making a cheap but powerhouse W.C.G. server farm at home?

Hi all,

I have recently discovered Dell's Wyse series of Cloud Client Computers. (http://www.dell.com/us/business/p/cloud-client-computing & http://en.wikipedia.org/wiki/Dell_Wyse) I have never heard of this before, but it seems this could be a sweet way to contribute a lot to World Community Grid at minimal cost to myself. But seeing as how this is an entirely new concept to me, I need to be sure of some things before I even consider purchasing one or more. I have no use for these Wyse things, so if I bought any, they would be entirely dedicated to W.C.G. tasks.

(1) First off is the general question: isn't W.C.G. the kind of work that "thin clients" are MADE for? Sure seems like it, just checking... if I also would need to buy a Client Manager, that makes this less attractive.

(2) These Wyse boxes come with several different flavors of operating systems: Wyse ThinOS, various flavors of Windows Embedded, various flavors of Linux, Windows XPe, Windows 2009. I know Windows obviously, I have a working knowledge of command-line UNIX, and I've never used a GUI front-end to Linux but I suspect I would enjoy that. Any advice here? Mainly, do any of these clearly not support a W.C.G. client and must be avoided?

(3) Now, I'm assuming that with these "thin clients," I might need some device that acts as "manager," correct? http://www.dell.com/us/business/p/cloud-client-computing They make client managers, device managers, and who knows what else? The root question is if I could just buy one thin client and easily set it up to run W.C.G. tasks day in and day out?

(4) Then I was also concerned about making a new fire hazard in my studio apartment. I asked an I.T. manager about that and he replied "Fire risk is minimal. If you live in a modern dwelling your circuit breaker will cut you power before trouble.. A 15amp circuit can handle about 1800w." Any comments as to whether or not that holds true?

(5) Finally I was concerned about a significant increase in my power bill. The same I.T. manager says "if you ran 5 computers with 100w power supplies around the clock you would spend about 500w*24hours/day*30days/mo/1000*0.1$/kwh =$36 per month." The Dell Wyse C class thin clients boast an average power consumption of under 7 watts. (http://www.dell.com/us/business/p/wyse-c-class/pd?~ck=anav) So would this be right then-- one of these then clients not 5 computers, so divide by 5; then 7 watts instead of 100, so multiply by 7 hundredths or 0.07... leaving 36 / 5 * 0.07 = 50 cents a month to run each one of these???

So to wrap up, I'm looking to cheaply and easily make a home server farm for the Grid. What am I looking at for my total projected cost? (I've seen Wyse boxes on eBay for $20 that are used, but Best Buy sells some brand new for $100; hmmm...)

Thanks everybody for any and all constructive input!
Jeff
oh, p.s. is anybody already using these for World Community Grid?

Re: making a cheap but powerhouse W.C.G. server farm at home?

I'm not sure this makes a lot of sense. These processors only run at 1ghz. You could get a used i7-2600k running stock at 3.4ghz with 8 threads. That would be equivalent to 27 of these machines or more (3.4 x 8).

And the total amount of electricity for running that many machines would be almost 200 watts - which is probably a lot more than what an i7-2600k rig would draw since its TDP is only 95watts.

Plus a used 2600k on ebay is only around $200. You're probably going to pay twice that in shipping for 27 machines.

And all this is assuming that 3.4 single core Via Eden chips running at 1ghz is equivalent to a single thread on a 2600k, which I wouldn't want to bet on until I saw some stats.

Re: making a cheap but powerhouse W.C.G. server farm at home?

Hi Jeff,

Looks to me like these are made to work with a virtual desktop infrastructure (VDI) ($$$). In the promotional materials, they refer to "cloud client computers" which means that the real processing takes place out in the cloud or stated another way on a virtual desktop infrastructure. The thin client is just an interface to the virtual desktop that exists on the virtual desktop infrastructure (which usually includes VMware or Citrix). If you notice on the technical specifications, there is no hard drive space listed. That is because all data is supposed to be stored out in the cloud (on the virtual desktop infrastructure). Also notice that the operating systems on the thin client Wyse devices are listed as "Windows Embedded Standard 7" etc. An embedded operating system is not the same as a regular desktop operating system. I would be surprise if you could get BOINC to function on a stand alone thin client device.

If you really wanted to go with a low power processor, VIA makes a motherboard that is about the size of a credit card and uses mainstream operating systems (Windows 7/8, Linux, etc.). It's called a Pico-ITX form factor and uses the same VIA Eden processor as the Dell Wyse thin client device.

And if you wanted to see a custom 4 node cluster of PICO-Itx mainboards, take a look at http://slipperyskip.com/page18.html

Something else to think about is that if you get 27 low power processors, you will need 27 power connections and 27 network connections to the internet. And 27 operating systems to keep up to date.

I'm going with twilyth on this one. I would rather have a full size motherboard with 8-12 threads and the ability to add some GPGPU's to the mix.

Hope that helps.
