sure - such suggestions are pretty easy to put together, but they do not answer the question: should it be done, and at what cost? I still think they're really being used as a fig-leaf to cover the erection people get when imagining the "next-a-scale" facility. simulations like this are extremely dubious in that they're fundamentally limited by the quality of raw configuration data. it is emphatically not clear that neuroscience is primarily limited by the scale of machines to run simulations. >> power-efficient systems? if power is an important TCO component, why aren't >> we optimizing for it already (in any sized facility)? > > I definitely do for my private projects, as 0.25 EUR/kWh are > a pretty good argument. even retail, fully-delivered rates here are half that. but out of curiosity, does your comment mean that you, for instance, buy arm clusters, or at least LV versions of x86 chips (and high-core, low-clock models), gold/platinum PSUs, etc? (or just do your compute in a location with cheaper power?) regards, mark hahn. _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
