1. 1. Rethinking Speculative Execution from a Security Perspective

   Författare :Christos Sakalis; Magnus Själander; Alexandra Jimborean; Stefanos Kaxiras; Josep Torrellas; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer architecture; speculative execution; processor; security; out-of-order execution; side-channel; microarchitectural replay; microarchitecture; Delay-on-Miss; Ghosts; Delay-on-Squash; Computer Science; Datavetenskap;

   Sammanfattning : Speculative out-of-order execution is one of the fundamental building blocks of modern, high-performance processors. To maximize the utilization of the system's resources, hardware and software security checks in the speculative domain can be temporarily ignored, without affecting the correctness of the application, as long as no architectural changes are made before transitioning to the non-speculative domain.

3. 2. Coarse detritus in oligotrophic lake littoral zones : utilization by intervertebrates and contribution to carbon flow

   Författare :Irene Bohman; Jan Herrman; Lars Tranvik; Jan Stenson; Mark O. Gessner; Högskolan i Kalmar; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shredders; Biodiversity; Ecosystem; Limnology; Nattsländor; Sjöar; Kol; Biologisk nedbrytning; Freshwater ecology; Limnisk ekologi; Akvatisk ekologi; Aquatic Ecology;

   Sammanfattning : Syftet med denna avhandling är att öka förståelsen av hur grovt organiskt material, sk grovdetritus, tex löv och makrofytrester, bryts ner i sjöars strandzoner. Motivet bakom intresset för detta är att små näringsfattiga sjöar i skogsrika områden ofta är beroende av tillförsel av energi utifrån och att nedbrytningen av grovdetritus är relativt lite undersökt i sjöar.

4. 3. Architectures and Compilation Techniques for a Data-Driven Processor Array

   Författare :Jesper Vasell; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis presents two processor array architectures and a program transformation technique, which are aimed at efficient exploitation of fine-grain parallelism. The class of architectures considered are fine-grain processor arrays with a data-driven execution model. LÄS MER

5. 4. 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

7. 5. Locality-aware Scheduling and Characterization of Task-based Programs

   Författare :Ananya Muddukrishna; Mats Brorsson; Christoph Kessler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Locality-aware; Task scheduling; OpenMP; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Modern computer architectures expose an increasing number of parallel features supported by complex memory access and communication structures. Currently used task scheduling techniques perform poorly since they focus solely on balancing computation load across parallel features and remain oblivious to locality properties of support structures.
