 What is Grid and eScience
 The UK eScience Programme
 The Global Programme
Take Home
 Grid is the latest attempt to do global
 distributed computing.
 Strong application pull.
 Strong industrial support.
 The technology is not ready (yet).
 It isn‘t going away.
 The UK is a leader & highly involved.
 The OST is committed to eScience
Why Grids?
  Large-scale science and engineering are done
  through the interaction of people,
  heterogeneous computing resources,
  information systems, and instruments, all of
  which are geographically and organizationally
  dispersed.
  The overall motivation for ―Grids‖ is to
  facilitate the routine interactions of these
  resources in order to support large-scale
  science and engineering.
                             From Bill Johnston 27 July 01
CERN: Large Hadron Collider (LHC)
Raw Data: 1 Petabyte / sec
Filtered 100Mbyte / sec = 1 Petabyte / year = 1 Million CD ROMs




                                  CMS Detector
Why Grids?
  A biochemist exploits 10,000 computers to
  screen 100,000 compounds in an hour;
  A biologist combines a range of diverse and
  distributed resources (databases, tools,
  instruments) to answer complex questions;
  1,000 physicists worldwide pool resources for
  petaop analyses of petabytes of data
  Civil engineers collaborate to design, execute,
  & analyze shake table experiments

                               From Steve Tuecke 12 Oct. 01
Why Grids? (contd.)
  Climate scientists visualize, annotate, &
  analyze terabyte simulation datasets
  An emergency response team couples real
  time data, weather model, population data
  A multidisciplinary analysis in aerospace
  couples code and data in four companies
  A home user invokes architectural design
  functions at an application service provider


                                  From Steve Tuecke 12 Oct. 01
 What is the Grid?
― Grid computing [is] distinguished from
   conventional distributed computing by its
   focus on large-scale resource sharing,
   innovative applications, and, in some
   cases, high-performance orientation...we
   review the "Grid problem", which we
   define as flexible, secure, coordinated
   resource sharing among dynamic
   collections of individuals, institutions, and
   resources - what we refer to as virtual
   organizations."
 From "The Anatomy of the Grid: Enabling Scalable Virtual
         Organizations" by Foster, Kesselman and Tuecke
What is the Grid?
Resource sharing & coordinated problem solving
in dynamic, multi-institutional virtual
organizations
On-demand, ubiquitous access to computing,
data, and all kinds of services
New capabilities constructed dynamically and
transparently from distributed services
No central location, No central control, No
existing trust relationships, Little
predetermination
Uniformity
Pooling Resources
e-Science and the Grid
‗e-Science is about global collaboration in
  key areas of science, and the next
  generation of infrastructure that will
  enable it.‘
‗e-Science will change the dynamic of the
  way science is undertaken.‘
John Taylor,
Director General of Research Councils,
Office of Science and Technology
Classical Grids
  Classical Grids
  emphasise sharing of
  physical resources.
  Existing Grid
  middleware (e.g.
  Globus, Condor,
  Unicore) allows
  resource discovery,
  resource allocation,
  data movement,
  certification …

Reality Checks!!
The Technology is Ready
   Not true — its emerging
      Building middleware, Advancing Standards, Developing,
         Dependability
        Building demonstrators.
        The computational grid is in advance of the data intensive
         middleware
        Integration and curation are probably the obstacles
        But!! It doesn‘t have to be all there to be useful.
We know how we will use grid services
   No — Disruptive technology
      Lower the barriers of entry.
Take Home
 Grid is the latest attempt to do global
 distributed computing.
 Strong application pull.
 Strong industrial support.
 The technology is not ready (yet).
 It isn‘t going away.
 The UK is a leader & highly involved.
 The OST is committed to eScience
