Unified Schemes for Directive-Based GPU Offloading
IEEE AccessGPU 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.

, 2008 The memory model of OpenMP has been widely misunderstood since the first OpenMP specification was published in 1997 (Fortran 1.0). The proposed OpenMP specification (version 2.5) includes a memory model section to address this issue. This section unifies and clarifies the text about the use of memory in all previous specifications, and relates the ...

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 ...

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.

Automatic relative debugging of OpenMP programs [PDF]
In this work we show how automatic relative debugging can be used to find differences in computation between a correct serial program and an OpenMP parallel version of that program that does not yield correct results.
