Supporting the Everyday Work of Scientists: Automating Scientific Workflows
This paper describes an action research project that we undertook with National Research Council Canada (NRC) scientists. Based on discussions about their \ud
difficulties in using software to collect data and manage processes, we identified three requirements for increasing research productivity: ease of use for end- \ud
users; managing scientific workflows; and facilitating software interoperability. Based on these requirements, we developed a software framework, Sweet, to \ud
assist in the automation of scientific workflows. \ud
\ud
Throughout the iterative development process, and through a series of structured interviews, we evaluated how the framework was used in practice, and identified \ud
increases in productivity and effectiveness and their causes. While the framework provides resources for writing application wrappers, it was easier to code the applicationsâ functionality directly into the framework using OSS components. Ease of use for the end-user and flexible and fully parameterized workflow representations were key elements of the frameworkâs success. \u
Dagstuhl News January - December 2006
"Dagstuhl News" is a publication edited especially for the members of the Foundation "Informatikzentrum Schloss Dagstuhl" to thank them for their support. The News give a summary of the scientific work being done in Dagstuhl. Each Dagstuhl Seminar is presented by a small abstract describing the contents and scientific highlights of the seminar as well as the perspectives or challenges of the research topic
Approaches to Compute Workflow Complexity
During the last 20 years, complexity has been an interesting topic that has been investigated in many fields of science, such as biology, neurology, software engineering, chemistry, psychology, and economy. A survey of the various approaches to understand complexity has lead sometimes to a measurable quantity with a rigorous but narrow definition and other times as merely an ad hoc label. In this paper we investigate the complexity concept to avoid a vague use of the term `complexity\u27 in workflow designs. We present several complexity metrics that have been used for a number of years in adjacent fields of science and explain how they can be adapted and use to evaluate the complexity of workflows
06302 Abstracts Collection -- Aspects For Legacy Applications
From 26.07.06 to 29.07.06, the Dagstuhl Seminar 06302 ``Aspects For Legacy Applications\u27\u27 was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl.
During the seminar, several participants presented their current
research, and ongoing work and open problems were discussed. Abstracts of
the presentations given during the seminar as well as abstracts of
seminar results and ideas are put together in this paper. The first section
describes the seminar topics and goals in general.
