Information flow analysis of scientific workflows
Recently, scientific workflows have emerged as a platform for automating and accelerating data processing and data sharing in scientific communities. Many scientific workflows have been developed for collaborative research projects that involve a number of geographically distributed organizations. Sharing of data and computation across organizations in different administrative domains is essent...
متن کاملReproducibility Analysis of Scientific Workflows
Scientific workflows are efficient tools for specifying and automating compute and data intensive in-silico experiments. An important challenge related to their usage is their reproducibility. In order to make it reproducible, many factors have to be investigated which can influence and even prevent this process: the missing descriptions and samples; the missing provenance data about the enviro...
متن کاملScientific Workflows
In recent years workflows have emerged as a key technology that enables large-scale computations on distributed resources. Workflows enable scientists to design complex applications that are composed of individual application components or services. Often times these components and services are designed, developed, and tested collaboratively. Because of the size of the data and the complexity o...
متن کاملTowards Information Flow Auditing in Workflows
The paper proposes an approach for compliance audits in workflow environments based on the tracking of information flow. Requirements are formalized as a binary relation on the workflow principals. The workflows’ execution logs are transferred into graph-based representations of the explicit information flows (dataflows) and adherence to compliance requirements is checked while traversing these...
متن کاملViews on Scientific Workflows
Workflows are becoming more and more important in e-Science due to the support they provide to scientists in computer simulations, experiments and calculations. Our experiences with workflows in this field and the literature show that scientific workflows consist of a large number of related information. This information is difficult to deal with in a single perspective and has changing importa...
