Abstract
Solving distributed computing infrastructure (DCI) incompatibility issues in a generic way is a challenging and complex task. Gateways and workflow management systems are often tightly bound to some limited number of supported DCIs. To enable gateways access to many different DCIs and to solve DCI compatibility among the very different workflow management systems, we have developed a generic solution, the DCI Bridge. In this chapter we describe its internal architecture, provide usage scenario and show how the DCI Bridge resolves interoperability issues between various middleware-based DCIs. We also provide insight about the capabilities of the realized system. The generic DCI Bridge service seamlessly enables the execution of workflows (and jobs) on major DCI platforms such as ARC, Globus, gLite, UNICORE, SGE, PBS, as well as web services or clouds.
