Fig. 12. Workflow with application scenarios from the GEXI case studies.
The tests done for proof of concept have been in development stage. A more suitable solution
has now been created on a generic envelope base. An end-user public client application
may be implemented via a browser plugin, based on appropriate services. The current
solution is based on CEN files containing XML structures for handling and embedding data
and information. This is so important because even in standard cases we easily have to
handle hundreds of thousands of compute request from these components. In the easiest
case it will be static information from information databases, for advanced cases it is for
example conditional processing and simulation for thousands of objects like multimedia data
or borehole depth profiling.
9.9 Integrated components in practice
When taking a look onto different batch and scheduling environments one can see large
differences in capabilities, handling different environments and architectures. In the last years
experiences have been gained in handling simple features for different environments for High
Throughput Computing like Condor (Condor, 2010), workload schedulers like LoadLeveler
(IBM, 2005) and Grid Engine (SGE, 2010), and batch system environments like Moab / Torque
(Moab, 2010; Torque, 2010). Batch and interactive features are integrated with Active Source
event management (Rückemann, 2001). Listing 9 shows a small example of a CEN embedded
into an Active Source component.
