Within the BIS-Grid project 3 , a BMBF-funded project in the context of the German D-Grid initiative, we developed the BIS-Grid workflow engine that is based upon service extensions to UNICORE 6 to use an arbitrary WS-BPEL workflow engine and standard WS-BPEL to orchestrate stateful, WSRF-based Grid services. Although aimed at proving the feasibility of(More)
The BIS-Grid project, as part of the German D-Grid initiative , investigates service orchestration using Grid service technologies to show how such technologies can be employed for information systems integration, especially when crossing enterprise boundaries. Small and medium enterprises will be enabled to integrate heterogeneous business information(More)
A continuous trend in computing is the demand for increasing computing performance. Provided that the problem space allows a solution that can be separated in parts to be computed independently, parallel systems offer a performance that exceeds that of sequential systems. To continue to improve processor performance, companies such as Intel and AMD have(More)
