Towards Transactional Memory for OpenMP [PDF]

, 2014
The OpenMP specification lacks a composable shared memory concurrency mechanism: the current OpenMP concurrency mechanisms, such as OMP critical, locks, or atomics, do not support composition. In this paper, we motivate the need for transactional memory (TM) in OpenMP.

The HPCG benchmark: analysis, shared memory preliminary improvements and evaluation on an Arm-based platform [PDF]

, 2018
The High-Performance Conjugate Gradient (HPCG) benchmark complements the LINPACK benchmark in the performance evaluation coverage of large High-Performance Computing (HPC) systems. Due to its lower arithmetic intensity and higher memory pressure, HPCG is

Analysis of Parallel Algorithms on SMP Node and Cluster of Workstations Using Parallel Programming Models with New Tile-based Method for Large Biological Datasets

Bioinformatics and Biology Insights, 2016
Sequence alignment is an important tool for describing the relationships between DNA sequences. Many sequence alignment algorithms exist, differing in efficiency, in their models of the sequences, and in the relationship between sequences.

OpenMP for Accelerators

, 2011
OpenMP [14] is the dominant programming model for shared-memory parallelism in C, C++ and Fortran due to its easy-touse directive-based style, portability and broad support by compiler vendors. Compute-intensive application regions are increasingly being accelerated using devices such as GPUs and DSPs, and a programming model with similar ...

OpenMP tasking analysis for programmers

Proceedings of the 2009 Conference of the Center for Advanced Studies on Collaborative Research - CASCON '09, 2009
As of 2008, the OpenMP 3.0 standard includes task support allowing programmers to exploit irregular parallelism. Although several compilers are providing support for this new feature there has not been extensive investigation into the real possibilities of this extension.

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.

Analysis of OpenMP 4.5 Offloading in Implementations: Correctness and Overhead

Parallel Computing, 2019
The OpenMP language features have been evolving to meet the rapid development in hardware platforms. This journal focuses on evaluating implementations of OpenMP 4.5 target offload features in compilers such as Clang, XL and GCC that are an integral part
