Biobjective scheduling algorithms for execution time-reliability trade-off in heterogeneous computing systems
Doğan, Atakan; Özgüner, Füsun (Oxford University Press, 2005)A heterogeneous computing (HC) system is composed of a suite of geographically distributed high-performance machines interconnected by a high-speed network, thereby providing high-speed execution of computationally intensive ... -
A comparison of static QoS-based scheduling heuristics for a meta-task with multiple QoS dimensions in heterogeneous computing
Golconda, K. S.; Özgüner, Füsun; Doğan, Atakan (2004)The problem of scheduling a set of independent tasks (a meta-task) with multiple QoS needs, such as Timeliness, Reliability, Versions, Security and Priority, in a Heterogeneous Computing (HC) environment is referred to as ... -
Concurrent scheduling: Efficient heuristics for online large-scale data transfers in distributed real-time environments
Eltayeb, Mohammed S.; Doğan, Atakan; Özgüner, Füsun (IEEE Computer Soc, 2006)The static staging heuristics proposed in the literature for staging the data items associated with real-time distributed applications adhere to a method by which only one data item is transferred in each communication ... -
A data scheduling algorithm for autonomous distributed real-time applications in grid computing
Large-scale data intensive applications with real-time requirements are currently emerging in many disciplines of science and engineering. Such applications can benefit from a Grid environment provided that an efficient ... -
Evaluation of intersection collision warning system using an inter-vehicle communication simulator
Doğan, Atakan; Korkmaz, G.; Liu, Y.; Özgüner, Füsun; Redmill, K.; Tokuda, K. (2004)An inter-vehicle communication (IVC) simulator has been developed to evaluate an intersection collision warning system. Various representative intersection collision scenarios are simulated.

Extended partial path heuristic for real-time staging in oversubscribed networks
Eltayeb, Mohammed S.; Doğan, Atakan; Özgüner, Füsun (Springer-Verlag Berlin, 2003)In this paper we propose the use of the PPH as a base for an offline schedule method to detect unsatisfiable requests in a staging system. This property allows a reduction in the overhead of transferring data-items with ... -
On QoS-based scheduling of a meta-task with multiple QoS demands in heterogeneous computing
Doğan, Atakan; Özgüner, Füsun (Institute of Electrical and Electronics Engineers Inc., 2002)This paper investigates the problem of scheduling a set of independent tasks with multiple QoS needs, which may include timeliness, reliability, security, data accuracy, and priority, in a heterogeneous computing system. ... -
Optimal and suboptimal reliable scheduling of precedence-constrained tasks in heterogeneous distributed computing
Doğan, Atakan; Özgüner, Füsun (Institute of Electrical and Electronics Engineers Inc., 2000)This paper introduces algorithms which can produce both optimal and suboptimal task assignments to minimize the probability of failure of an application executing on a heterogeneous distributed computing system. A cost ... -
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 ... -
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 ... -
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 ... -
Stochastic scheduling of data for minimizing execution time of SPMD applications
Doğan, Atakan; Özgüner, Füsun (Int Inst Informatics & Systemics, 2003)This paper introduces a static load balancing algorithm for SPMD type of applications executing on a shared heterogeneous computing system. This novel algorithm is motivated from the fact that the mean values of the computing ... -
Trading off execution time for reliability in scheduling precedence-constrained tasks in heterogeneous computing
Doğan, Atakan; Özgüner, Füsun (Institute of Electrical and Electronics Engineers Inc., 2001)This paper investigates the problem of matching and scheduling of an application, which is composed of tasks with precedence constraints, to minimize both execution time and probability of failure of the application in a ...
