Folding @home?

I see that there is a GWJ team already setup for it but no one has done anything.

While looking up at the stats it seems the PS3 has some serious number crunching power, about 10x that of a normal PC. In fact, it's already blown out all the PC's combined.

I have five PC's folding and I haven't much of anything since it takes a while compared to the PS3.

WoW, I haven't done folding in quite a few years. Think I might have to hop on the GWJ team and start putting up some numbers.

I just found this team this morning when I tried to create one and found out it already existed. I just thought I'd mention this again for the new PS3 owners the site has gained lately. It's a worthwhile cause and like Edwin says, the PS3 buries most PCs in terms of how fast it can chew through work units. The team number is 48357. All you have to do is punch that into the utility and you're in.

I suppose my shiny new Quadcore could lend a hand.

I'm all setup and running.

Me too. Only not a Quadcore, you showoff.

It doesn't make for much showing off so far. I start the program, it runs for a while, I leave the computer, and when I come back it's just magically not running anymore. No error message windows leftover or anything. Just gone.

This is happened two of the three times I've fired the program up. Ah well.

What version are you running? Command-line Linux version runs well for me.

My PS3 does crank out the work, appears faster than my dual core 6600 overclocked to 3.2 Ghz. had to stop the PC version though, had the side effect of borking my dvd so i couldn't see any discs, weird.

Thread revival!

Well.. I ended up with a PS3 so whenever I'm not watching a blu-ray it will probably be running the Folding client.

Finished work units here I come.

I'm on my way to the top of our team and ain't no one stoppin' me!

Ok, my floor has 4 PS3's. I'll see what I can do.

You guys know this is how Skynet starts, right? =P

Queue Kataragi: "Connect 100 PS3's together and it becomes self aware!"

NVIDIA: The way you're meant to be nuked!

Has there been any scientific breakthroughs attributed to [email protected] ever since it started in what, year 2000 ?

You know... just curious.

I'm not sure about [email protected] but another project I used to be involved in actually closed because they ran out of data to process. They claimed that research into several subjects had advanced a number of years. Like most long-term research, results are not necessarily immediate but they are still plausible.

Research is never, ever wasted. What happens is that the data, if it doesn't immediately show any use, is archived, and it becomes ... well, sort like fertile ground, from which other discoveries can spring. Later scientists will notice something, and then go back and look at earlier data, and then figure out something cool.

As Asimov said, the most exciting phrase in science isn't "Eureka!", but rather, "Hmm, that's funny."

Just joined, but my PS3 restarts every time I exit [email protected] I googled it and it seems to be a somewhat common problem.

EDIT: I have found the "solution". The PS3 restarts when I exit [email protected] by using the PS button but it exits normally if I use the circle button. Weird.

Yeah, that restarting behavior is by design. When you quit anything with the PS button menu, it just soft resets the system.

I summon the forth from the dead!

After countless hours of work tweaking my first dedicated [email protected] machine is soaring: 100,974.46 PPD atm

I have the parts for a second equivalent rig but I still have to put it together, should be quicker now that I've done it once.

V7 client is finally live.

We have a team? Awesome, I'll be switching over when I upgrade the client later tonight

Finally have it running, I've been meaning to do this for a while.

I learned of the existence of GWJ by seeing it on the Folding @ Home team lists.
