Factoring out ordered sections to expose thread-level parallelism [PDF]

, 2009
With the rise of multi-core processors, researchers are taking a new look at extending the applicability auto-parallelization techniques. In this paper, we identify a dependence pattern on which autoparallelization currently fails.

Unified Schemes for Directive-Based GPU Offloading

IEEE Access
GPU is the dominant accelerator device due to its high performance and energy efficiency. Directive-based GPU offloading using OpenACC or OpenMP target is a convenient way to port existing codes originally developed for multicore CPUs.

Performance Evaluation of a Hybrid Programming Model for RSDFT on T2K Open Supercomputer

Journal of Algorithms & Computational Technology, 2011
Non-uniform memory access (NUMA) systems, where each processor has its own memory, have been popular platform in high-end computing. While some early studies had reported that a flat-MPI programming model outperformed an OpenMP/MPI hybrid programming ...

Implementing OpenMP 4.0 for the NVIDIA PTX architecture in GCC compiler

Труды Института системного программирования РАН, 2018
The paper describes the approach used in implementing OpenMP offloading to NVIDIA accelerators in GCC. Offloading refers to a new capability in OpenMP 4.0 specification update that allows the programmer to specify regions of code that should be executed ...

Nonlinear Wave Simulation on the Xeon Phi Knights Landing Processor

EPJ Web of Conferences, 2018
We consider an interesting from computational point of view standing wave simulation by solving coupled 2D perturbed Sine-Gordon equations. We make an OpenMP realization which explores both thread and SIMD levels of parallelism.
