composed of two or more individual systems (or nodes)

Each node may be a single processor system or a multicore system

Clustered computers share storage and are closely linked via a (((LAN)))
