In 2004 we have launched the Business In the Grid (BIG) project to, firstly, make business aware of Grid technology and, secondly, try to explore new business models. Personal interviews and an online survey were done to gain dissemination of Grid computing and collect information about the possibilities and challenges of business in the Grid. In this paper… (More)
In this paper we present the Vienna Parallel Input Output System (ViPIOS), a novel approach to enhance the I/O performance of high performance applications. It is a client-server based tool combining capabilities found in parallel I/O runtime libraries and parallel le systems.
Automatic construction of workflows on the Grid currently is a hot research topic. The problems that have to be solved are manifold: How can existing services be integrated into a workflow, that is able to accomplish a specific task? How can an optimal workflow be constructed in respect to changing resource characteristics during the optimization process?… (More)
Across a wide variety of fields, huge datasets are being collected and accumulated at a dramatical pace. The datasets addressed by individual applications are very often heterogeneous and geographically distributed. An important factor of the strength of a modern enterprise is its capability to effectively store and process information. As a legacy of the… (More)
Composing grid services to workflows, which solve specific problems is not a trivial task. Various parameters like for example timing constraints, desired quality of solution, availability of (computing) resources, error recovery, payment and security issues, to name only a few, have to be considered. The heterogeneity and the highly dynamic nature of the… (More)
