Folding@Home Cluster

post #1 of 10
Thread Starter 
For fun/because i can i want to get a bunch of old pcs, make one a hub, put linux on it, network boot a bunch of other old pcs, and fold on it. I want it to think its one computer. They are old pcs so to run the smp client im gonna have to use wine and the windows client. How would i go about setting this up. I know i need a big ass router, lots of network cables, and a bunch of pcs. I really need help on the software side, mainly setting up the controling pc/all the clients, picking the right linux, setting up network boot, and setting up the client correctly so it recognizes all cores in the "cluster"

here is a quick 5 min sketchup model of what im thinking of. Of course there would be ethernet cables from all of the mobo's to the switch and a mointor, keyboard and mouse connect to one of them.

won't work - the latencies are way too high to run F@H like this. Your PPD would be terrible, your power bill would be through the roof and you'd be tearing your hair out...

I think he's talking about loading an OS completely into ram from a network share rather than using network disks as the hard drives, kinda like a live CD. If that's the case then it has been done before. OP, you may want to check out this link.

That isn't what his post says - he wants a cluster with all the machines acting like a single computer. Which doesn't suit folding at all.

That's because doing what he wants to do won't work how he wants to do it. He'll be amazingly lucky if he manages to get 100ppd/node, yet will be running 100W/node. For a 10 node system he might break 1000ppd (if he's got decent kit) at a cost of 1kW power consumption - and that's roughly the amount of folding that a $30, 30W NVidia G 210 can do. Even running the systems separately he'd get 300ppd/node or so, as by the sound of things none of these systems would be capable of running the SMP client by themselves.

Best bet OP. Get a load of SB's and run a seperate SMP client on each.

I agree

OP... i inquired about this before.

Check that out for a load a let down. I wondered the same as you.

This is what I had pictured in my mind when I started building my multi-smp rig. Now I've ended up with a giant 50U+ 2 post telco server rack with huge freaking ATX server cases and various networking gears. God bless overkill. Might still scrap it all eventually and build something to look more like that. But on topic I do remember reading somewhere that the FAH team said that basically we're already all nodes in a giant cluster so adding on smaller clusters like what you'd want to do won't work correctly. Maybe Zodac said that. I don't recall now. It's science.
