“…In [10] we have evaluated the coordinated checkpointing protocol using a similar client-server application within a heterogeneous environment consisting of single PC-nodes and an SSI cluster. Therefore, we have measured the time it takes to checkpoint this application when it opens up 50 communications channels and sends 100 Byte packets periodically every five seconds.…”

Given a grid environment where data and computing resources of one application can be distributed across thousands of grid nodes, coordinated checkpointing can be costly in terms of scalability [10].…”

Furthermore, the entire application needs to be rolled back in the event of a single process failure.…”

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.
