Actually, we went in a different direction, though I wouldn't say completely. We don't modify any existing code or anything like that. We include some custom software tools, though. The Render Garden uses some proprietary hardware to function. We ruined alot of good CPU's :-{ to bring it online. It's functional though, we use it ourselves. and it WORKS! It literally just plugs into your network and gives you slaves. You do, of course, have to modify your SET files if you're doing that. If you are buying a RG as your first 3DS hardware platform, then we do all that for you. They are chainable. You can hook up ALOT of them. Please feel free to ask me anything, though I might be able to answer them here.

Chris, could you please explain how RAM in the Render Garden is distributed to all the CPU's, and how this effects issues like file size, swapping, and render times? Thanks, -Alan Iglesias

Alan, Thanks for your interest in our "Render Garden/Farm/Jungle" rendering platform. I would be happy to discuss product information with you if you would contact me at the following number. For those of you following this thread – Read Steven Elliott's msg! At the conference we took an animation file from Matrox's Demo software and submitted it to our basic "Render Garden" machine. What took over 4 hours to render on Matrox's 486DX2/66 w/ 12MB computer (before he pulled the plug!) took just 39 minutes on our machine.

Hello Matt, Thanks for your reply. I'd be more than happy to call you and talk about your products at my first possible opportunity. Your product really sounds quite exciting, and could be a major boon to many animators, I'd guess. However, I'm really quite busy right now, and don't have an immediate need for your products. When I do (or a client does), I'll be calling and requesting all pertinent details. So in the mean-time, could you please tell us, here on the forum, basically how your multiple processors access the RAM, and how it impacts issues like swapping, file size, and render times? In other words, can a single 3DS file which uses, say, 98% of the machine's available RAM (in 3DS) to render still take full advantage of multiple processing power? If this is proprietary information, I totally understand, and I'll be happy to wait until such time as the information can be disclosed to me. Thanks very much, -Alan

Alan, More directly, we do have some proprietary issues at stake. However, our "RenderGarden/Farm/Jungle" operates transparently to 3D Studio – It actually "looks" like a normal network setup to 3D Studio. Our "Greenhouse" process monitor software takes care of the traffic control. To your question about a single 3DS file taking 98% of available RAM – 3D Studio network rendering distributes rendering data one frame/field at a time. Each assigned processor gets a frame – just like a normal network setup. After submitting the rendering job, the animator's machine is available to all 3D Studio functionality. After making changes, it is possible to submit the same job stream as a second concurrent job stream. Processors may be assigned exclusively to job streams through the use of "Greenhouse." The same limits that apply to current network rendering still apply to the swapping and file size issues. With the exception of render time – on this issue we have "optimized" 3D Studio network rendering functionality. Roughly, our entry level "RenderGarden" has accomplished a >4 hour project in 39 minutes with only 4 of the 5 avilable processors on-line. Also, proprietary components have been developed and manufactured to take advantage of critical performance areas. This machine is smart enough to sense a power failure and call or page the animator for his response. Basically, AM Labs personnel have both the hardware and software knowledge to integrate a very powerful "parallel" processing machine with the best animation software on the market.

Matt: Your product sounds interesting but I need some basic comparison info. Why would I be better off buying a (5) 486 box such as yours for $20K rather than buy 5 P90's with monitors, keyboards, CD-ROM drives, 1G HD's, etc. for the same $20k? or (5) P90's without monitors, keyboards, etc. for $15K? or (5) 486-66's for . . .

OK, Matt. Thanks for the info. So let me get this straight: >>Each assigned processor gets a frame – just like a normal network setup<< So, each processor needs enough RAM to hold one rendering job to keep from swapping, right? Which means that if I want, say, 4 processors to work simultaneously on the same network job without swapping, the machine needs at least 4 times the available RAM as the file requires to render one frame, right? Which means the primary difference between your system and a series of regular 486/66's is basically one case, video card, and power supply, etc., instead of, say, four or five, and the custom software, right? Sorry to be so curious, here, but your (or someone's) initial comments about this system included the phrase "parallel processing", which I understand to be defined as multiple processors sharing RAM, and working on one frame at a time, but REAL fast. This, I'm told, requires (at least) a renderer compiled specifically to sense a multiple processor arrangement. Also, If I'm gonna be reccomending a system like this to a client, I REALLY need to know exactly what's going on regarding these basic issues, so I can properly put their options in perspective. If I am off-base here, please forgive me, but I'm going on information from very reliable sources. If I am wrong, please straighten me out and I can learn a bit more about what my future may hold. -Alan

I'm afraid I agree with Bob, why does it make more $ense to buy the one box vs 5 (or 6 as prices drop) separate CPUs for the same money? Actually seems a tad risky to have it all in one. Momma always tole me that life is like a basket of eggs, drop it and the yokes on you… 😉 J-me

Let me just assure you that it works. I'm sure you understand. Depending on which unit you buy, the RAM is distributed differently.
