a Chorus-based operating system to support integrated real-time and UNIX systems for present and future generations of transputer systems

Objectives

The objective of HARMONY is to produce integrated real-time and Unix systems for present and future generations of transputers based on the Chorus modular distributed operating system, and so accelerate the commercial availability of Chorus technology on the transputer processor family. The project intends to harmonise the application programming environment across the widest possible range of transputer-based hardware platforms. The developments proposed represent a complete family of modular Unix-based operating systems for parallel and real-time systems, ranging from a stand-alone distributed nucleus for embedded systems to either a Unix system V (release 4.0) or a parallel UNIX system (release 3.2).

The key goals are to:

The results of the nucleus and scheduler design work will be used to better understand the advanced operating system support requirements for future generations of transputers.

Progress and Results

An implementation of the Chorus real-time microkernel and UNIX server on the T800/i860 based Archipel Volvox machine has been completed. These form part of the Volvix operating system.

Chorus T800 release 0.4 has been integrated in the transputer-based data acquisition system for the Positron Emission Tomography (PET) rotating scanner at the CHU-Geneva by CERN. The data obtained is transferred onto the IPN - Lausanne parallel reconstruction network, consisting of about 40 transputers, which provides a 3D reconstructed scan image.
