Abstract

A system including a plurality of processing units for executing tasks in parallel and a communication network. The processing units are organized into clusters of units, each cluster comprising a local memory. The system includes means for statically allocating tasks to each cluster of units, so that a task of an application is processed by the same cluster of units from one execution to another. Each cluster includes cluster management means for allocating tasks to each of its processing units and space in the local memory for executing them, so that a given task of an application may not be processed by the same processing unit from one execution to another. The cluster management means includes means for managing the tasks, means for managing the processing units, means for managing the local memory and means for managing the communications involving its processing units. The management means operate simultaneously and cooperatively.
