Big-Iron to Open Up for AMD
vincecate writes "Traditionally the key chips that have allowed companies to
scale multiprocessors to large numbers have been proprietary.
Some examples are the
Cray SeaStar,
SGI NUMAlink,
HP sx1000,
and the
IBM X3/Hurricane.
This proprietary paradigm is about to change to a more open one.
Two companies have developed key chips for
building large Opteron multiprocessors,
and they will be
commercial off-the-shelf parts.
PathScale has
released
InfiniPath
which can be used with an
Infiniband
switch to make
a high-bandwidth low-latency interconnect for a
supercomputer cluster.
The other company is
Newisys,
which
will soon release
the
Horus chip.
This chip will make it possible to build 32 socket
(64-core) shared memory Opteron systems."
Give it another few months and I'm sure Sun will have some server with an obscene number of opterons in it, if thier current direction is any indication ....

SeaStar and InfiniPath (and don't forget the XD1) are great for building non-cache-coherent clusters, but those are mostly useful for running specially-written scientific applications.
Horus is used for building Opteron ccNUMA machines with one OS instance that can run any Linux or Windows apps. It's a very different solution for a different market.
I think this represents a fundamental shift in what "big iron" of the future will be. Instead of a few ultra-reliable, ultra-expensive processors, we will use masses of somewhat-reliable, cheap processors. The 64-processor clusters are just the beginning. Sony/IBM's Cell is a step in that direction; lots of little processors, rather than one big one. Big Iron is just what you make of it, after all, and ultra-reliability in practice doesn't have to mean an archaic architecture in design.
Proprietary is proprietary. AMD chips are no more "open" than any other vendor's chips.
So where I can buy the AMD server with near full redundancy?
Or the server which can run highly debugged application written in mainframe assembler in 60's or 70's ?
Or atleast AMD computer with SINGLE memoryspace atleast 1TB in size?
And also how many decades of uptime is for the operating system which is used with the new AMD computer?
The horus is more or less getting close to midrange server in number of processor while it won't bring it to the reliability requirements of midrange server, to get that it would have to run its own memory controllers instead of cheap ass opteron controllers which lack for example hotswappable memory.
Sure you get speed, but after taking the speed there is eventually a crash.
The big iron is all about gettin continuing to function no matter what comes.
Only problems outside of box, like earthquake or something similar could bring it down.
Yeah. AMD is doing just fine...
Its eating the cheap ass market, not the big iron.
The price is cheap and its bought where the crash proof means better than windows which is like saying saying its unsinkable since it does better in open seas than normal rowboat used in lakes.
Lets put it this way. x86 is just used in low end boxes and in clusters of lowend boxes. And those things are not for everything. They can do much but not everything. They are cost effective when you compare only the purchase price. But not so cost effective when downtime costs a lot.
There is probably order of magnitude or TWO orders of magnitude of what joe slashdotter thinks big iron and what businesses have in big iron as in price range.
Emacs is good operating system, but it has one flaw: Its text editor could be better.
A 32-way SMP dual-core opteron box is a serious threat to Sun Enterprise boxes with 64 to 128 UltraSparc, even the hardware partitioning doesn't mean as much when you can just use two or more x86-64 boxes at probably less than half the price.
Would you buy that from Mom or Pop?
A Sun Enterprise system is a system that is supported by the vendor for its OS (Solaris) and the hardware as well as other players, as the other systems you mention.
A 32-way SMP dual-core opteron box is just a figment of your imagination without a corresponding operating system to match. (You would have gotten another +1 if you had mentioned Linux).
My point is that there is more to a system than just the hardware. Sure, a 32-way SMP dual-core opteron box might be a great (overpriced and expensive) web server and a nice high end box for number crunching, but most of the larger systems are part of critical systems that cannot fail or garble your data. A 32-way SMP dual-core opteron box sounds great, but offers nothing to those whose reputations and careers depend on the system fulfilling its job.
