Due to the fall in the price of multicore processors, today's non-dedicated clusters tend to include this kind of hardware in their configurations. How general purpose Operating System (OS) schedulers will support requirements like the coexistence of soft-real time, best effort or interactive applications are open questions that need to be addressed carefully. For these reasons, new user interfaces,...
gLite is one of the largest distributed computing infrastructures in operation. It provides access to hundreds of different clusters - all installed and maintained in different ways. This paper analyses the difficulties which users typically experience when moving from their own workstation via clusters or supercomputers to the grid. Based on that analysis, this paper presents tools, which helps to...
Media spaces provide users with flexible support for easy interaction with technology and with each other, both at the same place and over distance. From a technological perspective the development of these environments is often inefficient, since most environments are developed specifically, without any synergies or reuse of previous concepts and implementations. In this paper we present the cooperative...
Facing computing and data intensive problems scientists are forced to use all the available resources to solve their problems. This applies to the usage of different distributed e-Infrastructures based on different concepts and architectures. Providing the end user with easy access to such complex systems is a very challenging task and refers to the issues related to the interoperability and interoperation...
