Dissertation title and abstract:


Title: EXPLOITING RESOURCE HETEROGENEITY ON COMPUTATIONAL GRIDS FOR ENERGY-EFFICIENT SCHEDULING

Resumo:
In recent years, researchers of the High Performance Computing (HPC) community have proposed solutions for the problem of high energy consumption in large scale distributed platforms, as the energy consumption increases proportionally to the computational power. Besides the cost of electric bills, the main problem of the high energy consumption of HPC platforms are the emissions of greenhouse gases. For this purpose, several energy-aware heuristics have been developed for scheduling applications in clusters, grids and clouds. However, performance is still required for such an application. The trade-off between energy consumption and execution time is not easy to achieve. Furthermore, resources heterogeneity is the key to improve the efficiency of energy efficient schedulers. To solve the problem of energy consumption in computational grids, we developed a new power-aware scheduling heuristic that tries to find the solutions with better trade-off between energy consumption and execution time of Bag-of-Tasks (BoT) applications in computational grids. Additionally, we evaluate and discuss the impact of resources heterogeneity over energy efficient schedulers. This evaluation helps to understand how Resource Management Systems (RMS) could contribute with energy consumption reduction by being aware of local schedulers and thus provide better resources.
