19. 19 Running on Global Grids Aim for common interfaces and interoperability Slide taken from Juergen Knobloch

20. 20 Conclusion I have grossly omitted the Global Grid Forum… The “Grid” as a concept is being Globally adopted –Multitude of national and international initiatives There are several sizable grids which are continuously active –O(10) production level Grids world-wide representing O(10 000) CPUs –Diverse functionality High-throughput computing Interactive visualisation –Indication that grid technology is maturing Interoperability and common interfaces are real issues facing Global Grid activity –Sociology is at least as important as technology –Standards bodies, like the GGF, are becoming increasingly important
