The Cost of Uncore in Throughput-Oriented Many-Core Processors
Achieving performance through traditional techniques such as extracting more instruction level parallelism or increasing clock frequencies are losing their effectiveness due to the power wall. Multi-core processors have been put forth as a more power-performance efficient means of continuing performance scaling while coping with the realities of a power-limited design. Extrapolating the increas...
متن کاملGPGPU Performance Estimation with Core and Memory Frequency Scaling
Graphics Processing Units (GPUs) support dynamic voltage and frequency scaling (DVFS) in order to balance computational performance and energy consumption. However there still lacks simple and accurate performance estimation of a given GPU kernel under different frequency settings on real hardware, which is important to decide best frequency configuration for energy saving. This paper reveals a...
متن کاملDynamic Voltage-Frequency and Workload Joint Scaling Power Management for Energy Harvesting Multi-Core WSN Node SoC
This paper proposes a scheduling and power management solution for energy harvesting heterogeneous multi-core WSN node SoC such that the system continues to operate perennially and uses the harvested energy efficiently. The solution consists of a heterogeneous multi-core system oriented task scheduling algorithm and a low-complexity dynamic workload scaling and configuration optimization algori...
متن کاملData Movement and Workload characterization: Intel Sandy Bridge Core and Uncore PMU features
This paper provides a detailed on-chip and off-chip data traffic analysis on Intel Sandy Bridge microarchitecture and does workload characterization on a wide spectrum of benchmarks. The paper specifically utilizes the uncore hardware performance counters to generate memory access profile of the evaluated benchmarks. The paper presents a performance comparison across the benchmarks for multi-th...
متن کاملSpace-shared and frequency scaling based task scheduler for many- core OS
It is predicted that within the next decade chips with several 100s or 1000s of processor cores will be possible to build and will become available [1]. However, efficient usage of many-core chips will have to overcome the limits imposed by Amdahl’s law ([3], [4]). In this paper we introduce a novel task scheduling method for chip multi-processors with at least several tens, but scaling up to t...
