A new generation of operating system was born during the last ten years: a distributed operating system oriented network. Three key-concepts are strongly developed: standardization, distribution and parallelism. One of these systems is chorus TM . This project launched at inria has elaborated an architecture for distributed systems. chorus is now being commercialized by the chorus systems company; it will be ported in the next few years on different machines, starting with the sps 7, pc/at and sun . chorus offers unix TM compatibility, is independent of the hardware architecture and of the network. This paper describes a complete computer architecture fitted to chorus , that is based on Transputers and Clippers. It is a message-based multiprocessor architecture called ‘Heterogeneous Parallel Distributed Machine’ ( hpdm ). The project was developed at utc in the iis department. The major feature of the machine rests on the fact that the operating system is executed by a dedicated processor: the Transputer. Users' tasks are executed on a Clipper. These two processors are called a hpd processor. The hpdm is modular and may be composed of five hdp processors. Transputers are fully connected by their serial links, avoiding bus contentions. Clippers have local shared memory accessible by their private bus or by a global bus. A third bus is used by the dmac supporting i/o operations (disk, ethernet , X25) and accessing the local shared memories and private memories of Clippers. This bus permits i/o operations without decreasing global bus bandwidth. hpdms may be connected together, for example by ethernet or X25 network. |
