Location of Processor Allocator and Job Scheduler and Its Impact on CMP PerformanceHigh Performance Computing (HPC) architectures are being developed continually with an aim of achieving exascale capability by 2020. Processors that are being developed and used as nodes in HPC systems are Chip Multiprocessors (CMPs) with a number of cores. In this paper, we continue our effort towards a better processor allocation process. The Processor Allocator (PA) and Job Scheduler (JS) proposed and implemented in our previous works are explored in the context of its best location on the chip. We propose a system, where all locations on a chip can be analyzed, considering energy used by Network-on-Chip (NoC), PA and JS, and processing elements. We present energy models for the researched CMP components, mathematical model of the system, and experimentation system. Based on experimental results, proper placement of PA and JS on a chip can provide up to 45% NoC energy savings.

Application Specific

In this chapter, we present a reconfigurable architecture for network-on-chips (NoC) on which arbitrary application-specific topologies can be implemented. The proposed NoC can dynamically tailor its topology to the traffic pattern of different applications, aiming to address one of the main drawbacks of existing application-specific NoC optimization methods, i.e. optimizing NoCs based on the traffic pattern of a single application. Supporting multiple applications is a critical feature of an NoC as several different applications are integrated into the modern and complex multi-core system-on-chips and chip multiprocessors and an NoC that is designed to run exactly one application does not necessarily meet the design constraints of other applications. The proposed NoC supports multiple applications by configuring as a topology which matches the traffic pattern of the currently running application in the best way. In this chapter, we first introduce the proposed reconfigurable topology and then address the two problems of core to network mapping and topology exploration. Experimental results show that this architecture effectively improves the performance of NoCs and reduces power consumption.
