Abstract
Array processors are made by assembling individual microcomputer elements into an array. Larger arrays are called massively parallel processors. Some can operate in SIMD, while others can operate in MIMD, or SIMD and MIMD in special configurations. In a SIMD array of processors, there is a need to partition the processors into groups related to the type of problem they contain. When the grouping is the result of a computation within the processing element, it is desirable that each processing element be capable of assigning itself to a group, or maybe several groups. This disclosure describes a means of assigning processing elements to groups as an array function conducted in parallel by all active processing elements in the array, and then using grouping to select certain processing elements for a computation that is unique to the group.
