The Parallel Utilities Library

The paper describes the Parallel Utilities Library (PUL) which has been in development at Edinburgh Parallel Computing Centre (EPCC) since 1991. The primary aim of this project has been to support the porting of commercial and industrial applications to parallel systems by providing commonly required services within a suite of library modules implemented on top of message-passing. The library includes support for task parallelism, domain decomposition, unstructured mesh applications and parallel scalable I/O and has recently been ported to the emerging Message-Passing Interface (MPI) standard. A large number of industrial application codes have been parallelised by making use of PUL and we report on three such projects that have been carried out with Rolls-Royce, AEA Technology and Shell UK.<
