Distinguished Lecture and Alan Turing Centenary Event
Alan Turing’s Other Universal Machine: The ACE
5pm, Wednesday 5th December 2012
Faraday Lecture Theatre, Faraday Building
Tea and coffee is available before the lecture, which starts at 5.30pm.
The lecture is followed by a reception, and by a Swansea Science Café event:
To Kill A Machine
a performance of a play about Alan Turing, starting at 7.30pm, Café West, Fulton House.
In October 1945, shortly after finishing his code-breaking activity at Bletchley Park, Alan Turing was recruited by the National Physical Laboratory to design an electronic digital computer, the ACE (Automatic Computing Engine). The ACE was a highly innovative design that set it apart from all contemporary computers: the machine traded some complexity of programming for an efficiency gain of a factor of at least five. Several commercial derivatives were produced including the highly successful English Electric DEUCE and the Bendix G-15. This lecture describes the genesis of the ACE from Turing’s On Computable Numbers paper of 1936 and John von Neumann’s EDVAC Report of 1945, and its role in the shaping the early computer industry.
