Massively parallel processors introduces new demands on software systems with respect to performance, scalability, robustness and portability. The increased complexity of the memory systems and the increased range of problem sizes for which a given piece of software is used poses serious challenges for software developers. The Connection Machine Scienti c Software Library, CMSSL, uses several n...

A technique for analyzing multiple-time, single-point datasets is presented, which yields information about the (spectral) variation of MHD elds in directions perpendicular to the mean ow. The analysis can be performed for any homogeneous solenoidal elds, including magnetic and incompressible velocity uctuations. A summary of the associated theory is given, along with initial results obtained u...

This paper briefly describes both organizational and technical issues and approaches involved in creating an operational digital library at the University of Crete, found at http://dlib.libh.uoc.gr. We investigate and describe our approaches and experiences, the last few years, on setting in operation a Digital Library with many collections. We had to analyze the library goals and user needs, t...

The National Software Reference Library (NSRL) is an essential data source for forensic investigators, providing in its Reference Data Set (RDS) a set of hash values of known software. However, the NSRL RDS has not previously been tested against a broad spectrum of real-world data. The current work did this using a corpus of 36 million files on 2337 drives from 21 countries. These experiments a...

reuse research, process, methods, technology, organization, flexible software factory, domainspecific reuse kits Systematic software reuse is a key business strategy that software managers can employ to dramatically improve their software development processes, to decrease time-to-market and costs, and to improve product quality. Effective reuse requires much more than just code and library tec...

If the role of software libraries is to communicate information about software artefacts between software engineers, it is vital that the information be stored in such a manner as to be readily understandable. The designs of existing software libraries present several cognitive impediments to a software engineer, hindering the understanding of library organisation and content. In this paper, a ...

The problem of partitioning a graph into a number of pieces is one of the fundamental tasks in computer science and has a number of applications e.g. in computational mechanics or VLSI design. Finding optimal partitions according to diierent measures is in most cases NP-complete. Nevertheless, a large number of eecient partitioning heuristics have been developed during recent years. The perform...

It is generally acknowledged in visualization research that it is necessary to evaluate visualization artifacts in order to provide empirical evidence on their effectiveness and efficiency as well as their usability and utility. However, the difficulties of conducting such evaluations still remain an issue. Apart from the required know-how to appropriately design and conduct user studies, the n...

The last years a great number of digital library and digital repository systems have been developed by individual organizations -mostly Universitiesand given to the public as open-source software. The advantage of having many choices becomes a great headache when selecting a Digital Library (DL) system for a specific organization. To make the decision easier, we compared five such systems that ...
