Checkpointing and Migration of Communication Channels in Heterogeneous Grid Environments

摘要

A grid checkpointing service providing migration and transparent fault tolerance is important for distributed and parallel applications executed in heterogeneous grids. In this paper we address the challenges of checkpointing and migrating communication channels of grid applications executed on nodes equipped with different checkpointer packages. We present a solution that is transparent for the applications and the underlying checkpointers. It also allows using single node check-pointers for distributed applications. The measurement numbers show only a small overhead especially with respect to large grid-applications where checkpointing may consume many minutes.
