I think (WAG here) that Clearspeed wants people to design a socket
onto motherboards for them. Lowers the costs all around.
But that greatly increases the cost of the motherboards, and mobo
manufacturing is a very price sensitive business. every square cm of
board costs a bunch, all the way through the whole supply chain (mfr,
storage, shipping, etc.)
Yes it does. You would not expect this in the high volume MB business
which is extremely price sensitive. You might expect this on some of
the "specialty" server boards. Not unlike the HTX connector. BTW: any
other HTX cards out there apart from Infinipath? I had heard about one
or two others (RAID/10GBe) but haven't seen too many.
Interesting that there was HUGE economic pressure to integrate the FPU
onto the chip after the 386/387 era. And the whole reason the x87 wasn't
integrated wasn't because of marketing, but because of die size
limitations.
Yup. Remember that. I remember sticking the x87 in the socket and
adjusting toggle switches. Then coding to it in assembler, and setting
up a TSR to hook int 21.
With the 486, the dies got big enough to integrate, and
they've never looked back. I haven't even seen any mass-market
coprocessors of that type (i.e. closely coupled to the CPU) since then.
The coprocessors have tended towards performing some specific function
(e.g. graphics, or PCI bridge with integrated peripherals) and have been
fairly loosely coupled.
This is the coprocessor model that generally works. Server systems have
a minimalistic video chip on the MBs typically. The cost is very low to
do this. An PCIe accelerator board, be it a graphics, IO raid,
networking, or computational accelerator is a reasonable way to add the
offload processing functionality in if you need it.
I would say that there is more potential for a clever soul to
reprogram the guts of Matlab, etc., to transparently share the work
across multiple machines. I think that's in the back of the mind of
MS, as they move toward a services environment and .NET
Lots of people have thought about that for a long time, including
Cleve Moeller. The potential clever soul should be well above
average, and considering MS products, well above MS average programmer.
At least there's lots of MS programmers to draw from, so on a
statistical basis, you'd expect one to pop up.
