Ant colony based constrained workflow scheduling for heterogeneous computing systems

The problem of constrained workflow scheduling on heterogeneous computing systems has been of major interest in the recent years. The user requirements are described by defining constraints on the workflow makespan and/or its execution cost. The uncertainty in the activity execution path and the dynamicity in the resource workload may cause some run-time changes of the makespan or cost. To prohibit runtime constraint violation, the system needs robust schedules. In this paper, probability of violation (POV) of constraints is proposed as a criterion for the schedule robustness. An ant colony system is then used to minimize an aggregation of violation of constraints and the POV. Simulation results on real world workflows show the effectiveness of the proposed method in finding feasible schedules. The results also indicate that the proposed method decreases the POV, as well as the expected penalty at run-time.

“…A KPI is introduced as significant assessing criteria for system performance under a specific domain [22] [24] that may be referred by an absolute or relative value. For the purpose of this evaluation the following KPIs were addressed: total measurements and single entries for data aggregation; computational load, time delay and success rate for system applications performance.…”

“…Unlike the related work, the insulin pump device is discarded as the patient himself is the booster of the treatment (according to doctor's guidelines). The presented SOA is based on internet protocol communication which merges different operative systems and software environments (Windows Mobile, iOS, Apache Tomcat and .NET) and is evaluated using existing KPIs under specific domains [22]. Clinical and usability assessments are out of the scope of this research work.…”
