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 ... -
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 ... -
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 ... -
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 ...
