1 European Research Network on Foundations, Software Infrastructures and Applications for large scale distributed, GRID and Peer-to-Peer Technologies {image:logo.jpg} http://www.coregrid.net/ 1.1 Grid Workflows The CoreGRID project addresses Grid workflows mainly in workpackage 5 ({link:Grid Information, Resource and Workflow Monitoring Services|http://www.coregrid.net/mambo/content/view/112/118/}) and workpackage 6 ({link:Resource Management and Scheduling|http://www.coregrid.net/mambo/content/view/113/119/}). The corresponding tasks are task 5.3 (Workflow Services) and task 6.3 (Workflow GRID Scheduling Strategies). Contact person is Andreas Hoheisel (alias [bassheide]). 1.1 Research Groups related to Grid Workflows Several research groups related to Grid Workflows have been established within CoreGRID: {table} Research Group | Task | Partners | Contact __Introducing collaborative workflows in legacy code environments.__ The aim is to extend the [P-GRADE] Portal - which is already operating as a service for several [EGEE] VOs around Europe - with a "grid testing engine". This engine should collect resource and service aviability information on a regular basis. This database can be used by grid-specific brokers or by the workflow cheduler and manager component of the [P-GRADE] Portal for intelligent decisions | 5.3 | SZTAKI, UoW | Gergely Sipos, SZTAKI __Workflow description languages using high-level Petri nets for Grid workflows__ | 5.3/6.3 | UMUE, FHG | Andreas Hoheisel, Fraunhofer FIRST ([bassheide]) __Extending the SEAGRIN semantic overlay grid infrastructure__ (a potential candidate for content-based monitoring infrastructure) with the collaborative workflow management support of the P-GRADE portal | 5.3 | SZTAKI, MU | __Compatibility and conversion of different Grid workflow description languages.__ The objective of this research group will be a joint survey about compatibility and conversion (mapping) issues between commonly available workflow description languages. (refer to [Workflow Description Languages/Compatibility and Conversion])| 5.3 | FHG, UMUE, UNICAL, --INFN-- | Andreas Hoheisel, Fraunhofer FIRST ([bassheide]) __Fault tolerance in Grid workflow execution.__ The objective of the reserch group is to elaborate the theory of fault tolerant workflow execution on top of widely used grid middleware systems, namely Globus, LCG-2 and gLite. The group members are currently using the Condor DAGMan workflow manager as a workflow enactor tool in their P-GRADE Portal and GEMLCA systems. Within Task 5.3 the group would like to implement an intelligent fault tolerant layer on top of Condor DAGMan. | 5.3 | SZTAKI (Gergley Sipos, Peter Kacsuk), UoW (Gabor Terstyanszky, Tamas Kiss) | Gergely Sipos, SZTAKI It is planned to collaboratively develop __advanced performance prediction and scheduling mechanisms on top of workflow definition language__ | 6.3 | UMUE, FHG | Martin Alt, UMUE Starting a collaboration in the topic of __workflow scheduling considering the P-GRADE Portal, KOALA and Petri-net based workflows__. Our goals are to analyse scheduling mechanisms for workflows, and how information gained from automatic workflow analysis can support and enhance scheduling. We will extend KOALA with workflow support and the P-GRADE Portal with another scheduling features | 6.3 | SZTAKI, TU Delft, UMUE | Martin Alt, UMUE Collaboration related to the __integration of the Grid Resource Management System [GRMS] and [Triana]__ | 6.3 | Cardiff Univ, PSNC | Krzysztof Kurowski, PSNC {table} 1.1 References {table} Publication | Partner A.
