Fifty years of Cray supercomputers April 2022 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 sample 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.
What was it like servicing and repairing complex Cray systems ?
