[citation][nom]mapesdhs[/nom]Zak,Writing, "petaflops per second", is redundant. 'petaflops' already includes 'per second', hencethe 'ps' at the end, or deso Titan exhibit the world's first excelarative performance? Other than that, thanks for the update! Surprised it was only 17.59 though, I was expectingit to be higher.Ian.[/citation]
I'm pretty sure that "excelerative" isn't a word and even if it was, it'd probably be spelled more like accelarative.
[citation][nom]ohim[/nom]why do i get negatives for asking the AMD CPU question ? i wasn`t making any fun about it ... just being used to see Intel in there not AMD ...[/citation]
They went with AMD because at the time when "Jaguar" was in development, back in the good old K8 days, AMD had the superior architecture. So as the system evolves the choice to go with Opteron's simply stems from that time.
"If you're curious about why Titan uses Opterons, the explanation is actually pretty simple. Titan is a large installation of Cray XK7 cabinets, so CPU support is actually defined by Cray. Back in 2005 when Jaguar made its debut, AMD's Opterons were superior to the Intel Xeon alternative. The evolution of Cray's XT/XK lines simply stemmed from that point, with Opteron being the supported CPU of choice."
