    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance analysis; cache performance; multicore performance; memory system; memory bandwidth; memory contention; performance prediction; multi-threading; multiprocessing systems; program diagnostics; commodity multicores; multithreaded program resource requirements; performance counters; scalability bottleneck; scalability improvement; Computer Science; Datavetenskap;

    Sammanfattning : Application performance on computer processors depends on a number of complex architectural and microarchitectural design decisions. Consequently, computer architects rely on performance modeling to improve future processors without building prototypes. LÄS MER

  3. 2. Improving Performance and Quality-of-Service through the Task-Parallel Model​ : Optimizations and Future Directions for OpenMP

    Sammanfattning : With the failure of Dennard's scaling, which stated that shrinking transistors will be more power-efficient, computer hardware has today become very divergent. Initially the change only concerned the number of processor on a chip (multicores), but has today further escalated into complex heterogeneous system with non-intuitive properties -- properties that can improve performance and power consumption but also strain the programmer expected to develop on them.

  4. 3. Implementation of complex polarization propagator theory for linear response properties of large molecular systems

    Författare :Manuel Brand; Patrick Norman; Berta Fernández Rodríguez; KTH; []

    Sammanfattning : Since its beginning, the remarkable development from the first commercially available computers toward exascale supercomputers just within the span of a lifetime has been closely intertwined with the perpetual quest for the utilization of the arising computing power for the avail of theoretical chemistry. With the aim of further pushing the limits of computationally accessible molecular system sizes, this thesis includes the presentation of programming efforts, which brought forth two quantum chemical software codes, as well as a range of ab initio studies on carbon-based systems, enabled by the former.
