From the Gospel of the Saints Carl Ian

• Large-scale applications in the 21st Century
• will involve
• the communication with and the coordination of a
  large number of geographically dispersed
  information sources
• will require an environment the supports
• Reliable
• Fault-tolerant
• Highly distributed
• Heterogeneous
• Scalable
• computing capabilities

Question

• Is it possible to set up a brokerage system for
  making idle resources of anonymous users of the
  Web accessible for Grid Computing ?

A brokerage system..

Electrical Grid

• Electric power applications have caused radical
  changes into the individual and collective life
  of men.

Internet
The natural carrier for Grid Applications
(????)
The everymans supercomputer (????)

• Internet connects tens of millions of computers
• A very small percentage is engaged in the Global
  Computing efforts

Lack of

• Security

• A unified framework

• Incentive to participate

Building ofa brokerage system..
Who pays for that ???
Foundation for the Grid Economy
12
Who pays for this ??

So, just to conclude with a comparison with the
Electrical Grid..

• Where we are ????

Oh, mon Dieu !
.and in the future, I imagine a worldwide Power
(Electrical) Grid ...
What ?!?! This is a mad man

Grid Computing A New Wave ?
What will be the dominant grid approach in the
next future ??
19
Trends
It is very difficult to predict the future and
this is particular true in a field such as
Information Technology
I think there is a world market for above five
computers. Thomas J. Watson Sr., IBM Founder,

Trends
GRIDsThe time is exciting but the way is hard
and long.
EU will gain momentum or risk to lag behind..
