UNICORE and GRIP: experiences of grid middleware development

We describe our experiences with the UNICORE Grid environment. Several lessons of general applicability can be drawn in regard to user uptake and security. The principal lesson is that more effort should be taken to be made to meet the needs of the target user community of the middleware development. Novel workflow strategies, in particular, should not be imposed on an existing community

High-performance computer management based on Java

Coupling of distributed computer resources connected by a high speed network to one virtual computer is the basic idea of a metacomputer. Access to the metacomputer should be provided by an intuitive graphical user interface (GUI), ideally WWW based. This paper presents a metacomputer architecture using a Java based GUI. The concept will be discussed with regard to security, communication, scalability, and the integration into existing frameworks

Building a metacomputer requires a software for interacting with different operating systems and different resource management systems. In addition, a uniformed graphical user interface is needed, supporting a single sign-on environment, to establish a homogeneous view of the metacomputer. The WWW based batch interface to Cray Systems at the Research Centre Julich ([BHB0138]) is a..
