Modular application builders (MABs), such as AVS and Iris Explorer[6, 7] are increasingly being used in the visualisation community. Such systems can already place compute intensive modules on supercomputers in order to utilise their power. This paper details two major projects at EPCC which attempted to fully integrate the MAB concept with a distributed memory MIMD (DM-MIMD) environment. The work presented was driven by two goals, efficient use of the resource and ease of use by programmer and end user. We present a model of MABs and describe the major problems faced, giving solutions to them through two case studies. 1 Introduction Many modular application builders (MABs) have been built recently and their popularity is growing. It is often the case that the users of MABs wish to utilise parallel supercomputers within the environment. A few years ago, this was only possible by writing a special module that, typically, used socket connections to talk to a remote supercomputer and ...

The aims of the "Visualization in Parallel" (Vipar) project is to produce a comprehensive environment for the development of parallel visualization modules in systems such as the Application Visualization System (AVS), Iris Explorer, IBM Data Explorer (DX) and Khoros. This paper presents an overview of the project and describes the libraries developed to support the first phase of the work which is a tool to describe parallel visualization modules. This work is funded as part of the EPSRC project (GR/K40390) Portable Software Tools for Parallel Architectures (PSTPA). Keywords: Visualization, AVS, Iris Explorer, IBM Data Explorer, Parallel 1 Introduction This paper first describes the aims of the Visualization in Parallel (Vipar) project and, as background material, an overview of the problems associated with producing parallel visualization systems. Section 2 describes the Vipar system architecture and related components are covered in section 3. The terms and concepts used in the s...

The aims of the "Visualization in Parallel" (Vipar) project is to produce a comprehensive environment for the development of parallel visualization modules in systems such as the Application Visualization System (AVS), Iris Explorer, IBM Data Explorer (DX) and Khoros. This paper presents an overview of the project and will describe the data decomposition tool and libraries developed during the first phase of the work to support the writing of parallel visualization modules.
