This paper presents a comprehensive load balancing approach using priority based migration (PBM) mechanism for a trusted small scale distributed computing environment. A process migration server (PMS) that acts as a cluster management server reduces latency time in migrated process execution; leading to no starvation condition for any process thus achieving uniform distribution of load among all the...
In this paper we propose an adaptive scheduling algorithm for IEEE 802.16j based wireless broadband networks. Computation of an optimal schedule for prioritized traffic in OFDMA based IEEE 802.16 wireless network is an NP-Hard problem. Hence, we propose a scheduling heuristic for an OFDMA based WiMAX relay network. The ORS (OFDMA Relay Scheduler) heuristic computes the zone boundaries (relay and access)...
Different economic models have been applied to the resource allocation problem in grids. Contract net is one such model in which a job is announced to the resources, the resources bid for the job, and then the broker chooses one bid from the received bids based on some policy. The job is awarded to the resource with the winning bid. In this paper, we first propose a contract net based resource allocation...
Different market mechanisms have been used to match resources with users in grids. In this paper, we propose two simple contract-net based resource selection policies in grids with heterogeneous resources. A detailed experimental evaluation of the policies shows that they perform better than other commonly used policies for many scenarios.
It is important for business organizations to be adaptive so that they are able to withstand the changes in the environment like sudden increase in the task arrival rate. Flexible assignment of the number of resources to organizations is necessary for adaptation. In this paper, a technique based on Organization Self-Design (OSD) is used to achieve this objective. The basic aim is to cater to the real-time...
The SPLASH-2 suite of parallel applications has recently been released to facilitate the study of centralized and distributed shared-address-space multiprocessors. In this context, the paper has two goals. One is to quantitatively characterize the SPLASH-2 programs in terms of fundamental properties and architectural interactions that are important to understand them well. The properties we study...
