Odd, I encountered this story at Ars first. There the news was "up to
16 processors" and one day in the future up to 512 processors. This
article and the SGI tech sheet and press release don't seem to mention
any current barrier to 512P.
It's about time someone had some sense. All this time intel is trying
to force a chip to a market (Itanium 2->servers) instead of forcing a
market to move to their chip (workstation users->Itanium 2). Of course
they have been unsuccessful. Itanium 2 is not a server, it's a workstation.
A lot of that (workstation) market relies on high-cost, complex,
independently developed, relatively low-volume software though and the
users can only use what's available. Many of the ISVs got burned with
Risc/6000s, Alphas and even, to a certain extent, Suns over the past
10years; even if the hardware system was essentially free to them, which it
usually wasn't, they are much less likely to take on the risks of
conversion/development and the maintenance burden a 2nd or 3rd time.
I believe that AMD64 really has closed any window of opportunity for
Itanium there. Intel's refusal to acknowledge the existence of Yamhill for
the past 2(?) years... followed by the eventual announcement of EM64T,
seems to indicate, to me anyway, that even they seem to have seen the
light. Any residual reluctance is, of course, understandable but the
"market" is speaking:
http://www.ptc.com/partners/hardware/current/itanium_letter.htm (sorry if
you've already seen that) and putting it quite bluntly too.
Looking at the numbers, for what we paid IBM for monthly Risc/6000
maintenance charges a few years back, we can now get/build a workstation
class PC every 2 months or so. Hardware maintenance cost on a current
workstation would, of course, be much less than back then but I'd think it
would be a brave soul who would pass it up vs. how they would on a PC-based
system. Even without the initial cost, it just doesn't add up for Itanium.
