BlueGene/L Puts the Hammer Down

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."

      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?

      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.

Algorithms exist to make this a little faster using approximations and shortcuts, but for the most exact purposes there's a pretty solid limit to how good they are.

      Further, because bond vibration frequencies are fast- think femtoseconds (10^-15 seconds), my own work typically models using no more than a 2fs time between steps- that is, there are 10^12 fs in a millisecond.

    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.

    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.

    Slashdot is still using the 1976 Cray-1 as the icon for supercomputing, and I think its safe to say supercomputing styling has gone down hill since. Not that these things should be like cars, though here at Slashdot we tend to salivate over them like they were. Don't get me started on people who are into case mods.

    I remember seeing a news article on TV recently about NASA and their upgrades to computer horse power for doing flight simulations and design work. The picture they showed? A late 80's connection machine. You know the beast, 8 black cubes glued together to make one big cube with hundreds of blinking LEDs over the faces, one for each of the 65536 simple processors. Sort of a Borg at Christmas time affair. Stock footage to be sure, and the news outlets trot it out every time the word supercomputer is used. At least they've quit showing IBM Model 726 Tape Units spinning reel-to-reel tapes back and forth as a show of awesome computing power.

      Thinking Machines had a parallel processing computer with hundreds of blinking LEDs. It appeared in a documentary about Richard P Feynman. He helped go through the Boolean Logic and reduce the number of logic gates required for the various circuits or something like that..

      Thinking Machine Corp (TMC) had the best blinking lights ever. You were describing the CM-2:

      The machine was a massive SIMD processor. It didn't have one light per CPU, but one light per 16 or 32 (or was it 64?) CPUs. Depending on the setup, the light was on if the group of processors it represented was active.

      Their other machine, the CM-5 also looked way cool:

      I still think the CM-2 is more 'space age' and I think it was better looking.

      The Cray1/XMP/YMP was also a great looking box, even though it had no blinking lights. The benches were warm, becasue that's where the power supplies were housed, and even though it wasn't exactly comfortable, you could take a nap on it.

  42. Try doing it yourself by Anonymous Coward · · Score: 0

    Yes, all applications may be improved.. to a point. But the simple fact is that when you are trying to simulate a system where you must track billions of individual data points, you must have a good deal of processing power to do it in anywhere close to a reasonable time.

    Ex: Simulating a nuclear blast over a person. The requirement of the system is to track each cell in the person. And you are tracking it at the nano-second level. This problem cannot be optimized away.
