1. 6. Towards Low-Complexity Scalable Shared-Memory Architectures

   Författare :Håkan Zeffer; Erik Hagersten; John Carter; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shared memory; distributed shared memory; hardware-software trade-off; software coherence; coherence profiling; remote access cache; chip multiprocessor; simultaneous multi threading; simulation; workload characterization; statistical cache model; Computer engineering; Datorteknik;

   Sammanfattning : Plentiful research has addressed low-complexity software-based shared-memory systems since the idea was first introduced more than two decades ago. However, software-coherent systems have not been very successful in the commercial marketplace. We believe there are two main reasons for this: lack of performance and/or lack of binary compatibility. LÄS MER

3. 7. Accelerating Distributed Storage in Heterogeneous Settings

   Författare :Waleed Reda; Dejan Kostic; Peter Van Roy; Marco Chiesa; Adam Morrison; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed storage; File systems; Hardware offload; Persistent memory; Distribuerad lagring; Dilsystem; Maskinvaruavlastning; Beständigt minne; Computer Science; Datalogi;

   Sammanfattning : Heterogeneity in cloud environments is a fact of life—from workload skews and network path changes, to the diversity of server hardware components, these are all factors that impact the performance of distributed storage. In this dissertation, we identify that heterogeneity can in fact be one of the primary causes of service degradation for storage systems. LÄS MER

4. 8. On performance limitations of large-scale networks with distributed feedback control

   Författare :Emma Tegling; Henrik Sandberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. LÄS MER

5. 9. Distributed File System Metadata and its Applications

   Författare :Mahmoud Ismail; Jim Dowling; Seif Haridi; Luis Veiga; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Distributed hierarchical file systems typically decouple the storage and serving of the file metadata from the file contents (file system blocks) to enable the file system to scale to store more data and support higher throughput. We designed HopsFS to take the scalability of the file system one step further by also decoupling the storage and serving of the file system metadata. LÄS MER

7. 10. Architecture Support and Scalability Analysis of Memory Consistency Models in Network-on-Chip based Systems

   Författare :Abdul Naeem; Axel Jantsch; Zhonghai Lu; Jari Nurmi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory consistency; Protected release consistency; Distributed shared memory; Network-on-Chip; Scalability;

   Sammanfattning : The shared memory systems should support parallelization at the computation (multi-core), communication (Network-on-Chip, NoC) and memory architecture levels to exploit the potential performance benefits. These parallel systems supporting shared memory abstraction both in the general purpose and application specific domains are confronting the critical issue of memory consistency. LÄS MER
