Fifty years of Cray supercomputers was celebrated with a virtual tour hosted by TNMOC in UK on 6th April 2022. This virtual talk explored the physical and logical structure of a Cray-1, peaking ‘under the covers’ of these remarkable machines. The talk also illuminates how these machines evolved and samples some of what was achieved using Cray supercomputers in the UK. Recording of talk is here. Print of slides and other updates are posted here.
Upcoming 50th Anniversary celebration events :
Chippewa Falls WI on 25th September 2022
