“…[22] has studied the exponential, Weibull, and Gamma models of disk lifetime distributions and concluded that exponential distributions are sufficient. The failure distribution of a cluster node, which incorporates both hardware and software failures, can also be reasonably modeled as exponential distribution [61,54]. This assumption might not be realistic in some situations, such as power surges, burst of I/O tasks, etc.…”

The vulnerability of computer nodes due to component failures is a critical issue for cluster-based file systems. This paper studies the development and deployment of mirroring in cluster-based parallel virtual file systems to provide fault tolerance and analyzes the tradeoffs between the performance and the reliability in the mirroring scheme. It presents the design and implementation of CEFT, a scalable RAID-10 style file system based on PVFS, and proposes four novel mirroring protocols depending on whether the mirroring operations are server-driven or client-driven, whether they are asynchronous or synchronous. The comparisons of their write performances, measured in a real cluster, and their reliability and availability, obtained through analytical modeling, show that these protocols strike different tradeoffs between the reliability and performance. Protocols with higher peak write performance are less reliable than those with lower peak write performance, and vice versa. A hybrid protocol is proposed to optimize this tradeoff.

“…or dependability requirements such as availability or maintainability. For that, a few researchers including Friedman and Tran [1] and Welke et al [2] tried to develop a combined reliability model for the whole system including both h/w and s/w. Lie et al [3] developed a model for availability analysis of distributed s/w and h/w components.…”

“…However they all model the reliability of systems rather than that of applications to predict the failure rates of the systems. For instance, Thanakornworakij et al [19] provide a model for HPC systems while Welke et al [22] establish generic models based on Markov modelling that are applicable for hardware or software systems having wellknown architectures such as simplex and triplex modular redundant architectures. However, none of these models can be utilized to achieve application-level reliability with selective redundancy under the failure rates of both SDCs and fail-stop errors.…”

Abstract-Fail-stop errors and Silent Data Corruptions (SDCs) are the most common failure modes for High Performance Computing (HPC) applications. There are studies that address fail-stop errors and studies that address SDCs. However few studies address both types of errors together. In this paper we propose a software-based selective replication technique for HPC applications for both fail-stop errors and SDCs. Since complete replication of applications can be costly in terms of resources, we develop a runtime-based technique for selective replication. Selective replication provides an opportunity to meet HPC reliability targets while decreasing resource costs. Our technique is low-overhead, automatic and completely transparent to the user.
