ABSTRACT:
In the environment of a plurality of processors interconnected by a shared intelligent memory, a mechanism for the secure passing of messages between tasks operated on said processors is provided. Inter-task message passing is provided by shared intelligent memory for storing the messages transmitted by sending tasks. Further, each processor includes serving means for getting the messages to be sent to the task operated by said each processor. The passing of messages from a processor to the shared intelligent memory and from the latter to another processor is made, using a set of high-level microcoded commands. A process is provided using the message passing mechanism together with redundancies built into the shared memory, to ensure fault-tolerant message passing in which the tasks operated primarily on a processor are automatically replaced by back-up tasks executed on another processor if the first processor fails.
