Mister mage, I know you have your own distro of Linux which acts as a router and auto-installs a small linux installation into the folders' memory, so you can save yourself harddrives. It also stores the folding data on the main system itself, so you don't lose ur work in the event of an outage...I'd love to use it, but my need for wireless keeps me from being able to do this.

My question is, would this be possible to port into DD-WRT somehow? It's an opensource linux distro for Linksys routers that turns it into a fully functional server (heck, I can even SSH into my router :D). You could use Samba to mount shares off of a seperate machine to store the folding work, and be able to run a harddrive-less farm and still have wireless.

http://www.dd-wrt.com/

Not sure if it's possible, but it's at least worth lookin' into. At least, whenever you come back that is. :p

Full Folding Ahead!

 
mage is on vaction :D

He will be back later tonight.
Please leave your name and PM after the tone and he might get back to ya

 
Are you asking to run FAH on a WRT? It uses a MIPS CPU and there is no client from stanford for that proc. Besides, it's only 200MHz and it would almost certainly overheat without modding the router, if a client existed.

They are great routers, but don't expect to ever see them folding. Besides, there is only 16MB of ram onboard, unless you have a WRT54GS, which has 32MB(or a WRT54G v2.2 like I have that has 32MB :)). DD-WRT is a great firmware hack for them though, and I've got it on both of my 54G's.
 
No, not to fold on it, but for it to act as the main server to install the F@H files for your network. Have you read into UM's distro?

Full Folding Ahead!

 
is there even enough memory on a WRT to even think about it?


Keep on Folding!! For the [H]orde!!

Not sure, but considering you can mount samba shares, disk space isn't a problem. I say, where there's a will, there's a way. And if you're going to make a machine a router to setup the folding network, why not just start with a router with linux anyway? :p If it's not possible it's not possible, but it's at least worth a shot, since I need my wireless.

Full Folding Ahead!

LOL...

This is kinda actually a freaky good idea....

Take a router, plug in internet on one end (DCHP grab default), out the back attach you boxen and into farm....
 
If you want to use the fold server and still have wireless, disable DHCP on the router, plug the router into the interface for the farm, but not rather than plugging it in through the internet port, use one of the lan ports on the router. The 4 lan ports function as a switch, with wireless. If DHCP is disabled on the router, but a dhcp server is plugged in to the switch, it'll hand out IPs for both wired and wireless connections.

I'm pretty sure this should work - I have the wireless interface set up the same way for my firewall. Router is being used as wireless switch, dhcp server on the firewall assigns IPs to wireless devices.

This would only work if your wireless nic is able to support PXE... (i haven't played with wireless so I don't know what you can/can't do), but that is the main thing needed with Foldserv

or a floppy drive, or a cd rom to fake the PXE

As Marty pointed out, PXE can be handled in many ways. I am sure that would be the least of the problems.

Yeah. Obviously. I havent played with wireless beyond setting up a separate interface for it on my firewall, so my mother can access the net from her laptop without having wireless compromise the security of my ever so slowly growing data center.
I'd be interested to find out if there are wireless nics that support PXE.. currently in the process of putting up a small garden with mage's server... as soon as I get a switch. And if I can have it booting comps over wireless, it would be much easier to spread comps around the house for heating.

Hey now, Oldbenwannakillamoose and I helped out a bunch breaking that thing in the way back machine. Note to all: 32 meg not enough for a node

So here we go- (not even sure a wireless PXE device exists)

Start a wireless fold server Linksys router model v. 1337. This devices casues all other 802.1x devices to reboot, then net boot from this device and start folding. Strap this device to the hood of your car and drive around the city leaving a mega death borg in your wake. Might be against the ELUA thou, might.
 
That would only work if you reconfigured it so that the machine saved work on its own hard drive... otherwise you would have to drive around every 15 minutes so it could save the current frame :p

Ahhh, ok. While I have several machines folding, I don't use U_m's distro, since they all have hard drives and an OS on them, so I never looked into it.

I'm thinking memory is the big problem, here is the free ram on mine here at work:

Right around 3.5MB free, and all I'm using it for is to route a couple of wifi laptops to our network with DD-WRT. I don't even have samba enabled right now, so I'm not sure how much more memory it would eat up. It may be possible though, just throwing out what there is to work with.
 
^ u_m's anit-foldserv uses a hdd for every computer.

foldserv itself only uses one hard drive on the main server..
 
The old (v.1-v.4) of the WRT54G's had 8MB RAM. The new ones (v.5) only have 2MB RAM, and no longer run Linux.

 
someone log into my fold server and see how much RAM it using... I'm guessing more than 8 mb

You're getting mixed up. They have 16MB ram, and 4MB of flash(think of it as disk space). The new v5's have 8/2 and don't run on linux, and are, esentially useless for this idea. You can find old ones for sale though, as I bought a v2 a couple of weeks ago at Fry's.

Yeah everything on this end seems to working

I want a cluster But I don't have anythign to do with it

Rember back int he day when they made a cluster out of ps2's to show it could be done waiting for the ps3's

now would be a good time to start a ps2 cluster

Well, it's a different arch, and x86 machines always use a ton of ram on startup, even a minimal linux config. Older distros of linux use a lot less ram though, so don't think it's not possible because of this version, which isn't optimized for minimal ram.

I'm sure some stuff could be pull off the fold server, reporting and such things.

Maybe have the first node have a hard drive, off load some stuff there via a share or something

router/fold server
Node 1 w/ hard drive
Node 2-99 PXE only boxen

Hahaha.lol Might violate it a *little*.

First node with a hard drive sounds like a good way. Or maybe do something fancy and notice all the hard drives and autodetect which one to use. Or even use a Samba share from your main machine to save everything on, but then when you reboot the whole farm goes down.

Memory issues - like Sandmanx mentioned, it probably won't use as much memory as x86. And fold-server works fine in 24MB on x86. Look at the "top" from oldbenwa: 50580K buff, 32760K cached means 83340K sitting there doing nothing, and 23MB unused leaves 19980K actually used for processes and stuff. If the machine isn't running FAH or samba (it wouldn't need to, just the nodes) then it's under 16MB easily. Maybe put some network-block swap on the first node along with the saves?

Other than that, I'd be willing to buy WRTs, put firmware on them, and sell them to [H]ers for ubereasy setup. Plug in, fold. Firmware would still be available, for those who have the knowhow, but there'd still be a "marty button".

I like that - culture reference (Staples' easy button) and jab at Marty all in one :p

I'll probably think of more things to add later, but post whatever of this makes sense to you.

Well, the only trouble might be finding older WRT's. Most places are selling the non-moddable v5 now. You can order the WRT54GL(linux..just the new name for v4 routers) for around $75 I think, but who knows how long they will stay around. We better get this idea rolling soon if it's workable in the ram limit.
 
Meh, I already have a flashable router. :cool: And the older versions are easy to find, be it in stores or just from people selling 'em.

Useless info from mine, a v3.

Full Folding Ahead!

 
I'm bumping this to see what Mage's thoughts are, since he never replied.

Full Folding Ahead!

 
It's a great idea. However, I need a device to play with, and I don't really need to buy one for any reason other than this. I may manage to talk myself into it, though ;) I want to get working on fold-server again, and this would help motivate me to get going on that. If someone wants to donate one or something, that's okay with me and I'll return it when I'm done.

Has anyone done customization of firmware with these things, by coincidence? I'm looking into it a little, and it doesn't look too hard, but I'd like to make sure it's possible before I get too far.

 
I don't have any extras, just the one I'm using which I need (which can be seen here. But I'll keep an eye out for any cheap ones that could be used. Perhaps you should start a donation fund? ;) The administration GUI even has a spot for setting up Samba Shares by default, so that could possibly be tweaked to be the storage point for all of the data.

I really want to setup fold server, but I refuse to go without encrypted wireless, plus the fact that the router would be handling it all in Linux is just cool. :cool:

Full Folding Ahead!

 
what you need? check what is running our fold server, I'm not sure of the make/model.

it's at 1.1
 
Marty's isn't a WRT. Anyone else? I can trade a linksys non-wireless BEFSR41, so you won't be completely without a network.
