Abstract:

A data processing array is partitioned by electronic control signals into multiple sub-arrays which are established and operate independently of each other. In the preferred embodiment, an operator's console is provided for manually selecting the data processing nodes that are in each sub-array, and a control module is coupled by control channels between the console and the data processing nodes. These control channels carry the control signals directly to the data processing nodes without utilizing the input/output channels which are intercoupled to form the array. One portion of these control signals prevent each node in a sub-array from sending messages on the input/output channels to any node in another sub-array; and another portion of the control signals select a node in each sub-array as a boot node from which a separate operating system and user programs are loaded without utilizing the input/output channels.
