The Processor Wars

1 Comment

There are many ways to make a profit; one of them is to make a better product than the competition, but sometimes that alone is not enough, especially when you make the components of complex devices like computers. So maybe you could think about building loopholes into your product that make the competition’s product look inferior when used in the same system? There are suggestions that’s what nVidia has been doing:

PhysX is designed to make it easy for developers to add high-quality physics simulation to their games, so that cloth drapes the way it should, balls bounce realistically, and smoke and fragments (mostly from exploding barrels) fly apart in a lifelike manner. In recognition of the fact that game developers, by and large, don’t bother to release PC-only titles anymore, NVIDIA also wisely ported PhysX to the leading game consoles, where it runs quite well on console hardware.

If there’s no NVIDIA GPU in a gamer’s system, PhysX will default to running on the CPU, but it doesn’t run very well there. You might think that the CPU’s performance deficit is due simply to the fact that GPUs are far superior at physics emulation, and that the CPU’s poor showing on PhysX is just more evidence that the GPU is really the component best-equipped to give gamers realism.

Some early investigations into PhysX performance showed that the library uses only a single thread when it runs on a CPU. This is a shocker for two reasons. First, the workload is highly parallelizable, so there’s no technical reason for it not to use as many threads as possible; and second, it uses hundreds of threads when it runs on an NVIDIA GPU. So the fact that it runs single-threaded on the CPU is evidence of neglect on NVIDIA’s part at the very least, and possibly malign neglect at that.

Whether it is malign remains to be seen (the use of Occam’s Razor may well apply here, but then again it may not), but this is still an interesting development: in a world where most new inventions are part of larger systems, the battle for sales isn’t simply a matter of making your own product better. Granted, talking down the value of a competitor’s product has been a core strategy of public relations for years, but actually attenuating that value in deployment strikes me as being something pretty new, if only because it wasn’t really possible before. Unless anyone can suggest a situation where this has happened before?

Bacterial biker jackets and after-market parts for people

This year seems like it’ll be the one where the mainstream starts talking about custom-made replacement organs as something more than science fiction. A few weeks back we heard about the rat who got a new set of lab-grown lungs; this week, Wired is running a photo-essay on bioprinting that’s a must-see for anyone who wants to be able to write a plausible description of the working environment of a contemporary Frankenstein.

Meanwhile [via BoingBoing] Ecouterre reports on UK-based designer Suzanne Lee, who’s been using bacteria to grow an entire range of clothing from a rather mundane starting point – sweetened green tea. The end results are made entirely of cellulose, though they look (to me at least) like the skin of something that still slinks through radiation-soaked cities long after the posthumans abandoned Earth for the new terrain at the top of the gravity well…

Organic ain’t yer only option, though, no sir. 3D printing means one-off custom designs of mechanical prosthetic limb can be made for amputees or other folk with different levels of physical ability… and not just for us longpigs, either, as Oscar the cyborg cat ably demonstrates. 3D printing is still an unevenly distributed piece of the future, of course, but it’s spreading fast; Ponoko have just set up their first 3D print hub here in the UK, and if they can afford to do that in the current economic climate, the business model must have something going for it, right?

It’s interesting to see the organic and inorganic racing along in parallel like this; it doesn’t take a genius to see the possibilities of the two streams converging somewhere down the line, though I’d guess that’s a good few decades off from the present day. What’s interesting to me about these phenomena is the way they seem to be an end-game expression of the desire for individuality and customisation; at the moment, price will keep all but those with a serious need for these products out of the market, but as prices fall, everything will become bespoke, unique, a one-off. Which is kind of ironic if you think about it: through the total ubiquity of mechanised manufacture, we’re actually putting an end to mass production.

Walk a mile in another (wo)man’s virtual shoes

3 Comments

I’ve often thought the world would be a fairer place if we could all spend a month living as someone of a different gender, race or level of physical ability. Until the gene-mod folks get us to the level of Iain M Banks’ Culture and provide complete plasticity of embodiment (c’mon, people – get a move on with that!), the next best thing is the Metaverse. New World Notes reports on the experience of a Second Life clothing designer who spent some time in a male avatar:

… Rebecca came away with a lot of insights, besides how to better make male fashion: “I learned that you can’t really trust anyone, male or female,” she tells me now. “People in Second Life can tell the truth as easily as they can tell a lie.”

(Lying about oneself is not exactly a thing unique to SL, but the ability to present visually and conversationally as something you are not adds all sorts of layers of complexity into the equation.)

By being a virtual male, “I learned about some of my own weaknesses at the time, such as my tendency to believe what every male avatar told me, especially if they had a good looking avatar. I think the visual aspect of Second Life somehow tricks the brain into taking our past experiences and cultural expectations and placing these experiences and expectations onto others within Second Life… I think a lot of women have the same type of thinking when they go into Second Life and tend to become attracted to good looking avatars, and overlook the avatars who are not particularly attractive.”

It’s hardly a rigorous feminist interrogation of the SL social space, but there’s some value there nonetheless. It’s interesting to note that Rebecca found herself falling back on the default “player” behaviour of male avatars who’d hit on her in the past; score another point for gender as a social construction.

I really wish more people could be encouraged to try this sort of thing out; most of my own (admittedly shallow) revelations about the actual experience of othering has come from spending time in female avatars, as well as observing the persecution of friends who embody as furries or other anthropomorphs. Nothing brings home the casual (and often unintentional) misogyny and privilege of baseline male behaviour quite like being on the receiving end of it.

Three-course specials at The House Of Longpig

The lines between futurism, architecture and conceptual art continue to blur and fade (if they ever existed anywhere other than our own minds, that is); a chap called Mitchell Joachim is working on making a house from meat. Yes, a house. Made – grown, to be more precise – from in vitro tissue culture. A meat house. House made of meat. [image ganked from INHABITAT]

The In Vitro Habitat... AKA "meat house"

While we’re talking about in vitro meat, Wired UK turned over the mic to Warren Ellis, as they do on a monthly basis, and he decided to talk about cannibalism. Fans of Ellis’ reputation-making series Transmetropolitan will remember that The City was full of places where you could eat pretty much anything, all the way up (or is it down?) to cultured human flesh, and that riff gets echoed here:

… the technology is there to start generating human meat without the dubious ethical intervention of human slaughter. Which is harder than you’d think, and the artificial meat version wouldn’t have any Rohypnol precipitate in its cell structure. If there’s no human shoe-beasts involved in the butchery, where’s the problem? Show me the ethical hurdles to ordering a cultured manburger.

I demand that science do its job and allow us all to indulge in a consumer experiment: are humans the most delicious meat of all? Furthermore, I think there’s an easy way to access more funding for this goal: celebrity cell donation.

Of course, Uncle Warren is being ironic here, and has no real interest in eating human flesh, cultured or otherwise.

Probably.
