Supercomputer Breaks the $100/GFLOPS Barrier
Posted by CowboyNeal on Saturday August 23, @10:21AM
from the new-kid-in-town dept.
Hank Dietz writes "At the University of Kentucky, KASY0, a Linux cluster of 128+4 AMD Athlon XP 2600+ nodes, achieved 471 GFLOPS on 32-bit HPL. At a cost of less than $39,500, that makes it the first supercomputer to break $100/GFLOPS. It also is the new record holder for POV-Ray 3.5 render speed. The reason this 'Beowulf' is so cost-effective is a new network architecture that achieves high performance using standard hardware: the asymmetric Sparse Flat Neighborhood Network (SFNN)." Because this was a university project, KASY0 was assembled entirely by unversity students, which while being a source of cheap labor, is also a good way to get a lot of students of involved in a great project.

      but super computers as in giant iron are becoming more specialized and as such would woop the pants off a Beowulf cluster when competing in the specialty.

      of course, if you just need a lot of general purpose super computing, it is obvious that you cannot compete with this.

            Really, it's a spectrum. One one end you have fully commodity beowulf, in the middle, you see things like Dolphin and Myrinet, and on the high end you see fully custom backplanes and sometimes RAM and I/O controllers as well. Purpose built CPUs are becomming less common now, but not unheard of.

            Each step up the spectrum widens the domain of problems that the machine can work on efficiently, and raises the price for the machine. In many cases, a 'real' supercomputer is more or less a cluster with a specialized network and OS and mounted in a single cabinet so it doesn't look like a cluster.

            In general when a lower end machine can efficiently run your program, there is no benefit to using a more expensive machine.

            As server hardware improves and 'exotic' hardware becomes more mainstream, the gap between the low and the high end narrows. There will probably always be a small but existant set of problems that call for the 'real' supercomputer, but that set is shrinking.

            There are other considerations as well. If the Beowulf in your lab can solve the problem in 1 week and is available now, while the 'real' supercomputer on the other campus can solve it in 4 hours and will have a timeslot available in 2 weeks, the Beowulf is 'faster' from your point of view.

I remember standing by the cluster looking at all the wiring and being bombarded by an overhead cooling vent. I'm also assuming that these cooling issues is the reason that each case has two blow-holes. I'd also like to see these guys post in-depth specs of each machine. Being a hardware nut, I'd like to see how they got so many machines so cheap, and maybe even what vender they used. As I remember, they worked REALLY hard on their last cluster to keep costs to an absolute minimum.

                    At the risk of being flamebait- No. Using university students is almost always purely a way of getting cheap labor to do semi-mindless, or completely mindless, stuff the staff doesn't want to do- it's a common myth that students 'learn' by doing grunt work. I should know- I have several grad student friends, and they've thusfar spent a large part of their academic careers working in labs doing mind-numbingly boring stuff(according to them.)

                    Imagine if a Bio lab did this. The following would sound pretty absurd: "Help us move our lab, you'll learn about cellular recombination!". No. You'll learn what a bunch of lab equipment looks like, how eccentric the professors are, and how expensive/fragile/heavy the equipment is, and the next morning what sore muscles are like. Let's get a reality check here.

                    (from the site):Our group develops the systems technology for cluster supercomputing; the more people we can show how to apply these technologies, the better.

                    Huh? What cluster supercomputing "technology" does assembling a PC and plugging it into ethernet teach you? Did they give a presentation about how clustering technology works, for example? Did they explain to each person, as they put a machine in a particular place and wired it to a particular switch, WHY it was going there etc? Obviously I wasn't there, so perhaps someone from the group can contribute on this point.

                      Having worked there, and knowing what Hank Dietz and his students are doing, I can tell you that it is different from just slapping PCs together, stringing wire between them and installing clustering software.

                      Dietz specializes in networking and all the wiring that you see in the photos is charted out by custom software that he's written just for this purpose.

                      He works in the realm of optimizing communications among the nodes to avoid network latency and so on. If you read the POVRay benchmarks, you'll notice that the author comments that several clusters' CPUs spend most of their time idle due to network latency. Dietz is researching the best ways to eliminate much of that latency so that the CPUs in the cluster can spend more of their time crunching data rather than just throwing off heat. To my knowledge, he is succeeding at this and better than most other researchers in the field.

                      As for what his students learned from this, I don't know exactly which students helped him on this. For KLAT2, there were several undergrad volunteers who helped with wiring and assembly, mostly from the campus Linux Users' Group. I know his grad students and research assistants are learning a lot about how clustering and network tech works, and a couple are doing their Ph.D. disserts in this very subfield of E.E.

                            Why are not DSPs used in configurations such as this. The TI 67xx series are able to perform about 1 GFLOP/s running at only 150 MHz and cost only about $40 per chip.

                            This price/performance ratio seems to make them very attractive compared to general purpose CPUs. According to the NASA G5 Study [cox.net], the P4 2.66 GHz is only able to achieve 255 MFLOP/s. And the P4 costs about 4x the price of the 6711 DSP.

                            It seems that DSPs should be the clear winner in supercomputer applications, what are their disadvantages and why are they not used? Granted there is a lack of mass produced hardware such as motherboards for DSPs, but that alone should not exclude them from the supercomputer realm.

                                  Actually, they do, but they are referred to as vector processors rather than DSP's. Probably the most famous and the first was the Cray supercomputer [cray-cyber.org]. And there was also the INMOS "Transputer" [ox.ac.uk]

                                  DSP's are optimised to handle streamed data of a particular maximum size (Eg. 4-element float point variables). Useful for image processing (red,green,blue,alpha) and 3D graphics(XYZW), but if you're modelling something like ocean currents, global weather, every data element is more than likely going to have more than four variables (eg. temperature, humidity, velocity, pressure, salinity, ground temperature), you may not get full optimisation.

                                  Plus, you also need a means of getting all these processors to talk to each other. DSP's are nearly always optimised to operate in single pipelines, so don't need much communication support (eg. Sony Playstation 2). However, if you're designing a supercomputer system, the major bottleneck is the communication between processors (network topology). Some applications might only need adjacent processors to talk to each other (global weather simulation usually represents the atmosphere as a single large block of air, with sub-blocks assigned to seperate processors. Other applications might assign individual processors to different tasks, which complete at different rates (eg. the Mandelbrot set). A configurable network architecture allows the system to be used for many more different applications.

                                    Am I missing something? They say:

                                    KASY0 nodes are completely diskless; there isn't even a floppy. (from the FAQ [aggregate.org])

                                    So how are the nodes booted? Are there bioses out there that can netboot?

                                    Not to downplay the fantastic accomplishment, but there is nothing new about this network architecture. Not topologically, as Dietz has been claiming for years now. When did a mix of full and partial mesh suddenly become new?

                                    It's not the first time that these folks in KY work around the definition of the acronym "Flop". A Flop is a floating point operation on 64 bits, not 32 bits. All entries in the Top500 used results with 64 bits HPL, nobody else in the world is running HPL on 32 bits. So claiming the moon on 32 bits is easy, useless for the sake of comparaison and almost unethical. I cannot believe that Dr Dietz do not know the difference by now.

                                    The same machine would yield average results on 64 bits. Difficult to draw attention without headline numbers...

                                      Looking at the specs I'm curious if anyone thought of overclocking the machines to get an even bigger performance increase. It seems that with most Athlons you can get at least a good 100 mhz of extra speed, even with a stock cooler, by increasing the fsb/multiplier and not even touching the voltage. Even a modest increase like that would yield an extra 12.8GHz of power, dropping that price figure even further. Depending on what type of computing they're doing, increasing the fsb might have an even bigger effect than more GHz

                                      Granted there might be some heat problems, but judging by their setup, I'm guessing the room is well-cooled.

                                          You have to include a people time, building overhead etc. A reserach grant may be billing $500 - $1000 a day for this. If this takes 50 man days to set up, then the cost is is another $50,000.
