  1. Recommendations vs. Requirements on Hardware Manufacturers Making PC Gaming Too Elite? · · Score: 3, Interesting
    I knew somebody my freshman year of college that was on the invite list to the big Quake 3 tournaments, was rated somewhere in the top 100 in the country, and was overall amazing at the game.

    Guess what he played the game on? Some crappy 8 or 16MB video card with all textures, details, resolution, and everything else all the way down. He had sound through what can only be described as a $2 pair of speakers, but they were enough for him to locate people (which was plain scary). The processor in the box wasn't anything spectacular either. He managed somewhere around 50-60 fps on that thing.

    Quake 3 looks terrible at 640x480 with no detail, but it is perfectly playable. Heck, it's even fun multiplayer, because the gameplay is the same, it just isn't so pretty. But it doesn't have to be pretty to be fun. Pac-Man is fun and the graphics on that are terrible. I'm going to guess that Doom 3 will be perfectly playable on minimum specs as well, probably just not as pretty. Also, a $70 GeForce FX 5200 is a DX9 card last I checked. If you want the highest available resolution and textures and want the game for it's glitter then yes, you'll have to shell out cash for it.

    That's the way its always been when you want the best right when it's released. I know people who bought a bunch of RAM to play Wolf 3D or Doom or whichever without windowing to a 3" box. You could, however play it in that 3" box. And those RAM upgrades were spendy. Sure, it helped the rest of the system, but when the box was games primarily and other things secondary it hardly matters. Cutting edge has always been expensive.

    Fully agreed. I was more pointing out to the original poster that Pixar's task was about as good as it gets when it comes to parallelization, and that nobody needed to call Pixar up and tell them anything about their speedup.

    In my explanation I failed to point out that the big point where HPC is going to pull ahead of cheap off the shelf clusters is in the message passing. To my credit I at least mentioned the insane interconnects like Myrinet and do know that fast data passing is a large part of the battle.

    Pixar lucked out that the data passing can be hidden during the rendering of the first frame and the only transfer cost their cluster will ever see while not working on the problem is the transfer of the first frame.

    And yeah, Cray is really going about their statements wrong. It isn't the linux portion at all, but really the underlying hardware.

    Yup, I goofed on the point to pick apart there. The interconnects (which I also touched on) are probably what Cray was taking the linux machines to task on. Pixar's problem is ideal from the standpoint of not having much communication involved in the parallelization of their problem too. It's truly about as good as you can get.

    If there's a lot of message passing that's likely to be the point where Crays shine, since the article mentioned something about obscene processor level interconnects.

    I guess I got caught up in the point that the original poster was making about how Pixar magically got great speedup out of their clusters and pointed out more that it was the problem than focusing on how a problem might favor a Cray rather than a cluster. Thanks for pointing it out.

  4. Re:Proof: All problems can be computed in parallel on Cray CTO: Linux clusters don't play in HPC · · Score: 1
    Well, it's been a little bit since my Parallel Computing class, but here goes for a problem which you would not want to compute in parallel.

    The problem is simple, seed a random number generator with the processor id number and sum up the first N numbers generated from that seed, where N is the number of computers in the cluster. Why are we doing this? I have no idea, it's just my example problem.

    If you want to do this in parallel you have to grab the seed from the machine which is initiating the problem, as the seed is tied to its processor. Then you have to scatter that seed. Then each node in the cluster has to generate M random numbers from that seed where M is the computer number of that node in the N node cluster. Then we can gather the values, adding the values that are gathered each step of the gathering for (lg N) time of actual addition. The scatter and gather also take about (lg N) time if you consider the transfer to be on the same order of time as an addition (if I remember right...). At this point we're looking good. Sadly, remember there are N operations for the last node in the cluster to get the Nth number from the random stream. O(3 lg N) + O(N) is on the order of O(N)

    Now consider doing this on a single machine. N operations to get the full set of numbers to add plus N-1 additions is O(N). There is zero speedup by doing this in parallel. If you consider that data transfer is hardly on the same time scale as computation (maybe with uber-expensive interconnects, maybe) then you're actually wasting time by sending the problem through the cluster, resulting in a slowdown rather than a speedup. I suppose you can argue that it's parallelizable, but I'd call anybody who wanted to do this in parallel a fool. No matter how you split it, some machine will be forced to do N operations to get the last number out of the stream.

    I'll grant you that the example is contrived. However it clearly shows that there exists a problem which cannot be sped up by being run in parallel. It is by no means a stretch to think that there are interesting problems that rarely see a speedup of over 8% when run on a cluster.

    Pixar doesn't need telling, their problem breaks up so miraculously well that they'll see the best performance you could possibly expect from a cluster. The big problem, rendering a movie, decomposes into thousands of small problems, rendering a frame. Each machine in their cluster can handle a group of frames at a time with zero need to communicate or worse, share computation, with other machines in the cluster. It's the best case scenario.

    Many other computing problems don't decompose nearly so nicely. So there are certainly problems that probably won't see more than 8% of peak performance. If you were particularly inclined you could probably invent a problem that had to be done serially, leaving percent of peak performance equal to what percent of your cluster one box was. Cray is right to that extent and if you're solving a problem that falls into the category of not easily parallelized then perhaps one of their machines is the better tool for the job. But, like you mention there are instances where the cluster is a great tool and cost effective to boot.

    Heck, ever check out some of the faster interconnects like Myrinet? They're insane and exist because fast ethernet just doesn't cut it in some places. Just using a slow interconnect is enough to bring real performance down below theoretical peak. Luckily for Pixar off the shelf fast or gigabit ethernet is likely enough.

    Anyway, use the best tool available. If your problem falls into the category of trivially parallelizable like rendering a movie is then don't bother wasting your money on a Cray. If your problem isn't suited to a cluster, however, then maybe a cluster isn't the right answer. If you have a big problem that needs serious computation take the time to figure out what you need before taking a marketing drone's spiel for gospel in your situation.

    No, while Sim-city is a game it is an incredibly well done game. The reason that people feel this urge to make comments and references to Sim-city is that the game is well enough balanced that it feels like things should work the way they do in the game.

    Yeah, things are a tad unrealistic in parts, like $10 for a segment of road or the $15,000 desalination plant. But the balance from income to expense and the balance of population needs vs. budget are well done. I have a hunch that Maxis keeps the costs way down so people don't get intimidated about multi-million dollar budgets every year and instead get excited when there are tens of thousands of dollars flowing in and out of their coffers in a given month. Just a guess though. I don't think anybody that plays the game realistically believes that a coal power plant costs $10,000 or that they can buy 1,000 MW from a nearby city for $20 a month. However, the concept that relying on your neighbors for power means they will raise prices is pretty universal.

    Or, if that doesn't sate your rabid urge to scream "It's a game!" then I'll just bother to remind you that the comments referencing Sim-City are jokes. Jokes are all.

    In sim-city you have to provide basic necessities to your sim-residents, or they never move in, move in low density and low revenue buildings, or just move out if you stop supplying them. One of the things that you have to provide is water.

    One of the nice features is that you can buy things like water and electricity from your neighboring cities for a price. This price tends to be higher per unit of supply than you could provide with a structure like a power plant or water pump, but requires far less up front cost. The not so nice thing is that your neighbors will occassionally renegotiate the price with you, meaning you'll pay more each month if you want to continue getting these supplies.

    The joke in the previous post is based on the fact that you could import water (based on the bottled water comment) or that you could build a costly desalination plant (as the article suggests is happening). In sim-city you'll get shafted in time if you don't provide your own facilities, thus the neighbors raising the cost of bottled water is funny.

    Now I feel like one of those people that analyzes a joke until it isn't funny. However, I went to the trouble of explaining for the poor non-sim-city player so I'm just going to post it... blah. The interesting thing is that bottled water seems to be pretty expensive anyway, and building one of these big plants is probably well worth the trouble in the long run.

Double Dash seems neat, but I'm getting really sick of cart games. They're all practically the same with one or two little twists and what I find to be poor control.

    Anyway, you're right, Nintendo is second worldwide. I keep forgetting that the Japanese seem to hate the xbox with a passion. They're behind in the US though, which isn't a good position for them. And if I recall, the race is fairly close, especially considering the gap to the PS2 sales figure. Demand has certainly shot up with the reduction in price again, which is great. The new titles coming out for the cube have it looking good as well.

    As for buying which console now I'm still going to speculate that having more cubes in geeks hands would be better. Apart from the people who pirate massively or turn the xbox into a media box of sorts, the geeks are going to want something out of their investment aside from a 10 GB drive that's a pain to unlock, a celeron, some ram, and an inperceptable dent in MS's budget. While some might sit it on a shelf, others would certainly give in to the temptation to play it.

    I'm not against buying the xbox and playing it as a console. I think it's an interesting approach and the games are generally well rendered. But I think if you're going out to hurt Microsoft then helping their enemies will be the best route. Even without backwards compatability Microsoft can lure good developers with better sales figures. Developing for the US market? Then MS might be a better option than Nintendo. Buying up Xboxes only strengthens that claim.

    Beyond that, I've never been convinced that backwards compatability sells consoles. Honestly I got a PS2 for PS2 games and the backwards compatability has been relatively unused. If I had a huge PS1 library I'd have a PS1. Now I doubt I'll get a PS3 since the PS4 will almost have to be backwards compatable, so Sony's pretty much lost a sale for being backwards compatable. If the Xbox 2 were backwards compatable I might hold off a purchase of one for the second console, again, losing a sale. But if not then no big loss because I can pick up an xbox on the cheap later if I really want it. I can then choose my next console for the next gen hardware. I never expected backwards compatability with my cartridge systems and it never mattered then. Why should it now?

Or if you can't stand the thought of waiting 5 whole months buying only greatest hits games you've underlooked because you have to have every game first, then take $25 each month and buy a new release every other month. It'll take 6 months of that. Simple budgeting.

    As an alternate suggestion you could save everything 3 months straight and then buy a couple greatest hits games for the new console the next month, which you know you've been wanting. Then buy three in the second month. Then go back to new releases. If something big comes up after the 3 months then you can get it instead of greatest hits games, you've still got $50 a month. If it happens in the first 3 months just delay the console purchase. This isn't hard.
