Goal
End users want to:
Execute scientific applications
Using distributed systems to:
•
•
decrease time cost
Exploit storage & computational
capacities
use complex systems totally hidden
Do not want to :
learn any techniques that don't fit with scientific
area of them

Remote API:
•
Pro:
•
•
•
•
•
Servlet-technology
Language-independent
Hidden complexity
Easy API
Cont:
•
•
•
Workflow must be on „client side”
No workflow management
Tight range of functionalities

Terminology
Grid Application Developer
–
would like to have a Portal customized for the application and
end user community
–
knows how to develop a grid application in gUSE/ws-PGrade
or how to port a legacy application to the grid with gUSE/wsPGrade
Grid Portal Developer
–
He knows the Java language and JSP (Java Server Pages)
or other techniques (IceFaces etc)
–
He does not need to know the source code of gUSE
–
He and also the end users have user certificates to access
the grid
Terminology
Portal Administrator:
• installs gUSE
Grid Application Developer
• Develops a grid application with gUSE
• Exports it to the local repository of gUSE
Grid Portal Developer
•Develops an interface (in general a portlet) that fits to the
application I/O pattern and the end users’ needs and
associate it with the role
• Connects the GUI to gUSE using the programming API of
Application Specific Module(ASM)
End Users
• execute a copy of the exported application with custom
input parameters
Basic idea
• A new module called “Application Specific Module” has been developed
for gUSE that ease the creation of Application Specified Portlets
– The module provides programming API to control applications
developed using gUSE
– The module provides programming API to access inner gUSE services
• Any kind of Graphical interface can be developed on top of this module
– GUI written in JSP, JSTL (Java Servlet Tag Library ) and Java
– GUI can be customized for the grid application
– GUI can be customized for end users

Then the Grid Portal Developer creates a new web-application (mainly an web-interface) which
fits to the user community's needs, and connects it to the gUSE using ASM API

Questions?
Knowledge about JAVA+web-technologies are
needed for followings!
Otherwise: feel free to have longer coffee-break and
discussion
