Overview

Cohesion is the first of a new kind of modular Peer-to-Peer multi-application Öffnet einen internen Link im aktuellen FensterDesktop Grid computing platforms. By implementing the Öffnet einen internen Link im aktuellen Fenstermicrokernel architectural pattern, Cohesion is especially suited for extension and customization even at the system level and thus can satisfy a wide variety of application-specific requirements.

Irregularly Structured Problems (ISPs)

Cohesion strives for pushing the limits of the Desktop Grid approach by enabling advanced parallel programming models. We focus on task-parallel programming models targeted towards Irregularly Structured Problems (ISPs). ISPs are parallel applications, whose computation and interaction patterns are input-dependent, unstructured and evolving during the computation. Prominent examples are discrete optimization, Opens internal link in current windowSAT Solving and constraint satisfaction problems in general. The client/server model supported by many existing Desktop Grid Computing platforms is too restricted to efficiently parallelize ISPs, since the centralized server becomes a sequential bottleneck for large numbers of clients. Thus, Cohesion provides a Opens internal link in current windowDistributed Task Pool leveraging the Peer-to-Peer operational model of Cohesion
