Abstract. The UNICORE Grid-technology provides a seamless, secure and intuitive access to distributed Grid resources. In this paper we present the recent evolution from project results to production Grids. At the beginning UNICORE was developed as a prototype software in two projects funded by the German research ministry (BMBF). Over the following years, in various European-funded projects, UNICORE evolved to a full-grown and well-tested Grid middleware system, which today is used in daily production at many supercomputing centers worldwide. Beyond this production usage, the UNICORE technology serves as a solid basis in many European and International research projects, which use existing UNICORE components to implement advanced features, high level services, and support for applications from a growing range of domains. In order to foster these ongoing developments, UNICORE is available as open source under BSD licence at SourceForge, where new releases are published on a regular basis. This paper is a review of the UNICORE achievements so far and gives a glimpse on the UNICORE roadmap.
DEISA is a consortium of leading national supercomputing centers that is building and operating a persistent distributed supercomputing environment with continental scope in Europe. To integrate their resources, the DEISA partners have adopted the most advanced middleware and applications currently available. The consortium decided to embrace UNICORE as a job submission interface for the DEISA grid infrastructure. UNICORE is the foremost European grid technology able to hide the complexity of the underlying resources providing a user-friendly graphical user interface for job submission. This paper presents the deployment solution and strategies implemented by DEISA in order to adapt UNICORE for their infrastructure.
