1. 6. 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

3. 7. On the Performance Analysis of Large Scale, Dynamic, Distributed and Parallel Systems

   Författare :John Ardelius; Seif Haridi; Supriya Krishnamurthy; Mark Jelasity; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Performance analysis distributed systems; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Evaluating the performance of large distributed applications is an important and non-trivial task. With the onset of Internet wide applications there is an increasing need to quantify reliability, dependability and performance of these systems, both as a guide in system design as well as a means to understand the fundamental properties of large-scale distributed systems.

4. 8. 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

5. 9. Scaling Distributed Hierarchical File Systems Using NewSQL Databases

   Författare :Salman Niazi; Jim Dowling; Seif Haridi; Seif Haridi; Rui Oliveira; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : For many years, researchers have investigated the use of database technology to manage file system metadata, with the goal of providing extensible typed metadata and support for fast, rich metadata search. However, earlier attempts failed mainly due to the reduced performance introduced by adding database operations to the file system’s critical path. LÄS MER

7. 10. Resource, Data and Application Management for Cloud Federations and Multi-Clouds

   Författare :Vamis Xhagjika; Leandro Navarro Moldes; Vladimir Vlassov; Gregory Chockler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Cloud; Geo-Distribution; Live Streaming; Locality optimisation; Multicast; Multi-Cloud Overlay; Cloud Federation; Web Real-time Communications; WebRTC-RTCWEB; Media Quality; Computer Science; Datalogi;

   Sammanfattning : Distributed Real-Time Media Processing refers to classes of highly distributed, delay no-tolerant applications that account for the majority of the data traffic generated in the world today. Real-Time audio/video conferencing and live content streaming are of particular research interests as technology forecasts predict video traffic surpassing every other type of data traffic in the world in the near future.
