Abstract

One of the low-level services Grids can benefit from is checkpointing. Unfortunately, the checkpointing technology imposes many common problems that are still open. The example of such often-encountered problems is recovering the identifiers of some checkpointed resources. This paper describes the idea of low-level virtualization of such identifiers. The mechanism allows overcoming the semantically imposed limitations.
