CPI: A Novel Three-Phase Algorithm for QoS-Aware Replica Placement Problem [chapter]

Wei Fu, Yingjie Zhao, Nong Xiao, Xicheng Lu
2008 Lecture Notes in Computer Science  
In this paper, a novel three-phase algorithm, namely CPI, is proposed.  ...  By dividing candidate nodes into proper medium-scale partitions, CPI is capable to handle with large-scale QoS-aware replica placement problem.  ...  In order to overcome the difficulty, a novel three-phase algorithm CPI is presented to solve large-scale QoS-aware replica placement problem.  ...

A Dynamic Pressure-Aware Associative Placement Strategy for Large Scale Chip Multiprocessors

Mohammad Hammoud, Sangyeun Cho, Rami Melhem
2010 IEEE computer architecture letters  
This paper describes Cache Equalizer (CE), a novel distributed cache management scheme for large scale chip multiprocessors (CMPs). Our work is motivated by large asymmetry in cache sets usages.  ...  Temporal pressure at the on-chip last-level cache, is continuously collected at a group (comprised of cache sets) granularity, and periodically recorded at the memory controller to guide the placement  ...  We propose cache equalizer (CE), a novel mechanism that combines pressure-aware placement and smart location strategies.  ...
