the clue• Programming Life

– Coder and Coding– Designer and Architecture– Analyst and Software Engineer

• Grid in my way– Write Grid codes– Deploy Grid architecture– Draw our Grid dream!

Programming LifeCoder & Coding

• Coder Life:All start from “ Hello ,World! ”

• Interest from life– Torvalds’ Linux , Bill’s Basic

• Coding is Life but not a life tool

Programming LifeCoder & Coding

• Shortcomings– Best Coder ≠ Best Work

3 best coder did worst work, why?

– Best Coder ≠ Smartest WorkBest code work all days and nights, and still had to

face the failure, why?

– Best Coder ≠ Grid WorkThousands of coder in China but there’s no one

excellent Grid work, why?

Programming LifeCoder & Coding

• The solutions:• We need COOPERATIONS!• We need PLAN!• We need EXPIERENCES!

Programming LifeDesigner & Architecture

• Upgrade from coder• The difference between coding

and designing– Bad habit exists:

• coding first designing later• working in private single way• Garbage codes

Programming LifeDesigner & Architecture

• Far away from “hello ,world!”• What are you ,world?• We are the owner of the world!• Got clearly the needs ,the

architecture, the environment …

Programming LifeDesigner & Architecture

• Data Flow• Control Flow• Data structure• …

Programming LifeDesigner & Architecture

• Architecture is excellent but…• time is always not enough • Coder is always lazy • machine is always too slowly…

Programming LifeAnalyst & Software

• Coder say : I build the world• Designer say : I drive the world• Analyst say : I drive the whole

universe

Programming LifeAnalyst & Software

• More to think about– Peopleware, The Mythical MAN-MONTH

• Get the Demand• Analyzing• Deploy• Grasp the shedule• Test the module• Version control• Publish • Hazard control

Programming LifeAnalyst & Software

• More work on management to achieve the excellent goal

• More knowledge on time and space

• It’s just like life , complex life.

All of above• Bullshit? • ^_^ , Ok, let’s begin grid work

Grid• Grid in my way

– Write Grid codes– Deploy Grid architecture– Draw our Grid dream!

Grid in my way• What’s grid on earth ?

– Matrix? Control Human race – Skynet? Terminate Human race– God? Create Human race

Grid in my way• In fact …• I don’t know what on earth is it. • My supervisor give me the

direction , I just do GRID in my way.

Grid in my way• I think …

– It’s still coding , architecture , software engineering

– It’s still a foolish ,stupid guy• Now let me introduce Mr. Grid in my

mind

Grid in my way Write Grid code

• Environment:– JDk 1.4.1– Globus Toolkit 3.0.2– Vi– Internet Explorer – Cygwin ( Linux’s brother )

Grid in my way Write Grid code

• Start from “ Hello ,World “ :-)• How to “Hello, world” ?• Reference “ GT3 Tutorial “…• Let me see…

Grid in my way Write Grid code

Grid in my way Write Grid code

• Oh , my god …• Grid is hard to stay with : (

Grid in my way Deploy Grid architecture• Just like designer …• Only know the coding methods ,we

can do nothing , if we imagine that…

• Medicine , Science computing, space...

Grid in my way Deploy Grid architecture• Its Architecture .• Single Machine -> C/S -> B/S -> 3-tire -

> 4-tire -> …• Single coder -> Cooperation coders ->

designer+workshop -> multi-level develop -> …

• What happened ?

Grid in my way Deploy Grid architecture• So…• What can we do in the grid ?• If your service is depending on

Computing-share and data-share then you can use GRID

• If your service is depending on parallel computing ,then use GRID …

Grid in my way draw our grid dream

• China Grid ( next generation of CERNET)

• TeraGrid / Data Grid• Combine with our true life!

Grid in my way draw our grid dream

• One instance.• …

Grid in my way draw our grid dream

• Use grid to robotize our life• Welcome take part into our research!

Thanks !
