Scientific workflows are used to connect together different data sources, components and processes to support research. These interacting components and processes are usually developed independently and may not be directly compatible, requiring considerable effort to integrate them. The execution-centric and implementation-focused nature of existing workflow management methodologies forces scientists to work at the low level of workflow orchestration and implementation. This makes it difficult and time-consuming to verify the provenance of and reuse existing workflows in a new context.

Omnispective Analysis and Reasoning lifts the process of scientific workflow management to a higher level of abstraction in order to support the effective capture and reuse of concepts and ideas (intellectual effort). The research tackles workflow context, provenance and agility at the concept, model and execution levels of scientific workflow management.

Improved support for these concerns will make it easier to rapidly form and evaluate research hypotheses. This will greatly enhance the scientist’s ability to understand and intervene in a rapidly changing world.

This seminar is part of the CECS Seminar Series.

“A sizable number of computational chemists (physicists, biologists and material scientists alike) use a wide variety of tools to perform computation, visualization and presentation. Many a times these are incompatible with each other, necessitating reliance on, often cumbersome, external tools    to perform appropriate conversions. A few of the computational chemists also use myriad programming environments to develop new computational codes or visualization tools. However, there is no environment that succinctly amalgamates programming environments and various tools available to a computational chemist, which many a times hinders easy integration and rapid application development.

“In this talk, I present MeTA Studio, a programmable cross-platform environment for computational chemists that aims to address this issue.”

This seminar is part of the CECS Seminar Series.

Seminar: Can we Increase Software Development Productivity by an Order of Magnitude

Speaker: Shayne Flint, Senior Lecturer, School of Computer Science (SoCS, ANU)

“Demand for software developers is increasing while the number of software engineering and IT students remains stable or in decline. At the same time, there is an increasing need to quickly build software systems in response to rapid social, economic and environmental change. The CECS Software-Intensive Systems Engineering (SiSE) group is addressing these issues by developing novel technology which aims to increase software development productivity by an order of magnitude.

“To achieve this objective we are exploring the use of Model- Driven Engineering (MDE) and ways to improve its effectiveness. Specifically, we are addressing problems in areas such as requirements and stakeholder management; integrating multiple viewpoints, cross-cutting concerns, modelling languages and paradigms; variations in architecture and implementation; model semantics, translation, synchronisation, evolution and reuse; the presence of uncertainty, imperfection and ambiguity; verification, scalability and visualisation. This is a long list, but our research indicates the possibility that many of these problems may be the result of entrenched assumptions that underpin existing approaches to MDE.”

In this seminar Dr Flint will demonstrate a new approach to MDE which is developed from a very different set of assumptions. The approach is proving effective and addresses or eliminates many of the problems with existing approaches. If commercialised, it could have direct and demonstrable economic impact by increasing ICT industry productivity and our ability to rapidly react to emerging opportunities and threats.

This seminar is part of the CECS Seminar Series.

Shayne Flint is a Senior Lecturer at the School of Computer Science, Australian National University, and is an active member of the department’s Software-Intensive Systems Engineering group. He started his career as a RAAF engineering officer and has worked in industry in various software/systems engineering, consulting, marketing, management and commercialization roles. Dr Flint has broad industry experience and is the originator of Aspect-Oriented Thinking, a systematic approach to developing, managing and integrating the multi-disciplinary knowledge and expertise required to understand and improve complex systems. Nowadays, he is driven by a desire to radically improve the productivity of software development, particularly within multi-disciplinary contexts such as environmental science and engineering.
