Grid Service Reliability Modelling and Optimal TaskScheduling Considering Fault Recovery Seminar by:Prakash Saladi Guided by: PROF. Scott Spetka
PROPOSED SYSTEM • The basic approach of fault recovery in grid systems is a Remote Node Fault Recovery (RNFR) mechanism. • when a failure occurs on a node, the state information can be migrated to another node, and the failed subtask execution is resumed from the interrupted point, or the failed subtask can be dynamically rescheduled on another node, and the node restarts the subtask from the beginning.
MODULES • The Application is split into below modules: • USERS • RESOURCE • GRID
Users: -- Connect to Grid -- Send request to grid -- Get response from Grid Resource: -- Accept request from Grid -- Process and send output to Grid
Grid: -- Maintain Users/Nodes -- Take Request from User -- Schedule task to Resource -- Accept the output from Resource -- Validate the output -- Reschedule the task (if output is invalid) -- Intimate the Grid Manager for Fault Generated -- Send output to User (if valid) -- Handle Network Failure and intimate the Grid
