          Still it sounds like a fallacy. A program (A) is pushed to happen using a certain budget, but a group of people want the money to be spent on another program (B). However, the program (A) continues and its result (C) is a success. Now, a program (D) is being pushed to happen, it does not guarantee a similar result (success) because 1)program D is not the same as program A, 2)the group of people involved in these events are different, and 3)the periods when both events occur are different.

          Not that I against the idea, but I would prefer to see a different way of spending money seeing how India poverty is. However, if they think that pride can make their stomach full, then be it.

      Wait Mr. GeekWithAKnife. I don't know who you are but this is worst insightful text one could type for this post. First delete your impression about India in your mind If(you==Indian){ I feel sorry about the fact that you didn't have clear idea about your nation.} else{ Don't judge India by movies. Visit India and live there and then see what is actually happening there. } Note:It is not the land of homeless people (There are lot of homeless in US but not in Canada). In India, there are about one third of the population who are in poverty. I accept that. But it doesn't mean that government has to keep pushing them up. Those are a third of population who never come up in life even if they are given options. Comparing the policies in India, policies in US doesn't seem quite fascinating to me.(I always had an impression that US would be much better in all terms when compared with India. But it is not as fascinating as it sounds like. There might be lot of things that great happening here). I have seen lot of comments that say like India should focus on poverty rather than these scientific experiments. What do u guys think you are? Marx? for record: I was born and brought up in India and came to US for my grad school (assuming that I can't make into prestigious institute in India. You know why I can't make to those institute bcoz of my caste. It is not easy like here. I have the highest gpa in univ but I can't continue bcoz they are giving opportunities to poor people than me. I did my undergraduate in scholarship and continuing my phd also in scholarship. ) I am successful in my career. I am competitive and very successful than I thought. The same poverty hits me and I am not rich. It's all how you think about yourself. It doesn't have to deal with any country. I had very strong conviction towards my goal. I came to US just because I thought I can do some research. If there is a supercomputer faster than sequoia that going to be there, I bet I will return. so does all Indians. Hope you heard of brain drain and brain gain. Soon that will be the case! P.S: I highly condemn this kind of comments like giving suggesstions that are merely stupid and never appreciating any effort by India.

    Considering Moore's law that's just about to be expected.

    In 5 years we have 3 x 18 month period. The level of improvement in hardware is multiplies by 2^3. Then I'd expect level of parallelism to affect the process by the same magnitude bringing the total to 2^6 = 64.

      Parallelism is usually an obstacle to be worked around, not a bonus, in computers. I suspect the extra 2^3 comes from the current 1st place probably being a few years old already.

        For supercomputing, parallelism is not a problem, since you have multiple data sets from different sources being fed into the computer, and being worked on independently by different CPUs. So the problem one has while writing OSs or applications - making them multithreaded or multiprocessed - is not so much of a problem here, simply given the sheer amount of data that has to be grinded.

      Except Moore's Law only indirectly applies. All it states is that the number of transistors you can squeeze doubles every 18 months or so.

      Number of transistors only really is a passing indication of CPU power. Especially these days where the thing limiting the density of transistors is wiring them up - the "random logic" of a CPU is dominated by the wires that interconnect them together.

      Moore's Law does however apply to the most transistor dense logic aorund - memory. Memory arrays (volatile and non-volatile) are basically controlled by how close you can pack them together, so every generation you can pack twice as much for twice the storage or make 'em half the price.

      Sorry, but you're milking the cow twice: process shrinks allow us to pack more transistors on a chip. This would amount to a growth of about 2^3 = 8 in a period of 5 years, as you correctly estimate. But this already includes the increase in parallelism. Today's supercomputers apparently don't grow much more racks:
      • Roadrunner: 296 racks
      • Jaguar: 150 racks IIRC
      • K computer: 768 racks (huge exception)
      • Sequoia (Blue Gene/Q): 96 racks

      The reason why we can't just buy an infinite amount of racks and network them is the MTBF [wikipedia.org]. In the K computer the MTBF means that node failures occur every couple of hours, rendering longer full system runs almost impossible.

    How well do the 'fastness' metrics used to rank computers in e-peen order capture some of the messier variables of assorted cache speeds and sizes, latencies and throughputs of network interconnects, dubiously general; but very high speed for certain purposes GPU or fpga elements vs. generic CPUs, and so on?

    Obviously, the people building these things to get work done have an incentive to make them actually useful; but is the benchmark itself much of a test of dreadful interconnect design or other serious issues, or could you just buy your way to a shiny spot at the top by shoving together enough gigE connected 1Us?

    • by serviscope_minor ( 664417 ) on Monday September 17, 2012 @12:28PM (#41363841) Journal

      Depends on the test.

      The classic LINPACK benchmark will stress most of the parts which will mean the result is a combination of raw FLOPS with memory bandwidth, cache and etc. LINPACK doesn't stress the interconnects particularly highly and is very regular. As a result, it tends to favour computers that have more FLOPS but cheaper interconnets.

      That said, it's not terrible, which is why the computers also have the efficiency (theoretical peak FLOPS/actual flops) listed. Compare the Tinhae-1A computer which was heavy on GPUs versus with 46% efficiency the K computer which has lots of wide SIMD cores with a very tightly coupled interconnect which achieved 93%.

      So even LINPACK which is generally considered as "too easy to be a useful test" still can distinguish between raw peak FLOPS and sustained performance.

      In practice, some tasks will depend heavily on the interconnect. Others, like protein folding are so embarressingly parallel that the interconnect basically a non-issue which is why floding@home works.

      IOW YMMV HTH HAND

      More importantly, what do these supercomputers do? i love computers as much as the next guy (or gal) on slashdot, but i'm unaware of anything that they do. they don't seem to be involved in landing robots on mars. they don't seem to be involved in making a self driving car. I guess they will do environmental simulations and then show you the results you want after you tweak the input data enough. Oh, and they can win at jeopardy and chess.

        Modeling.

        Weather modeling (solving navier-stokes and a few other equations on a discrete cartesian grid or on a spherical grid in spectral space). Add in land surface models, ocean models, data assimilation, chemical processes, and then crank the resolution way up and you need a lot of power.

        DNS (direct numerical simulation) -- if you want to simulate a fluid flow with turbulence and you want to resolve the turbulence explicitly you need to have a grid spacing in your model that is smaller than the kolmogorov scale. For some flows this may produce a grid spacing measured in millimeters. If you want any decent sized model domain, this produces a lot of grid points.

        Monte-carlo type simulations -- i.e., run a simple simulation but do it 1e50 times to amass a statistical representation of the process.

        and lots of other types of modeling. Basically if you have a set of partial differential equations that tell us something and you need to solve them numerically (no analytic solutions, etc) and need to do it on very large domains at high resolution and your neighbor grid dependencies are such that your problem is parallel, then a supercomputer is for you.

        They model protein folding, cosmic events such as the big bang, creation of black holes, stellar collapse and creation,they are used in modeling atomic bomb blasts, and better electrical grids, they are used to work out highly complex math and number crunching such as finding holes in encryption schems, they are used for analyisis of high speed partical excelerator data. Pretty much anything that requires lots of compex math.

        * The weather report
        * Finding oil and gas
        * Supernova research
        * Big bang simulations
        * Designing rockets for the space program
        * Simulating nuclear fusion

        In general, solving large problems where there is turbulence, other complicated phenomena or the data set is hard to search

        They are, in fact, used for landing robots on Mars. I worked on a supercomputer with my professor during my physics undergrad working on fluid-structure-interaction (FSI) code. The supersonic parachute used to land Curiosity was simulated using a FSI code, a simulation which my professor helped with. Cars these days often use fluid dynamics during the design process and structure code as well (which can be just as complicated when you're simulating a collision, as is often done these days).

        There's really a lot of room for processing power and memory growth... Just think about it. If I want to halve the grid spacing, I generally have to double the number of points (or elements) in each dimension, plus I have to generally halve my timestep as well (for numerical stability). So, for every halving of the grid spacing, I need 16 times the processing power and at least 8 times the memory (and 16 times the memory if I want to keep all the timesteps). So, it may take a good 6-10 years between being able to halve your grid spacing (if you include the fact that computers don't scale up in performance--especially at the superconductor level--as fast as Moore's law says you scale in per-transistor cost). And if you're doing a fluid or solids simulation, you usually want as small of a grid spacing as feasible. At this rate, the time between a 1cm grid spacing and a 1mm grid spacing in performance would be 30-40 years, a whole career. And that's assuming Moore's law continues.

      I have read that the Sequoia supercomputer can do 2 Gigaflops per watt, I think this is at least an order of magnitude greater than any home computer. So when they get into the Exaflop range I would think that they would again be better by an order of magnitude. So that would mean they could do 2 Teraflops per watt. My question is what are they going to do with all this power? I would think that the federal government would get a Watson like computer for both the executive and legislative branches. I would think it would run a site where everyone could log on and express their views and get a response based on the beliefs of either the President or an individual congressman. Even today how many programs are based on a computer's output? I am sure that the CBO depends on computers to generate its reports. So how much longer do we rely on the middle man and just rely on the computers?

    India's current supercomputer - one that it's developed since the 80s - is the PARAM [wikipedia.org], which has had 6 generations to date. The first was based on the Inmos Transputer, the second on an Intel i860, the third on a SuperSPARC II (and it even had an Alpha variant), the fourth on an UltraSPARC II, the fifth on an IBM POWER 4, and the most recent - unveiled in 2008 - was based on the Intel Xeon (Tigerton 73xx). They are currently working on one that's supposed to break the 1 petaflop barrier (that would be 10 crore crore flops for Indians). So this new announcement would be the successor to that.

    So it's not like they're new @ this, and what is impressive is that they've used a wide variety of CPUs from different vendors. For this next one, they might want to do that w/ an Itanium III or a POWER7 (unless POWER8 is anywhere close). It would seem that for that, they might get some Intel/HP expertise to help w/ that. I have no idea how good they are @ writing compilers. But yeah, planning a supercomputer based on this CPU and tossing in enough of them should enable them to achieve that goal. Put Debian on it, and then use it for whatever they need - weather forecasting, nuclear simulations or whatever they want to use it for. A lot of the 52 PARAMs that they've manufactured & sold have been sold to other countries.

    I just wish that aside from the Indian government, there were a few companies in India that made supercomputers.

Would you rather have it that they spend much more buying when they can build it locally for cheaper? Also after all the dust of 'they should rather help the poor instead' argument has settled you can see that despite so many issue they still need to predict the weather.

    The politicians in India are talking about investments in space and supercomputers because its sexy and gets people's attention. Whether or not these investments are going to materialize, or if they're even wise, remains to be seen. Perhaps all my fellow Americans will read about an Indian supercomputer one day, while we enjoy the comforts of our future lives on Moonbase Gingrich.

    I hadn't realized that you needed so much computing power to run a call center.
