  1. 6. Efficient Implementation of Concurrent Data Structures on Multi-core and Many-core Architectures

    Författare :Bapi Chatterjee; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronization Primitives; Lock-free Binary search tree; Lock-free; Concurrent Data Structures;

    Sammanfattning : Synchronization of concurrent threads is the central problem in order to design efficient concurrent data-structures. The compute systems widely available in market are increasingly becoming heterogeneous involving multi-core Central Processing Units (CPUs) and many-core Graphics Processing Units (GPUs). LÄS MER

  2. 7. Learning computer systems in a distributed project course The what, why, how and where

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anders Berglund; Uppsala universitet.; Uppsala universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; computer science education; computer science education research; computer networking; computer systems; phenomenography; activity theory; learning; higher education; team collaboration; remote collaboration; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; SOCIAL SCIENCES Social sciences Education Subject didactics; SAMHÄLLSVETENSKAP Socialvetenskap Pedagogik Ämnesdidaktik; Computer Systems; Datorteknik;

    Sammanfattning : Senior university students taking an internationally distributed project course in computer systems find themselves in a complex learning situation. To understand how they experience computer systems and act in their learning situation, the what, the why, the how and the where of their learning have been studied from the students’ perspective.

  3. 8. Set Constraints for Local Search

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Magnus Ågren; Uppsala universitet.; Uppsala universitet.; SICS.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Datavetenskap; Computer Science; Computer science; combinatorial problems; constraint-based local search; constraint-directed search; constraint programming; incremental algorithms; monadic existential second-order logic; neighbourhoods; penalty; set variables; set constraints; variable conflicts;

    Sammanfattning : Combinatorial problems are ubiquitous in our society and solving such problems efficiently is often crucial. One technique for solving combinatorial problems is constraint-based local search. Its compositional nature together with its efficiency on large problem instances have made this technique particularly attractive. LÄS MER

  4. 9. Integrated Register Allocation and Instruction Scheduling with Constraint Programming

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Roberto Castañeda Lozano; Roberto Castaneda Lozano; KTH.; Computer Systems Laboratory.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

    Sammanfattning : This dissertation proposes a combinatorial model, program representations, and constraint solving techniques for integrated register allocation and instruction scheduling in compiler back-ends. In contrast to traditional compilers based on heuristics, the proposed approach generates potentially optimal code by considering all trade-offs between interdependent decisions as a single optimization problem.

    Sammanfattning : A challenge for the clinical management of Parkinson's disease (PD) is the large within- and between-patient variability in symptom profiles as well as the emergence of motor complications which represent a significant source of disability in patients. This thesis deals with the development and evaluation of methods and systems for supporting the management of PD by using repeated measures, consisting of subjective assessments of symptoms and objective assessments of motor function through fine motor tests (spirography and tapping), collected by means of a telemetry touch screen device.
