As very large digital library collections become more commonplace, software tools must adapt appropriately. This paper reports on an evolution of the Greenstone Digital Library software to support parallel processing during the collection building phase. A series of experiments were conducted to first establish a basic speed-up factor, and then deconstruct the parallelisation process to underst...

We give a survey of the current status of geometric algorithm visualization and ooer some suggestions regarding geometric software library and future directions for visualization software.

High levels of reuse depend on a source of software to reuse. To meet this need many organizations have based their reuse programs on a centrally managed reusable software library (RSL). However, although the library metaphor has guided early work in classification, retrieval, and other areas of reuse technology, experiences vary on whether a centrally-managed RSL or domain-specific RSL provide...

Multicore processors promise dramatic improvements in performance, but their diverse and often unique architectures are a major inhibitor to software adoption. Algorithm libraries that operate at the chip level and are optimized across multiple cores provide the quickest route by which programmers can port or develop highperformance software for multicores. This paper reports on a flexible matr...

Thread-parallelisation and single-instruction multiple data (SIMD) ”vectorisation” of software components in HEP computing has become a necessity to fully benefit from current and future computing hardware. In this context, the Geant-Vector/GPU simulation project aims to re-engineer current software for the simulation of the passage of particles through detectors in order to increase the overal...

BACKGROUND The Smith-Waterman algorithm, which produces the optimal pairwise alignment between two sequences, is frequently used as a key component of fast heuristic read mapping and variation detection tools for next-generation sequencing data. Though various fast Smith-Waterman implementations are developed, they are either designed as monolithic protein database searching tools, which do not...

Greenstone and DSpace are widely used software systems for digital libraries, and prospective users sometimes wonder which one to adopt. In fact, the aims of the two are very different, although their domains of application do overlap. This article describes the two systems and identifies their similarities and differences. We also present StoneD [note 1] a bridge between the production version...

The history of computing can be seen in terms of cultural change engendered by philosophical opposition. In education some key philosophical dichotomies are those of commercial-copyright versus free open source software, and office-centric pedagogies versus rich software libraries to support the whole school curriculum. The ‘Blue File’ software library was generated by four centres supporting s...
