Abstract (en)
[origin: WO9936851A1] A scalable single system image ("S3I") operating system architecture for a multi-processing computer system having separate service (16) and computational (18) processors and wherein a unique distinction exists between the processors but both have shared, common access to all of the computer system memory. The computational processors have no input/output ("I/O") devices mapped directly onto them while the service processors have full I/O capability. A single operating system software image presents a single system application programming interface to application programs across all of the processors and a communication mechanism between the computational and service processors allows multiple requests to the service processors and fast, asynchronous interrupt responses to each request. A computational scheduler executes on each computational processor and provides the interface to the service processors where the operating system software executes.
