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.

- 1. Integrating practical Author/Presenter: David Fergusson Technology Masters – Alain Roy, Ben Clifford, Rebbeca Breu, Carlos Aranda, Emidio Giorgio, Tony Calanduci, Steve Crouch, Tilaye Alemu SFK Master – Ted Wen
- 2. SfK = simulation of typical 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
- 3. The Pillars of Wisdom background Pillar – Overrides background Rectangular Constant height Aligned with x-y axis Plaque – Overrides background Rectangular Constant height > Or < pillar height Aligned with x-y axis Word or phrase – Overrides background Rectangular Wise Words Constant height Total of 20 Pillars > Or < plaque height Aligned with x-y axis
- 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. 15
- 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 16
- 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 http://www.dia.fi.upm.es/~ocorcho/ISSGC2009/Inte gratingWeb/integrating.html
- 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
