The document describes an integrating practical simulation involving searching for pillars on a surface to find words of wisdom. Participants are expected to write programs to interface tools to search across the surface for pillars and plaques, read words on the plaques, recognize patterns, and make use of capabilities. Instructions are provided for using scanner tools to search areas and submitting findings, as well as technology-specific instructions. Participants will report results and insights gained from searching strategies and technology evaluations.

e-Science Research
 Collaboration between scientists (your group)
 Exploring large amounts of Data to find particular patterns of interest
 Astronomy
 Particle physics
 Biomedicine
 Geophysics
….
 Using results of other researchers’ work

4. Hints
Hints are found
using OGSA-DAI
Hints look like this (in relational form):
x y form technology
12.554886 2.295809 CALCULATE
764.082765 91.932643 DATA OMII
Boundary of the Surface
 Hints, (Xi, Yi), obtained by “previous research teams” - may not be
completely trustworthy!
 Hints tell you which technology to use and the form of the data
(calculated on the fly or stored as files and accessed via metadata)

5. Real search space
characteristics
 In real life
 Noise is much larger and pervasive (ie. Top of pillars)
 Ratio of signal to noise is usually larger
 Search spaces generally larger
 Don’t normally know the complete parameters of your search
space
 E.G. Boundaries & alignment
 So, here, we do not need statistics to analyse the
patterns
 Do not need to run complex models
 You are being given the searching tool (may often be the
case in real life)

14. Framework
Expected to
 Write program(s) / script(s)
 To run explorations across Surface,
 E.G. interfacing tools for displaying result with
technologies that deliver those results
 to find
 Pillars, then plaques
 Do visualisation on Plaques to read Wisdom
Words
 Recognise the pattern
 Making full use of capabilities

15. Scanner tool
 Use the Scanner tool to search for a pillar in a given area
 From the command line,
 java -jar sfkscan-XXX.jar <x1> <y1> <x2>
<y2> <step_size>
 (XXX = technology name: glite globus condor
unicore gridsam)
 X1y1 = bottom left, x2y2 = top right
 If a pillar is found in the given area, the word on the
plaque will be printed on the screen.
 It can be saved in a text file to view better if the word
wraps on the screen.
 This can be done through redirecting the output to a file.

16. Parameters
 Area = -10,000 to 10,000
 Step size range = 0.0001 -> 0.1
 Each technology has sample pillar that
you will be given.
 30 pillars in total

17. Semantic Grid Integrating Practical
 Objectives
 Use the lessons learned in the Semantic Grid Practical
 Query the metadata stored in a Globus container
 Procedure
 After you find all the words hidden in the pillars…
 Connect to issgc-client-01.polytech.unice.fr
 Use the query-all-notes command in the Globus installation
 Instructions: http://www.dia.fi.upm.es/~ocorcho/ISSGC2009/
web/index_integrating.html
 Results
 The results are the name of the elements you were querying
to the Metadata Query Service: 8 words
 Combining these words with the previous ones from the
pillars you get the final solution

18. Reporting colums
 Browse to
http://dc06.nesc.ed.ac.uk:8080/sfk/
 To enter discovered pillars:
 Group - this is your group number, (do not
add for other groups!)
 Text - the whole text you found on the pillar
(need to find all of it)
 x1, y1, x2, y2 - specify a bounding box that
includes all of that text
18

19. Reporting your results
 Each team will get
 5 minutes during session 56
 2 minutes to change over and get started!
 Maximum number of slides
 Title
 4 others
 What you learnt and insights gained
 Results of the search
 Technologies used
 Evaluation of technologies
 Evaluation of your strategies
 Team organisation, roles and how they worked
