4/9/ 2000 I Datagrid Workshop- Marseille C.Vistoli Application Grid Requirements The GRID requirements are: Resource Broker to select, find and allocate the computing resources where the jobs have to be submitted. move the input files in the selected farm and submit the jobs collect the output files produced in each farm in a central repository

4/9/ 2000 I Datagrid Workshop- Marseille C.Vistoli Work needed GRAM: to provide all the necessary info to the Grid Information System Collaboration with Globus team on-going: Massimo Sgaravatto presented Need to define “what” is the necessary info in PC cluster resource environment Collaboration with WP£ GRAM/job manager persistent and fault tolerant Massimo Sgaravatto presentation Collaboration with WP3/WP4 Export the information about computing systems availability, disk and network from the LDAP server to the Class-ad collection

4/9/ 2000 I Datagrid Workshop- Marseille C.Vistoli Work needed - cont Master implements job policy and monitor the job execution. A real possibility to verify if match-making algorithm satisfy application requirements. Master access Class-ads collection to select the GRAM resource Input files are moved to the selected resource using ‘gsiftp’ using third part transfer. Input files are for this use-case small, no need for advance network reservation

4/9/ 2000 I Datagrid Workshop- Marseille C.Vistoli Work needed - cont To complete the application execution: Output files have to be collected in the central repository Data Mover and Replica Manager are useful tools. Strict collaboration with WP2 Investigate the use of advance network reservation for these files transfer: GARA
