Line 1:
The '''Parallel Element Processing Ensemble''' (also known as '''PEPE''') was one of the very early [[parallel computing]] systems. This computer was designed and built in the mid 1970s by [[Burroughs Corporation]] at their Great Valley Labs engineering facility in [[Paoli, Pennsylvania]]. The original goal was to build a computer system that could simultaneously track up to 288 incoming [[ballistic missile]] [[warhead]]s.
The design featured an array of 288 (8 x 36) identical processing elements and associative addressing. Each processing element contained a minimum of control logic, the bulk of the control being concentrated in a common control unit. The control unit decoded and issued instructions to all processing elements simultaneously so that the elements were required to execute exactly the same instruction at exactly the same time. The elements were capable of executing a complete single address instruction repertoire permitting any desired arithmetic or logical operation.
Line 7:
Burroughs delivered PEPE to the Ballistic Missile Defense Advanced Technology Center (part of [[US Army]]'s Strategic Defense Command) in [[Huntsville, Alabama]] in 1976.
