Render farm idea


Recommended Posts

I've been going through some configurations for a render farm lately and was wondering if this is a good way to get more power for the $$$

 

I don't have a bunch of old computer to utilize their CPU for a render farm, so I have to get everything new and since two cpu are better than one dual core with the same speed, I want to get more seperate stations as components in the farm.

 

So I was thinking to find a combination of simple MoBo and a pretty fast cpu(one generation old) with 1gb of ram. Put that in a cheap box that will have sufficient cooling, all for about $500-$600(maybe a bit more). At this price I can get few boxes and add more as I go.

 

Good idea? (stop laughing!)

 

Any idea about a hardware combination?

 

Thanks,

 

Dani

Erm, no:

 

First, two CPUs are not faster than one dual-core, unless you're talking about Netburst chips (P4 and equivalent). Also, more cores in one PC is better than multiple PCs with the same total speed. And costs less, because in addition to the CPU you need to pay for the rest of the PC. One $1000 box, put together correctly, will usually (in the current market) be better than 2 $500 boxes, but you'll need to do the math for your case.

 

Second, Core2 chips, which are only available in dual and quad core, have the best bang per buck available now. And they overclock like nothing else. There is no reason to buy P4, Pentium D, pre-5100 Xeons, most of what AMD sells, etc.

Dani,

 

What software are you using? I have a mixture of all those systems in my setup now, been putting together for a while now. I'm using Max with FR.

Just got done rendering out a 2500 frame animation using my systems and some systems at the firm I'm doing the animation for, and they all worked thru BB at the same time fine. Ram is the biggest thing, but it also is dependent on what you are rendering. and how you want to render. for animations I render thru Backburner. for stills I render using Finalrender DR. For DR I use only the fastest systems. but when sending to BB, I'll use any system I can get my hand on, the more Ghz you can throw at the multiframe job, the faster it will get done. Yes having all the systems quad or dual core systems would be the best. but lets say you had 2 duo core systems and it takes 20 minutes a frame. but you also have 10 older systems that take 60 minutes a frame. for the 100 frames, it would be faster for the 10 systems (10 frames an hour) compared to the 2 duo cores (6 frames an hour). I can get you more info on some tests if needed. for comparison.

Would it be better to get a server with two Xeon X5355 processors than two QX6700 systems?

 

That's not what I meant at all. Two single core CPUs are not faster than one dual core, all other things being equal. A Xeon 5355 pretty much is a QX6700, except you can use two of them, so that would of course be faster.

Also consider the cost of either a bunch of keyboard/monitors or setting up a K/M switch, the cost of power to run all those machines, the noise that your cooling will make, that each box need a full OS licence...and the space--real estate isn't free, either.

 

The idea is fine, overall. I've thought the same thing. But you can probably do better with a well-planned farm of multi-core units vs. many more single-core boxes.

With that said, I can see that dual quad systems is the best way to go considering the overall investment per system. I can start with two of them (16 cores) and get more as I go.

 

I'm using Max 9/MR/VRay/Premiere and want to create a powerful workstation with a multi core render farm that will take advantage of VRay's unlimited threads(10000 I think). The idea was to get more power for the buck and it looks like dual quads will get there faster, more quiet and smaller in size(cases).

 

If I understand it correctly, only MR needs extra license per 8 cores (right?) and all the rest is just OS license and setup. VNC is the main idea for updating and controlling each of the components.

 

Can anyone detail the hardware that a farm pc should have beside the MoBo, CPU, HD and RAM?

 

And also, what would be a sufficient ram per system without overkilling?

 

Thanks guys, it is greatly appreciated.

I dont know much about renderfarms, but I've been on a mission to read up about hardware to build such a farm.

 

A friend of mine at the Autodesk school is also a computer salesman, and he pointed the following gear out and he seems very confident that this is what you'll need to build a kick*ss farm.

 

It is easy to maintain, and super easy to add on, you can start the farm with 1 or 2 blades, and then add on as you have the money to spend. The chassis can take up to 14 blades, that means 28 Xeon processors :D

 

I'm not too much of a fundi when it comes to hardware, so I would like to get feedback on this setup. Would it work?

 

Server Blade

This server blade accommodates two Intel® Xeon® processors on an 800 MHz system bus and features up to 8 GB of addressable memory, flexible I/O, and storage expandability.

 

and

 

Server Chassis

The Intel® Blade Server Chassis SBCE integrates complex components and eliminates cables to simplify data center management. It even has communal DVD rom, USB ports, mouse, keyboard and screen output which can be assigned to any of the blades.

 

P.s.

I can supply links to more in-depth specs if anyone wants to read more

 

Cheers

I think already for some years about building a renderfarm, but everytime I calculate the cost of computing power, it comes down to that the newest processors are the cheapest. This especially if one considers all the other stuff that is needed ( mobos, ram, etc). Now I only buy what is really needed to do the job, because , first, stuff is always getting cheaper, and second, due to changes in pc architecture in my opinion one should not plan longer than max a year. In my calculations the cheapest machines (power per buck) are the core2duo quads. But if you have some older systems you can go with the core2duo 6400 and a asrock board. I did this, and am quite happy with it.

Renderfarm: what beasts should be chosen

 

For building a renderfarm with more than ten computers in a cost effective matter, it would be sufficient to just buy the required hardware.

So just motherboard, cpu, ram and cheap harddisk. Even the case could be replaced and just these hardware components set in a box, screwed on boards. There would come ventilators in and placed in an air-conditioned room. As Daniohayon mentioned, stop laughing ...

 

What choice should be made in MB? Athlon has had it best days, Intel has made a long jump again. Keeping in mind cost should be as low as possible, what is a good quality choice? MSI offers a good balance between cost and quality, are there others?

 

For CPU, athlon, intel ... what choice can be made and what type offers best quality-speed in combo with MB. Opteron seems one that is suitable for rendering.

 

Is 1024 Mb ram sufficient for rendering? As for 3D studio Max, to run the program itself it is better to have 4 Gb, but maybe for a renderfarm this is money thrown away.

 

Does the speed of the HD (for instance Raptor 10000 rpm) helps speeding up?

 

Is onboard graphic sufficient, as the software doesn´t have to work, only cpu.

 

Sterealkey, I would like to see those specs of those server blades, which brand are they?

 

I appreciate any suggestions.

sterealkey: does each blade need a windows licence?
