ABSTRACT:
In a loosely coupled multiprocessor environment wherein a plurality of processors (2) are attached to a shared intelligent memory (1), a distributed scheduling mechanism for scheduling of source processors (4) with respective server processes (5) to be executed by the processors (2) upon their attachment to a data message queue (3) contained in the shared intelligent memory (1), the processes (4, 5) using data messages enqueued into, respectively dequeued from said memory (1). According to this scheduling mechanism, an independent scheduler (6) is dedicated to each of the processes of a process group, and all the schedulers monitor the status of the data message queue, and upon receipt of an empty-to-non-empty E-NE signal, the least busy scheduler dequeues shared data from the queue, so that it can be processed by its associated process, without however, loosing fault-tolerance in case of a particular processor failing.
