1. 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.

2. Performance-driven exploration using Task-based Parallel Programming Frameworks
Sammanfattning : .... LÄS MER
3. Leveraging Intermediate Representations for High-Performance Portable Discrete Fourier Transform Frameworks : with Application to Molecular Dynamics
Sammanfattning : The Discrete Fourier Transform (DFT) and its improved formulations, the Fast Fourier Transforms (FFTs), are vital for scientists and engineers in a range of domains from signal processing to the solution of partial differential equations. A growing trend in Scientific Computing is heterogeneous computing, where accelerators are used instead or together with CPUs. LÄS MER
4. Making Sampled Simulations Faster by Minimizing Warming Time
Sammanfattning : A computer system simulator is a fundamental tool for computer architects to try out brand new ideas or explore the system’s response to different configurations when executing different program codes. However, even simulating the CPU core in detail is time-consuming as the execution rate slows down by several orders of magnitude compared to native execution. LÄS MER
5. Large-scale I/O Models for Traditional and Emerging HPC Workloads on Next-Generation HPC Storage Systems
Sammanfattning : The ability to create value from large-scale data is now an essential part of research and driving technological development everywhere from everyday technology to life-saving medical applications. In almost all scientific fields that require handling large-scale data, such as weather forecast, physics simulation, and computational biology, supercomputers (HPC systems) have emerged as an essential tool for implementing and solving problems.
