Developing Scientific Software

Not all scientific computing is high-performance computing—the variety of scientific software is huge. Such software might be complex simulation software developed and running on a high-performance computer, or software developed on a PC for embedding into instruments; for manipulating, analyzing or visualizing data or for orchestrating workflows. This special issue provides some flavor of that variety. It also explores the question of how the development of scientific software can be improved.

Software security varies greatly

Veracode has analyzed more than 9,000 applications over the past 18 months, across 40 different industry sectors. These applications are both internally developed enterprise applications and those purchased by enterprises from software vendors. We measured the security quality of third-party software from large and small software vendors and compared the security quality of soft-ware written different languages for different industry sectors. The paper will show that there are significant differences in the quantity and types of vulnerabilities in software due to differences in where the software was developed, the type of software it is, in what language it was developed, and for what type of business the software was developed for.     

On coping with real-time software dynamic inconsistency by built-in tests

In real-time systems, dynamic inconsistencies of software are hardly detected, diagnosed and handled. A built-in test (BIT) method is developed to cope with software dynamic inconsistency. BIT is defined as a new kind of software testing which is explicitly described in object-oriented source code as member functions. BITs can be activated at any designed moment at run-time to detect, diagnose and handle software dynamic inconsistencies. This paper develops a new approach to cope with software dynamic inconsistencies at run-time by BITs. In this paper, the concept of BITs is introduced. The standard structures which incorporate BITs into conventional object-oriented software are analysed. Reuse methodologies for BITs in OO software are developed at object and system levels. A case study is provided for showing how to create BIT and how to inherit and reuse BITs in OO programming. Methods for incorporating BITs into OO software at object, class and system levels are provided. An approach to dynamic inconsistency control by BITs is developed.

A model for software reuse

Software reusability is widely believed to be a key to help overcome the ongoing software crisis by improving software productivity and quality. New computer technology and the demands of an advancing society require new and more complicated software. It is unrealistic to expect that every software system can be developed solely reusing existing software; however, software reusability has proven to be a way of enhancing software productivity and quality in different organizations. It is also believed that reuse of code segments alone does not significantly reduce software development effort.By creating reuse support information while software is being developed (when the software is best known to software developers), the reuse effort for both software development and maintenance can be potentially reduced.In this paper, five types of RSI are presented: Semantic Web, Horizontal Web, Vertical Web, Syntactic Web, and Alternative Web. We collectively call these five webs a Quintet Web. The Semantic Web enables software developers to locate a software segment. The Horizontal Web provides a means to reuse a block of soflware along with other types of software from other phases of a development process. The inter-phase integration of software can be performed through this Web. The Vertical Web identifies the vertical relationship of a software block to its operational environment. The Syntactic Web locates all statements in which a variable is used. The Alternative Web provides alternative software blocks that perform an identical operation.A prototype of the Quintet Web is presented.
