Consistency Models in Distributed Systems with Physical Clocks

Jiaqing Du

Most existing distributed systems use logical clocks to order events in the implementation of various consistency models. Although logical clocks are straightforward to implement and maintain, they may affect the scalability, availability, and latency of t ...

Integrating Rate Based Models into a Multi-Objective Process Design & Optimisation Framework using Surrogate Models

Levent Sinan Teske

In the development of energy and chemical processes, the process engineers extensively apply computer aided methods to design & optimise these processes and corresponding process units. Such applications are multi-scale modelling and multi-objective optimi ...

Preventive reactive power management for improving voltage stability margin

Sidi-Rachid Cherkaoui, Mokhtar Bozorg, Omid Alizadeh Mousavi

Voltage stability imposes important limitations on the power systems operation. Adequate voltage stability margin needs to be obtained through the appropriate scheduling of the reactive power resources. The main countermeasures against voltage instability ...

Clock-SI: Snapshot Isolation for Partitioned Data Stores Using Loosely Synchronized Clocks

Willy Zwaenepoel, Sameh Mohamed Elnikety, Jiaqing Du

Clock-SI is a fully distributed protocol that implements snapshot isolation (SI) for partitioned data stores. It derives snapshot and commit timestamps from loosely synchronized clocks, rather than from a centralized timestamp authority as used in current ...

Reactive power reserve management: Preventive countermeasure for improving voltage stability margin

Sidi-Rachid Cherkaoui, Mokhtar Bozorg, Omid Alizadeh Mousavi, Ali Ahmadi Khatir

Voltage stability imposes important limitations on the power systems operation. The system should be operated with an adequate voltage stability margin by the appropriate scheduling of reactive power resources and voltage profile. The main countermeasures ...

Two-Phase Control of On-Chip Two-Phase Cooling Systems of Servers

John Richard Thome, Jackson Braz Marcinichen

Thermal designers of data centers and server manufacturers are showing a great concern regarding the cooling of new generation data centers, which are more compact and dissipate more power than is currently possible to cool by conventional air conditioning ...

Towards Multi-Fabric 3D Integration Architectures

Panagiotis Athanasopoulos

The main aim of this thesis is to examine the advantages of 3D stacking applied to microprocessors and related integrated microprocessor systems in the architectural level. In the succession of years microprocessors are aiming towards lower power consumpti ...

Cuckoo Directory: A Scalable Directory for Many-Core Systems

Babak Falsafi, Pejman Lotfi Kamran, Michael Ferdman

Growing core counts have highlighted the need for scalable on-chip coherence mechanisms. The increase in the number of on-chip cores exposes the energy and area costs of scaling the directories. Duplicate-tag based directories require highly associative st ...
