The GridFlow project is a large collaborative project to integrate a wide range of existing grid middleware. Existing systems for resource scheduling, resource management, and performance services were integrated with the [Globus toolkit] and [MDS] Information Services. All these components are controlled from a user portal which provides simulation, execution, and monitoring functionality. Gridflow uses an XML specification to represent the workflow and offers visual editing tools. Workflows consist of subworkflows which are mapped onto local and global grid resources. Single tasks are usually MPI or PVM parallel jobs and single-task scheduling is done by Titan resource allocator. 1 Resources - {link:J.Cao, S.A.Jarvis, S.Saini, G.R.Nudd\: ~~GridFlow: Workflow Management for Grid Computing~~|http://www.ccrl-nece.de/~cao/doc/jcao_c_flow.pdf} 2004-10-08 07:32:41.982 2004-09-13 11:23:56.68
