1. 1. Decentralized Control of Networked Systems : Information Asymmetries and Limitations

   Författare :Farhad Farokhi; Karl Henrik Johansson; Jeff S. Shamma; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked Control Systems; Decentralized Control; Limited Model Information; Transportation Systems; Sensor Scheduling;

   Sammanfattning : Designing local controllers for networked systems is challenging, because in these systems each local controller can often access only part of the overall information on system parameters and sensor measurements. Traditional control design cannot be easily applied due to the unconventional information patterns, communication network imperfections, and design procedure complexities. LÄS MER

3. 2. 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. 3. Software Concerns for Execution on Heterogeneous Platforms

   Författare :Hugo Sica de Andrade; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software Architecture; Heterogeneous Platforms; Software Deployment; Interprocess Communication;

   Sammanfattning : Context: Heterogeneous computing, i.e., computing performed on different types of execution units, such as CPUs, GPUs, FPGAs, has shown to be a feasible path towards higher performance and less energy consumption. Heterogeneous platforms are specialized on specific types of computation, e. LÄS MER

5. 4. Testing of Heterogeneous Systems

   Författare :Nauman Ghazi; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Testing; Heterogeneous systems; Information sources; Test selection;

   Sammanfattning : Context: A system of systems often exhibits heterogeneity, for instance in implementation, hardware, process and verification. We define a heterogeneous system, as a system comprised of multiple systems (system of systems) where at least one subsystem exhibits heterogeneity with respect to the other systems. LÄS MER

7. 5. Hardware/Software Co-Design of Heterogeneous Manycore Architectures

   Författare :Süleyman Savas; Tomas Nordström; Zain Ul-Abdin; Jari Nurmi; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardware software co-design; manycore architectures; heterogeneous manycores; processor design; parallel computing; high performance computing;

   Sammanfattning : In the era of big data, advanced sensing, and artificial intelligence, the required computation power is provided mostly by multicore and manycore architectures. However, the performance demand keeps growing. Thus the computer architectures need to continue evolving and provide higher performance. LÄS MER
