This paper proposes an effective replica-aware scheduling algorithm for independent jobs in Grid and distributed systems. The proposed algorithm considers not only the execution time of jobs but also the location and transfer time of data and data replica that these jobs require. We propose a cost model to estimate the starting time and earliest completion time of a job and its associated data ...

Replica consistency maintenance plays a key role to improve the efficiency of replica management. This paper proposed one P2P Replica-tree based consistency maintenance strategy. In this strategy, social capacity is adopted for description of replica clustering coefficient, and one replica-tree is formed by dividing replica nodes into multi-levels. Especially peer-to-peer network with first-cla...

The Industry 4.0 concept of a Digital Twin will bring many advantages for wind energy conversion systems, e.g., in condition monitoring, predictive maintenance and the optimisation control or design parameters. A virtual replica is at heart digital twin. To construct replica, appropriate modelling techniques must be selected turbine components. These models chosen with intended use case twin mi...

The large-system performance of maximum-a-posterior estimation is studied considering a general distortion function when the observation vector is received through a linear system with additive white Gaussian noise. The analysis considers the system matrix to be chosen from a large class of random ensembles. We take a statistical mechanical approach by introducing a spin glass corresponding to ...

Replica exchange molecular dynamics is a multicanonical simulation technique commonly used to enhance the sampling of solvated biomolecules on rugged free energy landscapes. While replica exchange is relatively easy to implement, there are many unanswered questions about how to use this technique most efficiently, especially because it is frequently the case in practice that replica exchange si...

The statistical mechanics of a two-state Ising spin-glass model with finite random connectivity, in which each site is connected to a finite number of other sites, is extended in this work within the replica technique to study the phase transitions in the three-state Ghatak-Sherrington (or random Blume-Capel) model of a spin glass with a crystal-field term. The replica symmetry ansatz for the o...

This paper studies performance and timing failure probability of time-shifted redundant circuits and path-/circuit-replica circuits. Measurement-based experiments using a fabricated test chip are performed. For an approximately similar false positive error probability for the path-replica and circuit-replica, the false negative error probability of the circuit-replica is approximately two order...

In a push-based system, updates that are made to objects are sent to clients, without them explicitly requesting these updates. The focus of this research is to develop a server replication protocol for such interactive, push-based networks. When a server gets overwhelmed and is serving more clients than it can handle, a replica is created. After the replication, a portion of the clients connec...
