DPCS Solution Search Workload Management System with scheduler File transfer mechanism (data management) Proximity considerations, cost (in time) of datatransfer during scheduling Wait for local job to finish, instead of using a far node Distributed job submission Job priorities Support for Enterprise Grid A standardized API for job submission desirable Possibility to immediate re-claim of a node for localhigh priority processing (e.g. NRT) Support for heterogeneous platforms Support for up to 1000 processing node
DPCS Solution Condor Focus on computational intensive applications Supports network of clusters (departmental grid) Nodes are only registered to the local cluster master Requests are routed via master “Flocking” mechanism Jobs can be moved to other scheduler instances Automatic when there is local saturation Supports dual use nodes No job scheduling on nodes that are busy otherwise (byPFM itself) Node preemption with priority to PFM self managed nodes
