Replica management is basic and challenging issue for distributed storage system designer. The objective of this paper is to dynamically create, migrate and delete replicas among nodes in response to changes in the access patterns. This paper presents an Adaptive Replica Management Model for large-scale Object-based Storage Devices (OSDs). The model expresses availability and consistency mainte...

We consider the complexity of a single-sided AdS black hole as modelled by an end-of-the-world brane. In addition, we present multi-boundary partition functions and matter correlation for such setting. compute using modified replica trick corresponding to "quenched geodesic length" in JT gravity. The late-time behaviour shows saturation constant value order $e^{S_0}$ following period linear gro...

The Eternal system provides transparent fault tolerance for CORBA applications, without requiring the modification of either the application or the ORB. Eternal replicates the application objects, and ensures strong replica consistency by employing a reliable totally-ordered multicast protocol for conveying the IIOP messages of the application. To achieve strong replica consistency during recov...

This paper proposes MUREX, a mutable replica control scheme, to keep one-copy equivalence for synchronous replication in structured P2P storage systems. For synchronous replication in P2P networks, it is proper to adopt crash-recovery as the fault model; that is, nodes are fail-stop and can recover and rejoin the system after synchronizing their state with other active nodes. In addition to the...

Restoring and non-restoring divider has become widely applicability in the era of digital computing application due to its computation speed. In this paper, we have proposed the design of divider of different architecture for the computation of Vedic sutra based. The design of divider in the Vedic mode results in high computation throughput due to its replica architecture, where latency is mini...

Data Grid is a geographically distributed environment that deals with data intensive application in scientific and enterprise computing. Data replication is a common method used to achieve efficient and fault-tolerant data access in Grids. In this paper, a dynamic data replication strategy, called Enhanced Latest Access Largest Weight (ELALW) is proposed. This strategy is an enhanced version of...

Parallel tempering (PT), also known as replica exchange, is a powerful Markov Chain Monte Carlo sampling approach, which aims at reducing the relaxation time in simulations of physical systems. In this paper, we present a novel decentralized parallel implementation of PT using the message passing interface (MPI) and the scalable parallel random number generators (SPRNG) library. By taking advan...
