LONG POST!! - Cruncher Farm mass WC project

As promised, I'm here to report on my farm's mass water cooling project....... Wow, where should I begin? How about we start from the beginning....:p:

In the beginning, God created the Heaven and the Earth.
And the earth was without form............Wait a minute, that's a bit too early in the beginning......:D :ROTF:

Let's try this.....I've been a "lurker" in the liquid forum for quite a while. I finally had something to ask and joined up in Mar 07. While hanging out there, a thread started titled AARP blah blah blah. It was, and still is a golden thread. I met Movieman there.

Then there was this "contest" between something called XSTA and XSTM. Dave PM'ed me to ask me to come and help out. I knew a tiny bit about distributed computing, but I could not figure out where to start. (Quite frankly, each of the teams needs a short, concise, explanation of who they are, what they do, and why a rookie should join up. This should be a sticky, and locked to prevent it from getting hijacked.....Of course, I learned later that Dave is probably one of the best thread-jackers on XS!! :eek: )

I joined up and put a QX6700 machine on the team. I followed all the banter and participated in a bit myself. I also saw the blow up occur and stayed out of it since I didn't know what was going on. My mantra was crunch, crunch, crunch. In the process, I saw a lot of you show your character. I was very impressed with the caliber of folks on this part of the forum. I made a commitment to the cause, and to the team, that a farm was coming.

I have thrown thousands of dollars in the toilet, in the past, on wasted hobbies and too many interests. (not counting my bar tabs...:toast: :rolleyes: ) Well, you get older and smarter. It's really true.... I finally found something here that I could get my hands on. For me, it's about cancer. That's why I crunch and spend money. I've given to American Cancer Society in the past, only to wonder what that money did to help. This way, I can see it by the project reports. I'm not about points. I'm about the cure. When I pass, I do so quietly. When I get passed, I pull over to the side to let the teammate by. (Now Team 2ch, that's another story, we can't let them get too far ahead of us!!:yepp: )

So, I'm a professional staff electrical engineer for Motorola Inc, designing public safety communication systems. Now what? I build a rack of machines of course!!!:D :D

Here it is, as well as me, after cleaning out the hamster cages....

http://i149.photobucket.com/albums/s...farmerbob2.jpg

Anyone familiar with sharp farm implements will notice that I'm holding a manure fork, not a straw/hay pitchfork. Anyone doubting this can look here I have the number 74223 fork....Didn't know they still made it....Good to know that cr*p hasn't changed much over the years....Those hamsters are quite the producers of manure, particularly with the special DDT chow....

I knew I wanted to water cool this rack so I threw on all the best coolers I had, and refused to buy more air coolers. I was left running the lower machines on stock coolers. This led to loaded temps in the 70s....:mad:

Working with Alex at Petra's, I came to the following plan.

http://i149.photobucket.com/albums/s...gram-plans.jpg

Alex suggested the series pump idea for redundancy. I decided to make two loops. I came to this plan with HW failures in mind. If one pump fails, no biggie. The other pump is there. If two pumps in a loop fail, it's worse, but water will (and does) flow backward through the failed loop from the other loop. Quite remarkable. (And yes, I know you're not supposed to run water through a Laing backwards, but remember, it a failed loop, so who cares?)

Here's the initial parts pic of the main gizmos in the plan. Got to have that on a build thread. Notice the pink/orange Petra pen? I've got a few of those. The whole mess was about $1,100 with additional tubing and parts I added later. And for Dave the XS toolman, that is a digital machinist's caliper on the mat....:D As near as I can figure out, the radiator is from an 88 Chevy Astro Van. It was at a friend's body shop with no vehicle around it. The price was right, so I didn't mind cleaning it out....THANKS JIM H!!!

http://i149.photobucket.com/albums/s...partsbegin.jpg

(Shameless plug. Petra's absolutely rocks for watercoolers. Best place for a noob too. Alex or Quoc will always steer you right, and away from the junk kits out there....)

OK, here's lots of stuff put together. Cable mess, WC rack proto, I know, a bit ugly. Clean up will occur on placement to final location. The WC gear is going to go on a rack mount tray. That's why it's prototyped the way it is. Nice and compact. The 2x2s will go away...

http://i149.photobucket.com/albums/s...ackandquiz.jpg

OK, quiz time. This took me a bit to figure out. Look in the middle of the cooler at the white 3/4 cap sticking up. You'll see I have plumbed a T-line. I had thought that I would have to use it to charge the upper machines in the rack. I don't. I can fill by using only the radiator cap. Most convenient...:D :D Why doesn't the water from the higher machines just spill out and overflow the rad cap? Notice the cap is off in this pic and the upper machine tubes are full. Ten points to the first correct answer and 20 to the most complete. This should spark the hydraulic folks out there....I think I know the answer, but I had to consult an old fluid dynamics book. This was a pleasant accidental design element for me. It's cool to be able to treat maintenance on this like a car...

More details on how to handle mass cooling hose placement in a machine for service. This is the outside of the top machine in the rack. Note the grommets.

http://i149.photobucket.com/albums/s...1reartubes.jpg

....and the inside of the same machine. This allows you to pull the entire machine by dis-mounting the CPU block and pulling it up through the slots. That way, you don't have to stop all the machines and drain the loops to pull a single machine out. In addition, the hoses are long enough to allow the machine to come forward full for servicing without doing anything. I'll be reporting on how this goes in future posts. I've got to come up with a service jig to make this easy.....

http://i149.photobucket.com/albums/s...ubesinside.jpg

Now detail on the WC main part. The pics are front (with 120mm fan for scale), RH side, Rear, and LH side in quick order. I can make more detailed pics of any areas you may be interested in. No secrets here. Remember though, this is proto.....

http://i149.photobucket.com/albums/s...cs/WCfront.jpg
http://i149.photobucket.com/albums/s...s/wcrhside.jpg
http://i149.photobucket.com/albums/s...ics/wcrear.jpg
http://i149.photobucket.com/albums/s...LHsideview.jpg

On the LH pic notice the house well pump filter. This is something we are VERY familiar with here in the Pac NW. This is on the suction/supply side of the gizmo. It is for filtering out the odd crap that is STILL coming out of the rad. It is 50 mesh, or about 300 microns. I don't suggest any finer or coarser. 50 mesh is perfect. This was about 80 bucks, not cheap, but a lot cheaper than throwing chunks into your loop of $5k worth of quads....Also notice the ball valves on the filter. These are used for air bleed of the system. I'll post more "how-too" on that later. It took awhile to come up with this, and lots of distilled water sprayed around...:D

OK, you've either stuck with me for the above, or came to the bottom for results. Here they are.....These contain my initial coretemp numbers, an interim step when I had 3 machine in one loop, and two flavors of finals. Oh, I forgot, part of what I did was develop a custom speed controller for the fan. I have two speed levels of data here. On low, the WC machine is VERY quiet for it's size. On "medium" it's about like a 20" box fan on low setting. At high, well, it is a van radiator after all.....:eek:

http://i149.photobucket.com/albums/s...stresults3.jpg

What's next?? OVERCLOCK the living be-jeebers out of the farm!!! Look how low the clocks are now!!! That's not very Xtreme!!:mad:

I'm not a very accomplished clocker. Expect a bunch of questions on this topic. I looked at some posts and go WTF, how can you get that thing that high....I'm missing something here...

I sincerely hope this gives some inspiration to all those struggling with temps and farming. Car radiators rock, for the right application. This can be made cheaper if you wish. I am always open to PM for most questions if you don't want to post. I would encourage you to do so though. That way, we all learn, as I have....

Thanks much to all of you, my teammates, cheers...:toast:

Bob, I must say I am quite impressed with your hard work and dedication.. There are many here among us that go pretty far to get crunchers running efficiently.. Well, you've gone above and beyond and for this I solute you:D

Now, get your spare bedroom ready I'm heading out there and we'll oc the hell out of those thing;)

Dave never goes off topic I have no idea where you could have even though of such a thing..:rofl::sofa:

That is one big cooling station you ave there:up:

I'm still impressed by the looks of racks it has something...

But for maintenence wasn't it easier to use quick release connectors on each case? Now you will have to open up the case before you have it out of the rack.

Well now go for the clocks every mhz will count:p:

It's two series loops. Can't do quick connects.....It would burn the other two machines in the loop. Thought about that too...

Incrediable job, well done!

crunching for a cure does make this hobby alot more fun, and I am 38, so now my family seems to understand a bit more, and the wife is beginning to give me a bit more leeway on the budget. So when the house is done, may have have to sow a few seeds, and get the hamsters multiplying myself.

Again, well done.

Bob... I'm still thrawling through the information. This has helped my day.

Any you're not too ugly either.... for an old guy.. :D

EDIT: Oh... that watercap open in the rad, is it because the feed and the return for the upper machines... the rad points are submerged, so no back air to replace the possible displacement? Damn... archimedes died a long time. :)

Ow yeah forgot about that. BTW are you going to build a cover for over the box?

Edit: One question tho, wasn't it easier if u used the 1u version of the block? Well maybe not because the hoses needed to go out on the top of the casings.

I'm going to build it onto a standard "centerweight" rack shelf. It's the same as the shelf with my monitor and keyboard in the pic. It will go on rack#2, which I picked up Saturday. I'm likely going to go with an expanded metal cage around the unit. I'll also make a slot to hold a 20" by 20" furnace filter in front of the rad.

The whole mess is going to move out to the garage as soon as I'm done running dedicated circuits. Good thing I put in the biggest service box I could find when I re-did the service panel in the house. I've got 13 empty breaker slots.

I think you're talking about the GPU version of the fuzion, right? I really didn't think about using those. I used these blocks for the purpose of routing tubes through the top back edge of the cases. That way they could be pulled out and separated from the case without disconnecting the loop. I'll have to look at the other blocks for rack#2. They might work better...

Thanks for the kind words..I think!:D
That AARP thread brought some excellent people into WCG including yourself.
It also allowed me to meet you,Sigfever,HardH20,IanY,and some others.
That was MY pleasure as I've always beleived it is the people here that are the great resource of XS and when we work together there is no goal that we can't accomplish.

Excellent job there my friend and well thought out.
You showed with this the one kind of thinking I see so much of on Xs:
Outside the box..
You took a situation and created your own way of making it work.
Very nicely done.:up:

Get some more hamsters and you will need a silage fork to feed them:D

Dammit, so many replies since this morning.
For those that aren't in the know, a silage fork is almost twice as wide with more tines and a sharper deflection. It has a deeper scoop and a shorter handle.

Good to see someone who knows their forks....:D

The number 76134 fork here would be just the ticket. When rack #2 is completed, I may have to build a silo to store the feed....:rofl:

Bob

You have to know these things so you don't get :banana::banana::banana::banana::banana:ed at for using the wrong fork and contaminating feed.
This fork with sh*it on it is on this rack for a reason, use it to bed stalls and gutters, use this wider one for throwing hay out to the older calves, use the broom to push up hay and silage, use this fork for feeding silage.
Now, I'm sure ddtung knows what kind of silo to use for feeding hamsters. If we're talking dry feed a bin might be a better idea. I'm not sure if these hamster steroids are a powder or some type of liquid. For damp hamster food a silo would be the way to go. For pellets a bin would be better. Of course how many bushels the hamsters can go through would need to be considered as well to decide which would be more economically viable.
Recap:
Pellets
super special hamster food with water and electrolytes

Duh

how about in a near future designate someone who offers to receive some extra cash from XS WCG members and make some pretty kick ass rig?

kick ass rig: 2x dual clover in a 1U case :toast:

total cost would be under 10 k ( no drives and no vga)

It's sexy but it's not dollar wise. really, a Q6600 on a rack is the smart way to run..either air or water cooled depending on your climate.
Clovers are sweet and I think that with the new 45nm xeons we might see 35K in a day from one box, the quads just can't be beat.
I'm waiting for someone to get a "good" Q6600 G0, water cool it and run it at 4200 24/7..At that speed it will be the best deal for a cruncher by far when points vs investment is added in. Maybe 21K a day from a quad like that.

@dave

but how about considering that for each righ you will be needing :
-an extra mobo ( considering you will be able just to run one cpu in one board;a good one actually that can OC considerably)
-liquid cooling gear expect to spend 200-300
-an psu

i was thinking this some days ago..
