A path selection based algorithm for maximizing self-satisfiability of requests in real-time Grid applications
Eltayeb, Mohammed S.; Doğan, Atakan; Özgüner, Füsun (Springer-Verlag Berlin, 2004)Efficient data scheduling in Grid environments is becoming a seemingly important issue for distributed real-time applications that produce and process huge datasets. Thus, in this paper, we consider the data scheduling ... -
A path selection-based algorithm for real-time data staging in Grid applications
Eltayeb, Mohammed S.; Doğan, Atakan; Özgüner, Füsun (Academic Press Inc Elsevier Science, 2005)Efficient data scheduling is becoming an important issue in distributed real-time applications that produce huge data sets. The Grid environment on which these applications may run seeks to harness the geographically ... -
Performance of file replication policies for real-time file access in data grids
Doğan, Atakan (Association for Computing Machinery, Inc, 2007)A variety of file replication and replacement algorithms were proposed for the Data Grids in the literature. On the other hand, real-time Grid applications are emerging in many disciplines of science and engineering. Thus, ... -
Performance of real-time data scheduling heuristics under data replacement policies and access patterns in data grids
Doğan, Atakan (Springer-Verlag Berlin, 2006)A variety of real-time data scheduling heuristics were proposed for distributed, data intensive real-time applications running on a distributed computing system. The proposed heuristics are used to produce real-time data ... -
A Real-Time Data Grid Model With Centralized Job Scheduling
Atanak, Mustafa Mujdat; Tandoğan, Safai; Doğan, Atakan (Eurosis, 2010)A variety of simulators, emulators and real world infrastructures are implemented for Data Grids in the literature. Each of these works defines its own set of services and models. Yet, in the literature, there is no such ... -
Reliable matching and scheduling of precedence-constrained tasks in heterogeneous distributed computing
Doğan, Atakan; Özgüner, Füsun (Institute of Electrical and Electronics Engineers Inc., 2000)In this paper, two cost functions that can be incorporated into a matching and scheduling algorithm for tasks with precedence constraints are introduced to enable the algorithm to consider the reliability of different ... -
Scheduling of a meta-task with QoS requirements in heterogeneous computing systems
Doğan, Atakan; Özgüner, Füsun (Academic Press Inc Elsevier Science, 2006)Due to the development of new applications and the increasing number of users with diverse needs who are exposed to heterogeneous computing (HQ, providing users with quality of service (QoS) guarantees while executing ... -
Simulation of hierarchical real-time task scheduling algorithms using DGridSim
Atanak, Mustafa Mujdat; Tandoğan, Safai; Doğan, Atakan (ICST, 2010)Real-time Data Grid applications are emerging in many disciplines of science and engineering. In order to run these applications while meeting the real-time constraints associated with them, the Data Grid infrastructure ... -
Static mapping heuristics for tasks with hard deadlines in real-time heterogeneous systems
Golconda, KS; Doğan, Atakan; Özgüner, Füsun (Springer-Verlag Berlin, 2004)Hard real-time tasks are associated with strict deadlines. Classical scheduling heuristics ensure fairness among tasks and prevent deadlock, but are not concerned with deadline compliance. Hence, there is a need for ... -
Stochastic scheduling of a meta-task in heterogeneous distributed computing
Doğan, Atakan; Özgüner, Füsun (Institute of Electrical and Electronics Engineers Inc., 2001)The fact that the scheduling problem is NP-complete has motivated the development of many heuristic scheduling algorithms. These heuristic algorithms often neglect the stochastic nature of tasks' execution times. Contrary ... -
A study on performance of dynamic file replication algorithms for real-time file access in Data Grids
Doğan, Atakan (Elsevier Science BV, 2009)Real-time Grid applications are emerging in many disciplines of science and engineering. In order to run these applications while meeting the associated real-time constraints with them, the Grid infrastructure should be ... -
