2. 11. High Performance Hybrid Memory Systems with 3D-stacked DRAM

   Author : Evangelos Vasilakis; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid memory systems; DRAM caches; Data migration; 3D-stacked DRAM;

   Abstract : The bandwidth of traditional DRAM is pin limited and so does not scale well with the increasing demand of data intensive workloads limiting performance. 3D-stacked DRAM can alleviate this problem providing substantially higher bandwidth to a processor chip. READ MORE

4. 12. Sources of Variations in Error Sensitivity of Computer Systems

   Author : Fatemeh Ayatolahi; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; error sensitivity; compiler optimization; transient fault; bit flipping; fault tolerance; fault injection;

   Abstract : Technology scaling is reducing the reliability of integrated circuits. This makes it important to provide computers with mechanisms that can detect and correct hardware errors. This thesis deals with the problem of assessing the hardware error sensitivity of computer systems. READ MORE

5. 13. Clustering in the Big Data Era: methods for efficient approximation, distribution, and parallelization

   Author : Amir Keramatian; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clustering; Approximation-based synopsis; Distributed and Parallel Processing; Applied ML;

   Abstract : Data clustering is an unsupervised machine learning task whose objective is to group together similar items. As a versatile data mining tool, data clustering has numerous applications, such as object detection and localization using data from 3D laser-based sensors, finding popular routes using geolocation data, and finding similar patterns of electricity consumption using smart meters.

6. 14. Shared Resources in Distributed Systems: Analytical Tools for Evaluation and Self-stabilizing Provisioning

   Author : Iosif Salem; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-stabilization; smart grid; online algorithms; shared object systems; resource sharing; software-defined networks; distributed algorithms;

   Abstract : Distributed computing is an established computing paradigm of modern computing systems.The nodes of a distributed system interact either by sharing resources or via a communication network. In both cases, provisioning of shared resources is a challenge, for example when resource demand and supply varies or when the system is prone to failures. READ MORE

7. 15. Symbolic Supervisory Control of Resource Allocation Systems

   Author : Zhennan Fei; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource Allocation System; Binary Decision Diagram.; Discrete Event System; Supervisory Control Theory;

   Abstract : Supervisory control theory (SCT) is a formal model-based methodology for verification and synthesis of supervisors for discrete event systems (DES). The main goal is to guarantee that the closed-loop system fulfills given specifications. SCT has great promise to assist engineers with the generation of reliable control functions. READ MORE
