BlueGene/L Puts the Hammer Down 152

OnePragmatist writes "Cyberinfrastructure Technology Watch is reporting that BlueGene/L has nearly doubled its performance to 135.3 Teraflops by doubling its processors. That seems likely to keep it at no. 1 on the Top500 when the next round comes out in June. But it will be interesting to see how it does when they finally get around to testing it against the HPC Challenge benchmark, which has gained adherents as being more indicative of how a HPC system will peform with various different types of applicatoins."

BlueGene/L now has half of its planned processors and is more than half way to achieving its design goal of 360 teraflops.

      Lets see if I can get this right. I'm going to talk a little bit out of my ass now, but here goes:

      Every 512 node backplane has a peak of 1.4tflop/s according to their design doc.

      The 32k system benched in at 70. The theoretical peak was 91, so the actual performance is about 77 percent of the peak, which is pretty normal.

      The 64k system benched in at 135. The peak should be around 182, so that is 74 percent of the peak.

      The design goal is for 360 at 64k. I'm guessing that 360 is the peak, because my rough estimate calculations put the of 64k nodes at about 364. Lets be nice and assume 70% of peak in the actual machine. That would indicate around 255tflop/s at 64k nodes of actual performance, assuming the thing scales at about the same rate.

      So, they got their math right as long as they are claiming a peak of 360. That's a theoretical max, and so never actually reached. The actual is notably less. My numbers are estimates, and so 364 not equalling 360 doesn't bother me much in the end.

      Anyone care to correct anything?

      Also, can someone explain to me why Cray's Redstorm won't kick this things ass performance wise. Redstorm should have 10k processors, but they are 64bit Opteron 2.4ghz processors with 4x the ram per node. These, I believe, are 700mhz processors.

      I'm confused because Redstorm only has a theoretical peak of about 40tflops off the 10k nodes. IBM's system at 10k should have a peak at around 30tflops. I'm wondering how 64bit opterons at more than 3x the speed could only be 10flops faster at 10k nodes than 700mhz 32bit PPCs with 1/4 the ram. Can someone please explain?

      Also, anyone know why IBM isn't using HPCC. Cray has been using it for the XD1s. I'm guessing the reason IBM hasn't posted results is because they can't even come close in sustained memory bandwidth, mpi latency, and other tests. That's just a guess though. I'd love to hear from someone that actually knows about this stuff.

        Well, it comes down to a few different things.

        First off, Opterons are pretty mediocre at double precision floating point benchmarks, it just isn't what they were designed for. Opterons effectively have only a single FPU (technically they have two, but one only does addition, while the other handles all multiplies), while most competing chips in the HPC arena have two full FPUs. They tend to get spanked by PPCs and Itanium2s, and even Xenons can do better.

        Also, you should note that the modified PPC440s in BlueGene have a disproportionate amount of floating point resources. Making them about equivalent to the 970 in that area mhz for mhz, despite being massively outclassed in integer and vector ops. And the floating point units on those 440s are full 64-bit units (as fpus are on many other ostensibly 32 bit chips, as the bit width of a fpu has nothing to do with the integer units and mmus being 32-bit). Plus the PPC has a fused multiply-add instruction, allowing it to theoretically finish 2 FLOPS/unit/cycle, instead of just one.

        And finally, you should know that individual nodes' ram sizes matter very little for Linpack.

        When you take all that together, it's not too surprising that 700Mhz PPC440s with 2 64-bit FPUs each finishing up to 2 FLOPs/cycle (at least 2 of which must be adds) would perform on par with 2.xGhz Opterons finishing a total of 2FLOPs/cycle (at least one of which has to be an add).

      Well yeah, it's a lot of processors.

      Given the size and complexity of the Cell, 527 of them might present some cooling problems. (Or cogeneration opportunities, if you hook a good liquid cooling system to a steam turbine..

    The HPC Challenge benchmark is especially interesting and I think sheds some light on the design goals IBM had in coming up with the Cell.

    1) Solving linear equations. SIMD Matrix math, check.
    2) DP Matrix-Matrix multiplies. IBM added DP support to their VMX set for Cell (though at 10% the execution rate), check.
    3) Processor/Memory bandwidth. XDR interface at 25.6 GB/s, check.
    4) Processor/Processor bandwidth. FlexIO interface at 76.8 GB/s, check.
    5) "measures rate of integer random updates of memory", hmmmm... not sure.
    6) Complex, DP FFT. Again, DP support at a price. check.
    7) Communication latency & bandwidth. 100 GB/s total memory bandwidth, check (though this could be heavily influenced on how IBM handles its SPE threading interface)

    Obviously, I'm not saying they used the HPC Challenge as a design document, but clearly Cell is meant as a supercomputer first and a PS3 second.

      I think your comparison here is quite unfair to the technological accomplishments of BlueGene/L. This is not simply a case of IBM "throwing more processors" at the problem, but BlueGene is a technological leap over other supercomputers. Not only is BlueGene faster, than for instance the Earth Simulator, but it also consumes FAR LESS power (which in turn minimizes the energy wasted cooling the thing) and takes up much less space. From an article published when BlueGene first overcame the Earth Simulator: "Blue Gene/L's footprint is one per cent that of the Earth Simulator, and its power demands are just 3.6 per cent of the NEC supercomputer." http://www.theregister.co.uk/2004/09/29/supercompu ter_ibm/ So, I say to you, NO! The top 500 race is not simply big companies throwing money at a problem (well, it sort of is), but there is quite a lot of technical accomplishment going on here. You could argue that the people involved may not have the brilliance of Seymore, but they sure do have real talent.

      Yes, but compiling the OpenOffice.org suite is the real time-trial challenge... ;)

      With BlueGene/L, I would hope that the compilation time would be measured in seconds, not hours like with my poor little (by comparison) Athlon.

    What's the scalar performance of one of these beasties?

    Can an Athlon 64 / P4 beat it on scalar code? The whole HPC world has gotten boring since Cray died. Here's why I say that:

    The Cray 1 had the best SCALAR and VECTOR performance in the world.

    The Cray 2 was an ass kicker, the Cray 3 was a real ass kicker (if only they could build them reliably).

    Cray pushed the boundaries, he pushed them too far at some points -- designing and trying to build machines that they couldn't make reliable.

    So it'll be a cold day in hell before I get all fired up over the fact that someone else managed to glue together a bazillion 'killer micros' and win at Linpack...
    Now if someone would bring back the idea of transputers, or we saw some *real* efforts at Dataflow and FP then I'd be excited. I'd love a PC with 8 small, simple, fast, in-order tightly bound cpus. Don't say CELL, all indications are that they will be a *real* PITA to program to get any decent performance out of.

    The 70.72 TF BlueGene/L that debuted on the November list is only 16 of 64 racks of the full machine (25%). BluneGene/L was to be delivered in stages and be a 131072 CPU system when complete (64 racks * 2048 CPUs per rack). The beasty will be well over 200 TF sustained Linpack when it is completed. Oh, and it is binary compatible with System X at Virginia Tech.
  • Whats an applicatoin! New industry standard? :-p
  • ...that by the time Duke Nukem Forever launches, this will be the level of computing power on every desktop? I can hardly wait for Windows mean-time-to-failure to be measured in femtoseconds.
  • Applying the AC relevancy converter, and we get:
