User tools and languages for graph-based Grid workflows

One of the main objectives of Grid computing is the abstraction from the hardware infrastructure as well as hiding implementation details of software components from the user. A modern Grid infrastructure should enable the user not only to execute single tasks on specified hardware resources but also to compose and execute complex Grid applications on distributed, heterogeneous and unreliable h...

Parameter Space Exploration Using Scientific Workflows

In recent years there has been interest in performing parameter space exploration across “scientific workflows”, however, many existing workflow tools are not well suited to this. In this paper we augment existing systems with a small set of special “actors” that implement the parameter estimation logic. Specifically, we discuss a set of new Kepler actors that support both complete and partial ...

Ontology-Based Support for Graph Algorithms in Online Exploration Workflows

Application domains often include notions that are inherently based on graph structures. In this paper, we propose a comprehensive generic ontology for graphs. It focuses on those aspects of graphs that are useful for workflows that require exploration of relevant parts of potentially large graphs by online algorithms. The goal of the ontology is to include as much information as possible suppo...

Big Data Exploration Via Automated Orchestration of Analytic Workflows

Large-scale data exploration using Big Data platforms requires the orchestration of complex analytic workflows composed of atomic analytic components for data selection, feature extraction, modeling and scoring. In this paper, we propose an approach that uses a combination of planning and machine learning to automatically determine the most appropriate data-driven workflows to execute in respon...
