Along with the increased awareness of energy cost, power management becomes a big issue for clusters. In this study, we investigate the workload aware power management techniques for cluster systems and propose a new power management policy. The considered power management techniques are dynamic workload consolidation and usage of dynamic power range enabled by low power states on servers. The power management policy has been implemented on OpenPBS with Maui, which reduces about ten percent power consumption and optimizes workload distribution to lower the impact on performance.

The performance analysis of distributedsoftwaresystems is a challenging task in which the assessment of performance measures is a vital step. Due to its versatility, the concept of software performance engineering (SPE) has been advocated as a promising solution towards realizing that step. This paper illustrates how by using our recently proposed Model-Driven SPE (MDSPE) approach, one can design annotated UML performance models for the performance analysis of distributedsoftwaresystems, based on the UML profile for Schedulability, Performance and Time. A case study of a business system is used to validate the stated goal.
This paper deals with the issue of developing efficient algorithms for accelerating SIFT (Scale Invariant Feature Transform) features extraction under distributed environment. The proposed distributed dynamic parallel...
