OBJECTIVE As a constructive replication and extension of Arthur, Edwards, Bell, Villado, and Bennett (2005), the objective of the current study was to further investigate the efficacy of team relatedness and team workflow ratings (along with their composite) as metrics of interdependence. BACKGROUND Although an analysis of task and job interdependence has important implications and uses in do...

In this paper, we evaluate the efficacy, in a Hadoop setting, of two coding schemes, both possessing an inherent double replication of data. The two coding schemes belong to the class of regenerating and locally regenerating codes respectively, and these two classes are representative of recent advances made in designing codes for the efficient storage of data in a distributed setting. In compa...

WANG, CHAO. Transparent Fault Tolerance for Job Healing in HPC Environments. (Under the direction of Associate Professor Frank Mueller). As the number of nodes in high-performance computing environments keeps increasing, faults are becoming common place causing losses in intermediate results of HPC jobs. Furthermore, storage systems providing job input data have been shown to consistently rank ...

A Data Grid connects a collection of geographically distributed computational and storage resources that enables users to share data and other resources. Data replication, a technique much discussed by Data Grid researchers in recent years creates multiple copies of file and places them in various locations to shorten file access times. In this paper, a dynamic data replication strategy, called...

In data grids huge amount of data are generated and processed by users around the world. Objective of dynamic replica strategies is reducing file access time by reducing network traffic, which leads to reducing job runtime. In this paper a replication algorithm for a 3-level hierarchical structure and a scheduling algorithm are proposed. The simulation results with optorsim show better performa...

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...

CONTEXT The field of public health faces multiple challenges in its efforts to recruit and retain a robust workforce. Public health departments offer salaries that are lower than the private sector, and government bureaucracy can be a deterrent for those seeking to make a difference. OBJECTIVE The objective of this research was to explore the relationship between general employee satisfaction...

toxoplasmosis is a protozoal infection caused by toxoplasma gondii. toxoplasmosis produce severe damage in patients who are immunosuppresed. in those who are immunosupressed, latent infection can be reactivated resulting in acute disseminating disease. betamethasone is a synthetic glycocorticoid, used as an anti-inflamatory and immunosuppressant in a wide variety of disorders.the aim of this st...

data grids support access to widely distributed storage for large numbers of users accessing potentially many files. to enhance access time, replication at nearby sites may be used. data replication, a technique much investigated bydata grid researchers in past years creates multiple replicas offile and places them in conventional locations to shorten fileaccess times. one of the problems in da...
