Job-Arrival aware distributed run-time resource management on intel SCC manycore platform

Modern computing systems are dealing with a diverse set of complex and dynamic workloads in the presence of varying job arrival rates. This diversity is raising the need for the development of sophisticated run-Time mechanisms that efficiently manage system's resources. In addition, moving towards kilo-core processor architectures, centralized resource management approaches will most probably form a severe performance bottleneck, thus the study of Distributed Run-Time Resource Management (DRTRM) schemes is now gaining a lot of attention. In this paper, we propose a job-Arrival aware DRTRM framework for applications with malleable characteristics, implemented on top of the Intel Single-Chip Cloud Computer (SCC) many-core platform. We show that resource allocation is highly affected not only by the internal decision mechanisms but also from the incoming application interval rate on the system. Based on this observation, we propose an effective admission control strategy utilizing Voltage and Frequency Scaling (VFS) of parts of the DRTRM which eventually retains the distributed decision making thus improving system performance in combination with significant gains in its consumed energy
