Resources Virtualization in Fault-Tolerance and Migration Issues

Abstract

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 oftenencountered 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.
