@article{(Open Science Index):https://publications.waset.org/pdf/8996, title = {Generic Workload Management System Using Condor-Based Pilot Factory in PanDA Framework}, author = {Po-Hsiang Chiu and Torre Wenaus}, country = {}, institution = {}, abstract = {In the current Grid environment, efficient workload management presents a significant challenge, for which there are exorbitant de facto standards encompassing resource discovery, brokerage, and data transfer, among others. In addition, the real-time resource status, essential for an optimal resource allocation strategy, is often not readily accessible. To address these issues and provide a cleaner abstraction of the Grid with the potential of generalizing into arbitrary resource-sharing environment, this paper proposes a new Condor-based pilot mechanism applied in the PanDA architecture, PanDA-PF WMS, with the goal of providing a more generic yet efficient resource allocating strategy. In this architecture, the PanDA server primarily acts as a repository of user jobs, responding to pilot requests from distributed, remote resources. Scheduling decisions are subsequently made according to the real-time resource information reported by pilots. Pilot Factory is a Condor-inspired solution for a scalable pilot dissemination and effectively functions as a resource provisioning mechanism through which the user-job server, PanDA, reaches out to the candidate resources only on demand.}, journal = {International Journal of Industrial and Manufacturing Engineering}, volume = {4}, number = {4}, year = {2010}, pages = {331 - 340}, ee = {https://publications.waset.org/pdf/8996}, url = {https://publications.waset.org/vol/40}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 40, 2010}, }
