Nowadays, energy saving has become one of the most critical issues in IT. In this paper, we propose an energy-efficient method, message classifying and voltage control (MCVC), for scheduling inter-processor communications on multi-core processors. The proposed technique has two new elements in scheduling and energy saving technologies. Firstly, the MCVC suggests a contention-free scheduling method...
Loop scheduling on parallel and distributed systems has been a critical problem. Furthermore, it becomes more difficult to deal with on the emerging heterogeneous grid environments. In the past, some loop self-scheduling schemes have been proposed to be applicable to heterogeneous gird environments. In this paper, we propose a performance-based approach, which partitions loop iterations according...
With the rapid proliferation of hardware devices, cluster computing has encountered the problem of heterogeneous resources. We have constructed a multi-cluster system that works with and without storage devices, and evaluated the system performance. We dispatch jobs with the strategy we propose to make the best use of system resources. In this paper we introduce this new scheduling system based on...
Parallel loop scheduling on grid environments is a challenging problem, especially for loops with irregular workload distribution. In the past, this problem of load imbalance resulting from irregular workload was not explicitly addressed. This paper proposes a new approach to schedule loop iterations with irregular workload on grid environments. Based on knowledge-based estimation of workload, the...
