Application: WAM
• WAM = Global ocean Wave prediction Model• Field:
– Earth Sciences (Marine)
• Objective:– forecast wave conditions around Ireland on a fine
resolution, using high resolution winds obtained as boundary conditions from Met Eireann, for the periods 2020-2030 and 2050-2060
• Resolution:– 5 km (Met Eireann: 25 km)
• Code: Fortran
Itacuruçá , First EELA-2 Grid School, 13.11.2008 3www.eu-eela.eu
Difficulties
• Input Data:– Bathymetry
160 KB
– High Resolution Wind Fields 60 MB per file 1 file per month 100 years
Total size: 72 GB
– Wave Boundary Conditions 50 MB per file 2 files per day 100 years
Total size: 3.6 TB

Done
• Transfer code and sample input data to a SE• Script to:
– download code and data from SE,– Rebuild directory structure as required,– Execute model on a working node,– Store outputs on SE.
• AMGA catalogue for processed data• Script to check whether data have been processed• Command line user interface:
– Script to generate JDL files and submit jobs– Script to check jobs status– Script to download outputs

Synergy with Other Teams
• HMMER Team– Similarities in work flows and user interfaces– Build on user interface developed by Daniel and Michael
• Satellite Images Team– Potential for using same approach for seabed classification
using large multi/single beam data

Next Steps
• Benchmarking [3-4 Months]• Production [6-8 Months]
– Transfer 3.6 TB of data to the grid– Deploy WAM on the EELA Grid
• Develop a user interface using GENIUS [9-12 Months]
