An efficient algorithm for independent tasks scheduling in heterogeneous computing systems.
Masters thesis, Universiti Putra Malaysia.
Abstract
Task scheduling is critical in heterogenous systems, especially with the huge
number of tasks transmitted over grid. Since heuristics are proposing methods for
solving heterogenous computing systems, several techniques were proposed for the
scheduling on grid computing systems to get better execution time. In this thesis, a
proposed new heuristic algorithm named Two Stages TasksTransfer (TSTT)
algorithm introduced as an enhancement of state of TPB scheduling algorithm.
Scheduling problem addressed Heterogeneous Computing Scheduling Problem
(HCSP) mathematical model, where the independent tasks assigned to
heterogenous processors with different characteristics. Twelve datasets with
different heterogeneity level examined using different heuristic algorithms to
compare the performance with the new algorithm. The proposed algorithm showed
its efficiency in term of makespan, resource utilization and load balancing metrics for
set of tasks.
