    Please go back and check on how HFH's homes have done in these kinds of situations before you give them a black eye for construction methods. When you look at the pictures from the lower 9th Ward where the levee broke twice, you'll see some big white painted houses. The've been flooded twice now by water pouring through the breaches, but they're still standing. Those are the HFH homes. The ones that didn't suffer anything but water damage and will probably be completely repairable. In previous hurricanes, whole neighboorhoods have been reduced to rubble except for the homes built by HFH. Why? Because the people care about what they're doing and put them together right. They use enough nails on the hurricane straps, and enough everywhere else so that the whole house doesn't fall down from a little gust of wind. 2x4 wood is fine. As long as you connect it right.

    Read my comment again. Most computers over 8 are not smp. It's too much of a headache to handle. I'm pretty sure Sun E10K's are NUMA. In fact, if I remember right, Sun bought the design for them from Cray since SGI didn't want to have a division selling sparc based boxes. I also remember seeing some SGI promotional material about the interconnects on the e10k beinf far slower than the SGI links. So yes, it's possible to build a very large SMP machine. But nobody really does it anymore. Even Opterons are using NUMA because it scales better and is much easier to build logic around.

    Umm, not true. Sun, can hold up to 106 processers in its Sunfire 15K product, or 72 dual-core processors in the E25K.

    SGI's Origin systems are equally large I believe. And manufacturers like IBM also have large SMP machines.


    There's a difference between SMP and NUMA used in the big iron. SMP is normally a shared bus or switch topology with the processors connected to each other with little or no arbitration logic. So if you get above 4 you normally max out the busses as the CPUs try to figure out who's doing what and what instruction comes next. NUMA architecture is somewhere between SMP and clustering. The SGI boxes use c-bricks of 4 CPU's and I think 8GB of RAM. Each c-brick is connected to one or more routers via craylink cables. Get enough of these together and you've got your 512 CPU monster. Sun uses the same idea, but is unfortunatly a LOT slower with their interconnect technology. I've seen 16x SMP boxes before, but they really didn't scale at all. Anything over the standard 4-8 SMP is a waste of CPU's and money.

But even those go out to MIPS licensees to build off of. Crack open a Cisco router. There's a good chance you'll find an R5000 of some sort in there.

    thought that SGI sold a lot of their graphics IP (including many of their top graphics engineers) to NVIDIA a while back, and still have agreements with them. Their IRIX systems sell with VPRO graphics cards, which I believe are repackaged NVIDIA chips with a few extras..

    Or did I miss something?


    Yes, The Vpro series only resembles Nvidia chipes because after it was completed, most of the team went to work for Nvidia and created the geforce with lots of the same ideas behind it. So the original GeForce chips were more like cut down Vpro's than the VPro's were soupped up GeForces if that makes any sense.

    Not intending to start a Holy War, I realize the 64 CPU monsters have their place but their workstations are just ignorant (this is coming from a previous SGI only owner)...
    "These systems were around $40,000 when first released. Each R12000 400MHz has a SpecFP2000 of around 350-360 and so it's approximately equal to an Athlon 1.2GHz. The caveat is that the SpecFP2000 benchmark is actually made up of a bunch of other, smaller, tests. For computational fluid dynamics or neural network image recognition, the 400MHz SGI CPU is 2.5 to 5 times faster than the Athlon!"

    WOW! 2.5 times faster than a 1.2Ghz Athlon!? Man, you'd almost need a $168 2.4 Ghz Athlon [pricewatch.com] to keep up! I wish they made them!

    P.S. The 3.06 Ghz P4 is just under 1000 on the SpecFP benchmark [specbench.org].


    Lets see, the last generation that we have SPEC numbers on for SGI is the 600Mhz R14K. It clocks in at 529 PeakFP compared to 656 Peak FP for the 2.4 GHz MP that was used in the benchmark. That's about a 20% difference in Speed. The original CPU's that he was dealing with, the R12K 400 and the 1.2 K7 are 407 and 352 respectively. That actually gives the SGI a lead by about 15%. Now if the 2.5x increase in an application holds true, I'd say the SGI is still a good deal if you can afford it. Now granted I don't have $40,000 to spend on a workstation, but there are plenty of companies who are willing to spend the extra $30,000 once to get double the performance out of their $60,000 a year engineers for the next two or three years. Also, as is pointed out in the article, the P4 is insanely optimized for SPEC. It's numbers have no real meaning to most realworld applications. If you want to get right down to it, SGI can give you 512 CPU's run through a single Infinite Reality module. No one would actually do this, but it's nice to dream about it once in a while :)

    I can't find the link anymore, but last night I saw an article by Frank Soltis, the cheif scientist over the AS/400 unit. He basically laid out the evolution of the POWER achitecture (not the PowerPC) architecture and how it relates to the new 970 CPU. The first POWER cpu used by IBM was derived from their work with Moto and Apple, but it couldn't be used in the AS/400 line becuase of limitations in the chip. So IBM came up with Power2 (PowerPC AS). This exteneded the functionality of the chip to where it could be used in an AS/400 environment, but was no longer compatible with the PowerPC that Apple and Moto were selling. Then they added the POWER64 instruction set which made the chip faster for business and HPC applications, but drove it further away from the PowerPC platform. The POWER4 chip actuall includes 4 seperate instruction setts. POWER64, POWER32, PowerPC64 and PowerPC32. Adding Altivec and cutting out the second CPU core is what the 970 is. He didn't mention that there was really any overlap between it and the PS3 chip. POWER4 design was started in 96 so there may be some shared philosophy, but probably no real instruction matching between the two. He aslo said that the POWER5 (late next year) and POWER6 architectures would have some OS dependent accelerations put in them. He specifically mentioned that the chip would have an instruction for handling TCP streams instead of having to send several instructions to the CPU at once. And that these will be fully documented so that Linux/OSS can use them. POWER6 will extend that to specific DB2 and Domino calls to accelerate those apps.

I'm sure it's out there, and that if I ever get the right upstream ultrapeer, I can find it. But I haven't yet so the P2P bit is worthless to me.

I've run into this at work, even though we do have a select agreement, we cannot take the image that comes on a Dell PC, add our software to it and ghost it back down to multiple PC's with the same hardware. Violates the terms of the EULA.
