System-Level Versus User-Defined Checkpointing

Checkpointing and rollback recovery is a very effective technique to tolerate transient faults and preventive shutdowns. In the past, most of the checkpointing schemes published in the literature were supposed to be transparent to the application programmer and implemented at the operating-system level. In the recent years, there has been some work on higher-level forms of checkpointing. In this second approach, the user is responsible for the checkpoint placement and is required to specify the checkpoint contents. In this paper, we compare the two approaches: systemlevel and user-defined checkpointing. We discuss the pros and cons of both approaches and we present an experimental study that was conducted on a commercial parallel machine.
