    Integrating Practical2009 Integrating Practical2009 Presentation Transcript

    • 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
    • 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
    • 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
    • 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)
    • 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)

    • Text can have white space – make sure you find all of it tex t 12
    • Search space (conceptual view, not actual) 10000 Computed data area -10000 10000 GridSAM GT4 UNICORE Condor gLite Stored data area -10000
    • 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
    • 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
    • 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
    • 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  Use the query-all-notes command in the Globus installation  Instructions: 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  gratingWeb/integrating.html
    • Reporting colums  Browse to  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
    • 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
    • Instructions Technology-specific instructions for the integrating practical: Submission: (When a pillar is found, submit it to this website)  Condor: 2. GridSAM: 3. gLite: 4. Globus: 5. UNICORE: 6. OGSA-DAI: 7. Semantic Grid 20
