ORNL Run Frontier at an Exascale with 52 GFlops a watt.

  From The Register article …. Frontier marks the first publicly benchmarked exascale computer by quite a margin. The ORNL system is well ahead of Fugaku’s 442 petaflops of performance, which was a strong enough showing to keep Fugaku in the top spot for two years. Reaching exascale status is one thing, but many expected […]

Fifty years of Cray supercomputers in 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 Cray-1  SN34, peaking ‘under the covers’ of this remarkable machine. The talk also illuminates how these machines evolved and sample some of what was achieved

Supercomputers going cheep ( too cheep ? ) 1997

The end of the ’90s was tough few years for supercomputers. These articles describe the spat that broke out between Cray and NEC a Japanese firms that was accused of selling supercomputers at less than cost price. After the spat was settled Cray entered an agreement to resell NEC supers SX-5 & SX-6 into the

NCAR / UCAR a research site with a long association with Cray supercomputers.

The National Centre for Atmospheric Research NCAR/UCAR in Colorado has a long association with Cray supercomputers. Starting in 1977 with the Cray-1 SN3 the site invested in some the best supercomputers available.  More recently a Cray Petaflop class machines will be used to explore climate research. In 2024 the site has commissioned Derecho a 19

Delayed delivery obsoleted a Cray XMP-EA SN1205 before delivery.

This cautionary tale of how a USD10 million Cray machine was built but never delivered due to regulatory delay. Turns out it was not super-computers but more likely to be a rogue scientist that let the nuke secrets out the flask. From Wikipedia:  “In 2004, the Pakistani metallurgist Abdul Qadeer Khan, a key figure in

Cray Research systems install base in the ’90s

This chart shows the approximate installed base of active Cray Research systems during the 1990s. The  data that shows the XMP (red) being phased out in favour of the YMP (green) and the rise of the smaller J90 and EL systems (orange and yellow) in the later 1990s. The peek system install base in 1996 being
