Confucius: A Tool Supporting Collaborative Scientific Workflow Composition, Jia Zhang, Daniel Kuc, Shiyong Lu Dec 2013

Confucius: A Tool Supporting Collaborative Scientific Workflow Composition, Jia Zhang, Daniel Kuc, Shiyong Lu

Jia Zhang

Modern scientific data management and analysis usually rely on multiple scientists with diverse expertise. In recent years, such a collaborative effort is often structured and automated by a data flow-oriented process called scientific workflow. However, such workflows may have to be designed and revised among multiple scientists over a long time period. Existing workbenches are single user-oriented and do not support scientific workflow application development in a “collaborative fashion.” In this paper, we report our research on the enabling techniques in the aspects of collaboration provenance management and reproduciability. Based on a scientific collaboration ontology, we propose a service-oriented collaboration …

Architecture-Driven Variation Analysis For Designing Cloud Applications, Liang-Jie Zhang, Jia Zhang Aug 2009

Architecture-Driven Variation Analysis For Designing Cloud Applications, Liang-Jie Zhang, Jia Zhang

Jia Zhang

Service Oriented Architecture (SOA) is one central technical foundation supporting the rapidly emerging Cloud Computing paradigm. To date, however, its application practice is not always successful. One major reason is the lack of a systematic engineering process and tool supported by reusable architectural artifacts. Toward this ultimate goal, this paper proposes a variationoriented analysis method of performing architectural building blocks (ABB)-based SOA solution design for enabling cloud application design. We present the modeling of solution-level architectural artifacts and their relationships, whose formalization enables eventbased variation notification and propagation analysis. We report a prototype tool and describe how we extend the …

Collaborative Scientific Workflows, Shiyong Lu, Jia Zhang Jun 2009

Collaborative Scientific Workflows, Shiyong Lu, Jia Zhang

Jia Zhang

In recent years, a number of scientific workflow management systems (SWFMSs) have been developed to help domain scientists synergistically integrate distributed computations, datasets, and analysis tools to enable and accelerate scientific discoveries. As more scientific research projects become collaborative in nature, there is a compelling need of dedicated services to support collaborative scientific workflows on the Internet. This paper reviews the state of the art of the field of scientific workflows towards the support of collaborative scientific workflows, identifies critical research challenges, and presents our ongoing research work aiming to study how to create services supporting collaborative scientific workflows.
