Scaling up workflow-based applications
a r t i c l e i n f o a b s t r a c t Scientific applications, often expressed as workflows are making use of large-scale national cyberinfrastructure to explore the behavior of systems, search for phenomena in large-scale data, and to conduct many other scientific endeavors. As the complexity of the systems being studied grows and as the data set sizes increase, the scale of the computational ...
متن کاملA Bottom-Up Workflow Mining Approach for Workflow Applications Analysis
Engineering workflow applications are becoming more and more complex, involving numerous interacting business objects within considerable processes. Analysing the interaction structure of those complex applications will enable them to be well understood, controlled, and redesigned. Our contribution to workflow mining is a statistical technique to discover workflow patterns from event-based log....
متن کاملApplications of Web-Based Workflow
A web-based workflow system was developed at the Jet Propulsion Laboratory and several pilot applications were developed. We give an overview of the architecture and functionality of the workflow system, describe three pilot workflows that have been or are being deployed, and relate lessons learned.
متن کاملA new 2D block ordering system for wavelet-based multi-resolution up-scaling
A complete and accurate analysis of the complex spatial structure of heterogeneous hydrocarbon reservoirs requires detailed geological models, i.e. fine resolution models. Due to the high computational cost of simulating such models, single resolution up-scaling techniques are commonly used to reduce the volume of the simulated models at the expense of losing the precision. Several multi-scale ...
متن کاملWorkflow-based Services: Infrastructure for Scientific Applications
The way scientists work in traditional sciences has changed drastically in recent years. Computer science is increasingly supporting them in performing and analyzing their experiments. Today, obtaining the raw data from instruments is merely the first step. No longer is the data analyzed on paper or with simple computational tools. Instead, massive amounts of data obtained raw from instruments ...
