Parallel Computing

• Multi-Core• Distributed Systems• SOA & WebServices• Transaction, Session, Queue, Event, Interrupt• User Experience over User Interface• Maximize performance: No Free Work Unit• Best performance: No I/O Wait

Advantages of Multi-Core

• Low Power Consumption• Extended battery life• Less heating• Smaller and lighter devices• Software replaces custom hardware!

Challenges With Multi-Core

• Design Patterns• STL• Our existing code• Tools• Online Samples• My Work Routine

Making Coffee

• Hot Water• Small Glass• Coffee• Milk• Sugar• Cookies

Object Oriented Design: Inheritance

Liquid Dissolvent

Object Oriented Design: Methods

• Make Hot• Is Hot?• Pour to glass• Is spilled?

Object Oriented: Steering

-> Mix with Sugar -> Mix with Water

-> Pour

-> Drop

-> MIX???

Actions

• Mix is an Action• “What Does” instead of “What is”• Relevant Methods Added• System Design!

Making Coffee in the real world

• Boil the water• Until water is hot:• Go to the kitchen and get the coffee, milk, sugar• If water still not hot read a book• Mix the sugar, coffee and hot water• Add the milk• Go get 5 cookies of the 42 you made yesterday

Task Oriented Design

• Is The Missing Link• Flow Charts before Object Diagrams• Locating Flow Control Bugs (Random Bugs)• Maximizing CPU Power• Keep Responsive for good UX
