Listing 11. Embedded Active Source Condor script.
With Actmap CRI being part of Active Source, calls to parallel processing interfaces, e.g., using
InfiniBand, can be used, for example MPI (Message Passing Interface) and OpenMP, already
described for standalone job scripts for this purpose, working analogical (Rückemann, 2009).
9.11 Service and operation
With the complexity of the high level integration of disciplines, services, and resources there
are various aspects that cannot be handled in general as they will depend on scenario,
collaboration partners, state of current technology, andmany other. Based on the collaboration
framework operation can integrate Service Oriented Architectures (SOA) and Resources
Oriented Architectures (ROA). Based on the pre-implementation case studies and application
scenarios it will be necessary to define agreements on the low level of services (S-Level)
and operation (O-Level). For the S-Level integrated systems will need to collect Service
Level Requests (SLR), define Service Level Specifications (SLS), and specify appropriate
Service Level Agreements (SLA). According to these, on the O-Level Operational Level
Agreements (OLA) have to be arranged. In all practical cases these agreements together
with the underlying Service Level Management (SLM) should clearly take up less than two
to five percent of the overall capacity for the collaboration for an efficient and effective
system. The most important mostly non-technical factor for planning complex integrated
systems therefore is to limit the dominance and growth of management, administrative, and
operational tasks. Economic target centred contracts can be a solution to set limits to possible
usuriousness, for example to restrict against “hydrocephalic” reporting and auditing.
10. Evaluation
The case studies demonstrated that integrated systems can be successfully implemented
with enormous potential for flexible solutions. Disciplines, services, and resources level
can be handled under one integrated concept. Interactive dynamical information systems
components have been enabled to use an efficient abstraction and to handle thousands of
subjobs for parallel processing, in demanding cases without the disadvantages of distributed
systems. With the results of the case studies we can answer one additional question: What
are the essential key factors for long-term use of integrated components? The academic and
industry partners involved in the case studies emphasised that the key factors are:
• Information, instructions, and meta data have to be self explanatory.
• Multi-lingual information need appropriate interfaces in order to be editable and
processable along with each other.
• Information has to be stored in a common non proprietary way.
• Tools for processing and interfacing the information have to be available without
restrictions.
• Component atoms need to be recyclable.
• Information and components have to be widely portable.
