The Grid Checkpoint Recovery Working Group is defining a user-level API and associated layer of services that will permit checkpointed jobs to be recovered and continued on the same or on remote Grid resources.

A key feature of Grid Checkpoint Recovery service is recoverability of jobs among heterogeneous Grid resources. In other words, resources on which jobs are checkpointed need not be of the same type as those on which the jobs are recovered, as long as the application code operating on the checkpointing resource can be built for and run on the recovery platforms. The benefits of a resource-independent checkpoint recovery capability for Grids include facilitation of strategic or tactical job preemption and migration (e.g. job load balancing among available resources, cost-based job migration, etc.), in addition to recoverability of Grid-managed computational jobs across heterogeneous resources.
