Scientific workflow management and the Kepler system
Many scientific disciplines are now data and information driven, and new scientific knowledge is often gained by scientists putting together data analysis and knowledge discovery “pipelines”. A related trend is that more and more scientific communities realize the benefits of sharing their data and computational services, and are thus contributing to a distributed data and computational communi...
متن کاملProvenance Collection Support in the Kepler Scientific Workflow System
In many data-driven applications, analysis needs to be performed on scientific information obtained from several sources and generated by computations on distributed resources. Systematic analysis of this scientific information unleashes a growing need for automated data-driven applications that also can keep track of the provenance of the data and processes with little user interaction and ove...
متن کاملEarly Cloud Experiences with the Kepler Scientific Workflow System
With the increasing popularity of the Cloud computing, there are more and more requirements for scientific workflows to utilize Cloud resources. In this paper, we present our preliminary work and experiences on enabling the interaction between the Kepler scientific workflow system and the Amazon Elastic Compute Cloud (EC2). A set of EC2 actors and Kepler Amazon Machine Images are introduced wit...
متن کاملContext-aware scientific workflow systems using KEPLER
Data intensive scientific workflows are often modelled using a dataflow-oriented model. The simplicity of a dataflow model facilitates intuitive workflow design, analysis and optimisation. However, some amount of control flow modelling is often necessary for engineering fault tolerant, robust and adaptive workflows. In scientific domain, myriads of environment information are needed for control...
متن کاملScientific Workflow Management System for Clouds
Infrastructure-as-a-Service clouds offer access to a scalable virtualised infrastructure on a pay-per-use-basis. This is greatly beneficial for the deployment of scientific workflows and as a result considerable effort is being made to develop and update existing workflow management systems to support the cloud resource model. The majority of existing systems are designed to work with tradition...
