Control-theoretic Thermal Balancing for Clusters
نویسندگان
چکیده
Thermal management is critical for clusters because of the increasing power consumption of modern processors, compact server architectures and growing server density in data centers. Thermal balancing mitigates hot spots in a cluster through dynamic load distribution among servers. This paper presents the Control-theoretical Thermal Balancing (CTB) algorithms that employ feedback control loops to dynamically balance the temperature of different servers. CTB features optimal controllers designed based on a difference equation model that captures thermal dynamics of clusters. Stability analysis and simulation results demonstrate that CTB can provide effective temperature balancing when servers’ power consumption and ambient temperature deviate from estimation or change significantly at run-time.

Optimality Theoretic Account of Acquisition of Consonant Clusters of English Syllables by Persian EFL Learners*
This study accounts for the acquisition of the consonant clusters of English syllable structures both in onset and coda positions by Persian EFL learners. Persian syllable structure is "CV(CC)", composed of one consonant at the initial position and two optional consonants at the final position; whereas English syllable structure is "(CCC)V(CCCC)". Therefore, Persian EFL learners need to resolve...

Identifying clusters is an important aspect of data analysis. This paper proposes a noveldata clustering algorithm to increase the clustering accuracy. A novel game theoretic self-organizingmap (NGTSOM ) and neural gas (NG) are used in combination with Competitive Hebbian Learning(CHL) to improve the quality of the map and provide a better vector quantization (VQ) for clusteringdata. Different ...
