1 Edinburgh - at the Frontiers of e-Science
Richard Kenway

2 discovery science e-science = searching for the unknown in vast amounts of data

3 electronic ‘needle in a haystack’
to find the Higgs boson and explain where mass comes from and … are not enough you need to build a Grid

4 LHC computing challenge
assumes PC = ~ 25 SpecInt95 ~PByte/sec Online System ~100 MByte/sec Offline Farm ~20,000 PCs one bunch crossing per 25 ns 100 triggers per second each event is ~1 MByte ~100 MByte/sec Tier 0 CERN Computer Centre >20,000 PCs ~ Gbit/sec or Air Freight HPSS Tier 1 US Regional Centre Italian Regional Centre French Regional Centre RAL Regional Centre HPSS HPSS HPSS HPSS Tier 2 ScotGRID++ ~1000 PCs Tier2 Centre ~1000 PCs Tier2 Centre ~1000 PCs Tier2 Centre ~1000 PCs ~Gbit/sec Tier 3 Institute ~200 PCs Institute Institute Institute physicists work on analysis “channels” each institute has ~10 physicists working on one or more channels data for these channels is cached by the institute server Physics data cache Mbit/sec Tier 4 Workstations

5 the web on steroids 1989: Tim Berners-Lee invented the web
so physicists around the world could share documents 1999: Grids add to the web computing power data management big instruments (eventually) sensors

6 a new global infrastructure
information on demand - like power from a socket sensor nets data archives computers software colleagues instruments the Grid is an emergent infrastructure to deliver dependable, pervasive and uniform access to globally distributed, dynamic and heterogeneous resources problems of scalability, interoperability, fault tolerance, resource management and security

7 underpinning technology

8 why now? for 50 years, we have been riding the crest of a IT wave and
3.5 million users 22 teraflops for 50 years, we have been riding the crest of a IT wave building vast untapped global resources hundreds of millions of (mostly) idle PCs and big science is facing a data tsunami

12 Quality of Service on the internet
aim to distinguish types of traffic high priority fast lanes low priority slow lanes hard to configure intersim simulation tool detailed model of network understand and validate configurations EPCC + Cisco Systems

13 Grid applications

14 whole-system simulations
braking performance steering capabilities traction dampening capabilities landing gear models lift capabilities drag capabilities responsiveness wing models deflection capabilities stabilizer models airframe models crew capabilities - accuracy - perception - stamina - reaction times - SOP’s human models thrust performance reverse thrust performance fuel consumption engine models NASA Information Power Grid: coupling all sub-system simulations

15 global in-flight engine diagnostics

19 emergency response teams
bring sensors, data, simulations and experts together wildfire: predict movement of fire & direct fire-fighters also earthquakes, peacekeeping forces, battlefields,… National Earthquake Simulation Grid Los Alamos National Laboratory: wildfire

20 Earth observation ENVISAT ground deformation prior to a volcano

21 Grid development

22 data, information and knowledge
virtual data …from the grid from a database somewhere computed on request measured on request automated knowledge …from computer science data: un-interpreted bits and bytes information: data equipped with meaning knowledge: information applied to solve a problem

23 three layer Grid abstraction
Knowledge Grid Data to Knowledge Control Information Grid Computation/ Data Grid

24 the Grid as an evolving concept
enabler for transient ‘virtual organisations’ anatomy: a software infrastructure that enables flexible, secure, co-ordinated resource sharing among dynamic collections of individuals, institutions and resources Foster, Kesselman & Tuecke (2001) evolution of and integration with web services physiology: everything is a Grid service ie a service that conforms to a set of conventions for management and exchanging messages Foster, Kesselman, Nick & Tuecke (2002) Global Grid Forum: define a standard Grid architecture big business and big science working together

33 imagine a political party reception…

34 the leader enters…

35 a rumour is started…

36 and propagates across the room

37 another technological revolution is underway
from little acorns… “ It is worth noting that an essential feature of the type of theory which has been described in this note is the prediction of incomplete multiplets of scalar and vector bosons. ” Peter Higgs (1964) “ … a billion people interacting with a million e-businesses with a trillion intelligent devices interconnected ” Lou Gerstner, IBM (2000) another technological revolution is underway
