Security assurance is a critical requirement for QoS or SLA satisfactions in risky grid environments because jobs may be scheduled to multiple machines across different distributed administrative domains. Unlike conventional methods using fixed-number job replications, in this paper, we propose a security-aware parallel and independent job scheduling algorithm based on adaptive job replications...

In grid environment, jobs may be scheduled to multiple machines across different administrative domains. However, grid security is a main hurdle to make the job scheduling decision secure, reliable and fault tolerant. A security-aware parallel and independent job scheduling algorithm in grid computing environment based on adaptive job replications was proposed. In risky and failure-prone grids,...

Grid technology, which together a number of personal computer clusters with high speed networks, can reach the same computing power as a supercomputer does, also with a minimum cost. However, heterogeneous system is called as grid. Scheduling independent tasks on grid is more difficult. In order to utilize the power of grid completely, we demand an efficient job scheduling algorithm to execute ...

Job-related exhaustion is the core dimension of burnout, a work-related stress syndrome that has several negative health consequences. In this study, we explored the molecular genetic background of job-related exhaustion. A genome-wide analysis of job-related exhaustion was performed in the GENMETS subcohort (n = 1256) of the Finnish population-based Health 2000 study. Replication analyses incl...

In grid computing, the realization of an enviable fault tolerance ability is linked with the proper utilization of resources and scheduling of jobs. The literature offers two solutions to these two challenging tasks, viz. checkpointing and replication. A checkpointing strategy is being proposed that uses the median of failure intervals of the resources in deciding the checkpoint intervals for t...

If queue-states are unknown to a dispatcher, replication strategy has been proposed where job copies sent randomly servers. When the service of any copy is completed, redundant removed. For jobs that can be algebraically manipulated and have linear servers, get response-time performance sending d n via strategy, with Maximum Distance Separable (MDS) codes we show n+d suffice. That is, while mul...

To the existing data replication approaches, we add more dynamics about occasional data absence whereby files are replicated in advance in order to make all sites as suitable for job executions as possible. Occasional node or edge absence resulting in data absence is inevitable in wireless network environments. This approach offers several advantages to wireless grids, such as improved fault-to...

Traditional job schedulers for grid or cluster systems are responsible for assigning incoming jobs to compute nodes in such a way that some evaluative condition is met. Such systems generally take into consideration the availability of compute cycles, queue lengths, and expected job execution times, but they typically do not account directly for data staging and thus miss significant associated...
