1. 11. 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.

   Sammanfattning : Autonomic computing aims at making computing systems self-managing by using autonomic managers in order to reduce obstacles caused by management complexity. This thesis presents results of research on self-management for large-scale distributed systems. LÄS MER

4. 13. The Internet of Things in Health, Social Care, and Wellbeing

   Författare :Andrés Laya; Jan Markendahl; Jesus Alonso-Zarate; Stefan Lundberg; Miquel Oliver Riera; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internet-of-Things; Enabling ICT; Social care; Wellbeing; Business models; Business Ecosystems; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The Internet of Things (IoT) enables opportunities to remotely sense and control objects via communication networks. We study services based on connected devices and the collaboration they generate between the ICT and the Health, Social Care and Wellbeing (HSCWB) industries. LÄS MER

5. 14. Partition Tolerance and Data Consistency in Structured Overlay Networks

   Författare :Shafaat Tallat Mahmood; Seif Haridi; Peter Van Roy; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Structured overlay networks; distributed Hash tables; network partitions and mergers; size estimation; lookup inconsistencies; distributed key-value stores; linearizability; dynamic reconfiguration; replication.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Structured overlay networks form a major class of peer-to-peer systems, which are used to build scalable, fault-tolerant and self-managing distributed applications. This thesis presents algorithms for structured overlay networks, on the routing and data level, in the presence of network and node dynamism. LÄS MER

7. 15. Constraint-Based Register Allocation and Instruction Scheduling

   Författare :Roberto Castañeda Lozano; Christian Schulte; Ingo Sander; Mats Carlsson; Laurent Michel; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; constraint programming; combinatorial optimization; register allocation; instruction scheduling; compiler construction; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Register allocation (mapping variables to processor registers or memory) and instruction scheduling (reordering instructions to improve latency or throughput) are central compiler problems. This dissertation proposes a combinatorial optimization approach to these problems that delivers optimal solutions according to a model, captures trade-offs between conflicting decisions, accommodates processor-specific features, and handles different optimization criteria.
