OpenMP in the field: Anecdotes from practice

Abstract

The High Performance Computing Support Unit at UNSW has a mission to support and encourage the scaling of computationally intensive applications from existing desktop implementations. OpenMP is a good match for this task. This paper reports on several projects in which OpenMP was used to parallelise an application, sometimes successfully, sometimes not so. The interest in these cases is that they are not the usual run of the mill applications that can be parallelised by simply adding a few OpenMP compiler directives, but required some lateral thinking. © Springer-Verlag Berlin Heidelberg 2003.
