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 …

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 …
