1 From web to grid: The future of scientific computing? Neasan ONeill GridPP Dissemination Officer

2 Your university or experiment logo here CERN In The Beginning …

3 Your university or experiment logo here The LHC

4 Your university or experiment logo here The Experiment 4 Experiments ALICE CMS LHCbATLAS

5 Your university or experiment logo here What actually happened at the big bang? Answering other questions How does gravity work? How do particles have mass? Where is the rest of the universe? Answering the big question A Discovery Machine

6 Your university or experiment logo here Combined they will create 15PB of Data every year Thats the equivalent of 22 Trillion Sheets of A4 More than any single, current, system can handle A Data Challenge

7 Your university or experiment logo here The Problem Solution needs to be: Able to handle massive amounts of data Able to process large computing jobs Relatively inexpensive Simple to use Accessible 24/7 Easily upgraded

8 Your university or experiment logo here Super Computers? So we just build them bigger? But: Expensive Inaccessible Easily outdated

9 Your university or experiment logo here The Internet? The physical network which connects the worlds computers allowing them to communicate A Solution

10 Your university or experiment logo here Tools built upon the Internet Worldwide Web File Sharing networks BOINC e.g.

11 Your university or experiment logo here The World Wide Web The Web specifically designed by scientists at CERN to help with their work

12 Your university or experiment logo here The Next Stage Build a new tool –The computers in the institutions are already connected –They already share files How about sharing everything?

13 Your university or experiment logo here The Electricity Grid Always on As much or as little as you need on tap Where/how power is generated is irrelevant to the end user Just plug in and go

14 Your university or experiment logo here A Computing Grid Always on As much or as little as you need on tap Where/how computing power is generated is irrelevant to the end user Just plug in and go

15 Your university or experiment logo here Before Distributed computing has been available to scientists for some time but: The use of different sites has to be negotiated by each scientist individually. They need a separate account on each system. Jobs have to be submitted and results collected back by hand. Distributed computing can mean the user has a lot of work to do to get any work done

16 Your university or experiment logo here Middleware lets users simply submit jobs to the Grid without having to know where the data is or where the jobs will run. The software can run the job where the data is, or move the data to where there is CPU power available. Using the Grid and middleware, all the user has to do is submit a job and pick up the results. After

17 Your university or experiment logo here Technical details Operating System – Scientific Linux CERN edition (SLC5) Middlewares: gLite – Developed during the Enabling Grids for EsciencE projects, used across most of Europe, Australasia and Southern and Central America. ARC - Advanced Resource Connector, run by the Nordic countries (and glasgow). UNICORE - UNiform Interface to COmputing Resources, grid middleware for supercomputers Globus Toolkit – Used by the Open Science Grid in America

18 Your university or experiment logo here wLCG Worldwide LHC Computing Grid 130 computing centres 34 countries 100,000 CPUs

19 Your university or experiment logo here More than the LHC SuperB is a Super Flavour Factory, this means that they will be looking for new physics relating to the changes in the properties of elementary particles like quarks. It will be built outside Rome. T2K, in Japan, studies neutrino oscillations by generating a beam of neutrinos and directing it towards the Super-Kamiokande detector 300Km away. MICE is the foundations for a neutrino factory. The theory behind creating a steady beam of muons (which decay neutrinos) is quite well understood but controlling various parameters of the muons isn't.

20 Your university or experiment logo here EGI European Grid Initiative users 243,020 CPUs 317 sites 61PB tape 175 VOs 40PB disk 52 countries15m jobs/month

21 Your university or experiment logo here EGI Collaboration NGINGI NGINGI NGINGI NGINGI Research Community Research Community Research Community Research Community EGI.eu Research Community

22 Your university or experiment logo here Multidisciplinary WISDOM Challenges: –Avian Flu 100 years work done in 4 weeks –Malaria 50% of computing power provided by GridPP Digital Libraries –Using the Grid to preserve cultural heritage by digitising and storing the information. The distributed storage makes access easier. ASTRA –Archaeological and musical project Modelling ancient instruments, such as the Epigonion, Salpinx and Kithara to make it easier for researchers and musicians to study long dead instruments and music Collaboration with CityDance –A Washington DC based dance troupe used a technique for converting seismic activity to sound to create music for a piece they were working on The technique called volcano sonification is usually used to predict earthquakes and is very CPU intensive so the Grid is used to do the number crunching

23 Your university or experiment logo here Based at 20 UK universities, and CERN, they are building the UK arm of the wLCG GridPP is a collaboration of Particle Physicists and Computing Scientists Grids in the UK

24 Your university or experiment logo here University Of Birmingham University Of Bristol University Of Cambridge University Of Oxford Rutherford Appleton Laboratory Warwick University University of Sussex Lancaster University University Of Liverpool University Of Manchester University Of Sheffield Durham University University Of Edinburgh University Of Glasgow Brunel University Imperial College London Queen Mary, University Of London Royal Holloway, University Of London University College London Swansea University GridPP

25 Your university or experiment logo here Numbers 20 Institutes 100+ Individuals 10,000+TB of storage Equivalent of ~24,000 desktop computers

26 Your university or experiment logo here Innovation in outreach The e-ScienceTalk project communicates the success stories of e-Infrastructures to policy makers, general public, scientists and students
