“…1. XtreemOS Grid-Checkpointing Architecture [9] At the grid level, a job checkpointer service is in charge of managing the checkpoint/restart of a job, possibly spanning multiple grid nodes. It is located on the same node as the job manager and uses virtual nodes [11] to achieve service replication and thus high-availability.…”

“…Therefore, in order to achieve fault tolerance for distributed applications in grids, XtreemOS [8] deploys a heterogeneous grid checkpointing service called XtreemGCP [9]. This service is designed to support different checkpointing protocols and address the underlying grid-node checkpointers in a transparent manner through a uniform interface.…”

Abstract-The EU-funded XtreemOS project implements an open-source grid operating system based on Linux. In order to provide fault tolerance and migration for grid applications, it integrates a distributed grid-checkpointing service called XtreemGCP. This service is designed to support different checkpointing protocols and to address the underlying gridnode checkpointers (e.g. BLCR, LinuxSSI, OpenVZ, etc.) in a transparent manner through a uniform interface. In this paper, we present the integration of an independent checkpointing and rollback-recovery protocol into the XtreemGCP. The solution we propose is not checkpointer bound and thus can be transparently used on top of any grid-node checkpointer.To evaluate the prototype we run it within a heterogeneous environment composed of single-PC nodes and a Single System Image (SSI) cluster. The experimental results demonstrate the capability of the XtreemGCP service to integrate different checkpointing protocols and independently checkpoint a distributed application within a heterogeneous grid environment. Moreover, the performance evaluation also shows that our solution outperforms the existing coordinated checkpointing protocol in terms of scalability.

“…Sockets must also be closed and recreated on nodes whose checkpointers are incapable of handling open socket descriptors. Both tasks can be handled using the callback mechanism provided by XtreemGCP [13]. The latter explicitly executes registered callbacks before and after a checkpoint or after a restart.…”

“…All these implementations come with different capabilities and there is no ultimate best checkpointer. Therefore, we have designed XtreemGCP -a grid checkpointing service capable of checkpointing and restarting a grid job running on nodes equipped with different checkpointing packages [13]. Each grid job consists of one or multiple job units.…”

Abstract. 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 checkpointers for distributed applications. The measurement numbers show only a small overhead especially with respect to large grid-applications where checkpointing may consume many minutes.
