Early Experiences with the OpenMP Accelerator Model other compiler translation details. Further we provide initial runtime support. For our evaluation, we have adapted a few existing OpenMP codes to use the accelerator model directives and present preliminary performance results. Finally, we critique the accelerator model in terms of its impact on d

A Prototype Implementation of OpenMP Task Dependency Support and Smith-Waterman algorithms. By applying the extensions to the two algorithms, we demonstrate significant performance improvement over the standard tasking versions. When comparing our results with those obtained using related dataflow models - OmpSs and QUARK, we observed that the versions using

Locality-Aware Task Scheduling and Data Distribution on NUMA SystemsD Opteron machine with eight NUMA nodes. We identify that both data distribution and locality-aware task scheduling improves performance compared to default policies while still providing an architecture-oblivious approach for the programmer.

BROTH

Open Source Task Profiling by Extending the OpenMP Runtime APIts help in identifying overheads associated with the OpenMP tasking model, e.g., task waiting until a task starts execution or task cleanup etc. These events also help in constructing important parent-child relationships that define tasks’ call paths. The proposed extensions are in line with the new

Dirk Schmidl,Dieter an Mey,Matthias S. Müllere kann es in diesen Fällen unter Effizienzgesichtspunkten ratsam sein, das Monopol zu erhalten. Dies bedeutet jedoch nicht, dass keinerlei kollektiver Handlungsbedarf besteht. Erhaltenswert sind nur Monopole, die “gezähmt” sind, die durch staatliche Regulierung gezwungen werden sich möglichst effizi
