Novel Approaches for Scheduling in D-Grid – Towards an interoperable Scheduling Framework
نویسندگان
چکیده
As the Grid is becoming the day-to-day infrastructure for e-Science and e-Business, support is required for more complex and demanding application scenarios in which not just a single resource is required, but a set of resources with certain dependencies. Such workflows complicate the management of resources, especially in cases where they are offered by several different resource providers, since resource access must be synchronised in advance to allow reliable workflow execution. In this paper we show the different Grid scheduling solutions which exist in the D-Grid ecosystem and describe in detail a workflow-aware D-Grid self-development and another, complementary, German scheduling solution. Based on the functional characteristics of these systems we identify existing gaps and show potential solutions towards an interoperable scheduling framework in the D-Grid environment. This research work is carried out under the FP6 Network of Excellence CoreGRID funded by the European Commission (Contract IST-2002004265).

As an effective means of displacing fossil fuel consumption and reducing greenhouse gas emissions, plug-in electric vehicles (PEVs) and plug-in hybrid electric vehicles (PHEVs) have attracted more and more attentions. From the power grid perspective, PHEVs and PEVs equipped with batteries can also be used as energy storage facilities, due to the fact that, these vehicles are parked most of the ...
متن کاملA New Job Scheduling in Data Grid Environment Based on Data and Computational Resource Availability
Data Grid is an infrastructure that controls huge amount of data files, and provides intensive computational resources across geographically distributed collaboration. The heterogeneity and geographic dispersion of grid resources and applications place some complex problems such as job scheduling. Most existing scheduling algorithms in Grids only focus on one kind of Grid jobs which can be data...
متن کاملTechnical Note: An opportunity cost maintenance scheduling framework for a fleet of ships: A case study
The conventional method towards deriving schedule for a fleet of ships to minimize cost alone has the short-coming of not addressing the problem of operation revenue losses associated with delays during maintenance at ships dockyards. In this paper, a preventive maintenance schedule for a fleet of ships that incorporates op-portunity cost is presented. The idea is to assign a penalty cost to al...
متن کاملTaxonomies of the Multi-criteria Grid Workflow Scheduling Problem
The workflow scheduling problem which is considered difficult on the Grid becomes even more challenging when multiple scheduling criteria are used for optimization. The existing approaches can address only certain variants of the multi-criteria workflow scheduling problem, usually considering up to two contradicting criteria being scheduled in some specific Grid environments. A comprehensive de...
