The OpenMP Implementation of NAS Parallel Benchmarks and its Performance

by H. Jin, H. Jin, M. Frumkin, M. Frumkin, J. Yan, J. Yan , 1999
"... As the new ccNUMA architecture became popular in recent years, parallel programming with compiler directives on these machines has evolved to accommodate new needs. In this study, we examine the effectiveness of OpenMP directives for parallelizing the NAS Parallel Benchmarks. Implementation details ..."

OpenMP for Networks of SMPs

by Y. Charlie Hu , Honghui Lu , Alan L. Cox , Willy Zwaenepoel
"... In this paper, we present the first system that implements OpenMP on a network of shared-memory multiprocessors. This system enables the programmer to rely on a single, standard, shared-memory API for parallelization within a multiprocessor and between multiprocessors. It is implemented via a transl ..."

OpenMP on Networks of Workstations

by Honghui Lu , Y. Charlie Hu, Willy Zwaenepoel , 1998
"... We describe an implementation of a sizable subset of OpenMP on networks of workstations (NOWs). By extending the availability of OpenMP to NOWs, we overcome one of its primary drawbacks compared to MPI, namely lack of portability to environments other than hardware shared memory machines. In orde ..."

An OpenMP Implementation for Multiprogrammed SMPs

by Vasileios K. Barekas, Panagiotis E. Hadjidoukas, Eleftherios D. Polychronopoulos, Theodore S. Papatheodorou
"... In this paper, we present an OpenMP implementation designed for multiprogrammed environments on Intel-based SMPs. This implementation consists of a runtime system and a resource manager, while we use the NanosCompiler to transform OpenMP applications into code with calls to our runtime system. The r ..."

The Design of OpenMP Tasks

by Eduard Ayguadé, Nawal Copty, Ieee Computer Society, Ro Duran, Jay Hoeflinger, Yuan Lin, Federico Massaioli, Xavier Teruel, Priya Unnikrishnan, Guansong Zhang - IEEE Trans. Parallel Distrib. Syst
"... Abstract—OpenMP has been very successful in exploiting structured parallelism in applications. With increasing application complexity, there is a growing need for addressing irregular parallelism in the presence of complicated control structures. This is evident in various efforts by the industry an ..."

, including a rich set of examples and an in-depth discussion of the rationale behind various design choices. We compare a prototype implementation of the tasking model with existing models, and evaluate it on a wide range of applications. The comparison shows that the OpenMP tasking model provides

Implementation and Evaluation of OpenMP for Hitachi
