Paper Abstract

The MEGA Node is a loosely coupled, highly parallel computer, based on transputers. One of its main characteristics is its ability to change the topology of the network, using an electronic switch. It covers a range from 128 to 1024 "worker processors", delivering from 550 to 4400 Mflops peak performance. To achieve these performances, a hierarchical structure has been adopted. This highly parallel machine is issued from the Esprit I P1085 "Supernode" project. The software has to support a wide spectrum of users going from those who wish to obtain maximum performance from the machine to those who wish to use it as a general purpose multi-user parallel machine. This paper describes the different ways to use the MEGA Node and the software environments provided to satisfy all kind of users. The Helios environment is a good example to explain how an operating system can control this machine, particularly the networking management and the fundamental problem of mapping. The MEGA Node has already been used for a wide range of applications like signal/image processing (high and low level), image synthesis, scientific and engineering number-crunching, neural network simulation and logic simulation. Only a few of them are discussed in this paper: medical image analysis and vision and ray tracing.
