TGrid - Grid runtime support for hierarchically structured task-parallel programs
Sascha Hunold, Thomas Rauber, Gudula Rünger · 2006
In this article we introduce a grid runtime system called TGrid which is designed to run hierarchically structured task-parallel programs on heterogenous environments and can also be used for common component-based grid programming. TGrid is built on top of a location-aware communication layer which enables the runtime system to cluster grid nodes. As a result, the component scheduler assigns a multi-processor task to a set of processors taking into account the spatial locality within the available processors. The multi-processor task directly benefits from having less network overhead and thus, the overall runtime of a grid-enabled multi-processor program is reduced
