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 …

EL and C90 Poster Centerfolds

These two posters appeared side by side in Cray Channels V13_N4 as centre folds. Also distributed as wall posters. These two machines, at the opposite ends of the Cray performance spectrum, nevertheless less ran the same UNICOS operating systems and compiler environments. The EL often appeared at larger Cray sites acting as a software development …
