folding@Home

Posted by: Narcolepsy In: Videogame Reviews

You know what I love more than video games? Using video game consoles for things other than gaming. Whether it’s watching fansubs on a DS or turning an old NES case into a storage box; I love not playing games on game consoles.

Perhaps that’s why I bought a PLAYSTATION 3.

Regardless, the coolest non-game (non-illegal) application in a very long while has been released for the PS3. folding@Home was created by the smarty-pants at Stanford University. It creates a network of PC, Mac, Linux (all two of you), and PS3 users in order to simulate massive amounts of data that will be used for researching diseases such as Alzheimer’s and

FAHUSA
Here is the good ol’ US of A. Notice all the little yellow dots? Those are PS3’s running the simulation data.

FAHEUR
Across the pond is Europe with a decent amount of users folding digital proteins. The PS3 was just recently released in Europe and has been selling like fish and chips.

FAHJAP
However, Japan is barely lit up at all. Except for lights in the megalopolis we call Tokyo and a few in the Osaka/Kyoto area, there seems to be no PLAYSTATION 3 systems running folding@Home.

Now, the image was taken at 11:30 pm Japanese time, which is a peak hour for folding. It’s not like the Japanese don’t know about the program, because it’s a part of the 1.6 update that was released not too long ago.

I have formulated a few reasons for the low (apparently) support of this program. It could be the lack of available PS3 systems. It’s not selling as bad as the 360, but not as good as the Wii or DS. Another reason might be that Japanese consumers don’t want to pay the high cost of electricity that running a PS3 all night would generate. It has been my experience that some Japanese folks don’t like running air conditioning even in August. Finally, there may not be broadband internet beyond the bounds of big cities. However, everywhere I have been in Japan (Tokyo, Osaka, Matsuyama, Kyoto. etc) has had broadband internet in some form or another.

There has to be some logical reason for the discrepancy. Do you have some speculation into the subject? Drop a line in the comments.

Maybe they’re actually playing games? lol…

On a more realistic note, I believe the heat (and noise) put out by these things don’t make it nice to run in one-room apartments during summer.

The whole projects seems really cool to me though - wonder if the Cell processor in the PS3 can process faster than most desktop computers?

Btw, can you do anything else with the PS3 while it’s processing? Like surfing the web or something?

Hmmm, I can’t see the energy consumption as the reason. The PS3 consumes WAY less than any PC doing folding and there is quite a big japanese participation. Broadband not available ??? I almost fell off my chair when laughing op hard.
Do happen to know that there are already 100 Mbit lines available for the public in Japan and an adsl2 line is nothing unusual anymore.

Probably the idea was not pushed as hard in Japan due to a different market strategy or plainly because that marketing tool is not (yet) needed.

Regarding the questions from bakavic:
The cell processor can indeed calculate faster than most cpu’s. Interestingly the client developed for the ATI 1XXX cards is even much faster than the cell BUT there’s the catch. A PC cpu is the most flexible of them all. It can do a variety of calculations but at a slower speed. The GPU (graphics) client is lightning fast but it lacks almost any and all flexibility. It can only be used for a very narrow type of calculation.
The PS3’s cell core is somewhere in the middle - not as fast as the GPU and less flexible than the CPU.

You can’t do anything else on the PS3 while you are folding. The client is a standalone application that really uses all resources. If you want to use the PS3 for anything else, you need to stop the folding first. You can set folding to automatically start if the console is left idle for a time.
Highlight folding on the PS3 menu and press Triangle to bring up the menu to set automatic start, then select how long to wait if idle before starting (Off, 10 Minutes, 20 Minutes, etc)

Hope that clarified some issues.

  • Ultrakid: Maybe Tatsuya Fujiwara and Erika Toda didn't look like there anime counterparts but I thought they were good and the director is actually pretty popul
  • Caitlin: This series was one of the funniest I've seen in a long time and I plan on getting it after the release it in both parts.
  • Caitlin: I've had rice with chestnuts and man, that thing sticks like peanut butter! I imagine that 3 dry, rough textures would send me running for some water
