how about using tesla's with cycles?<br><br>http://jeffpatton.net/2010/11/gtxquadrotesla-my-opinion-on-todays-gpu-selections-for-rendering/<br><br>performance seems to be almost the same compared with high end gaming cards but will cycles work with these teslas? <br><br><br><br>------------------------------------------------------------------<br><br><div>> From: lalli@gmx.net<br>> Date: Wed, 16 Nov 2011 14:20:21 +0100<br>> To: bf-cycles@blender.org<br>> Subject: [Bf-cycles] cycles, some questions about GPU<br>> <br>> Hi Brecht and Followers,<br>> <br>> i'm currently building a new (triple Boot, osx, linux, win) computer, mainly for use with blender/cycles.<br>> <br>> So there's the Thing i'm struggling a bit: The GPU.<br>> <br>> Since those question will probably come up for other blender users as well i would like to ask you once and put a summary on my website (bwide.wordpress.com) for everyone.<br>> I did a good amount of searching the web for answers, but haven't found.<br>> <br>> So the Questions are:<br>> <br>> Cycles GPU Rendering currently is limited by the amount of available memory on the GPU, as far as i know. <br>> 1.-will cycles be able to render scenes bigger than the available Memory on (one) GPU?<br>> 1b.-if, in future, cycles uses multiple GPUs will it be still limited by the max amount of memory on one GPU or by the sum of all?<br>> <br>> 2.-Is the rendering speed mainly determined by GFLOPS?<br>> 2b.-if not, can you tell me what is?<br>> <br>> 3.-Does Cycles make use of any "newer" NVIDIA technology? I mean will an older GPU (cycles ready) with same specs as a theoretical new One render at about the same speed?<br>> <br>> 4.-Cycles doesn't care about Nvidia SLI, "just" (will) use all GPUs, right?<br>> <br>> 5.-Will cycles care about different GPUs (for example 1xOlder Cuda, 2xNew Cuda)<br>> <br>> 6.-Will/might it be possible to mix Cuda and OpenCL GPUs?<br>> <br>> 7.-Is there a chance that, in future, currently older GPUs like gtx 295 will drop out of Cycles support? <br>> <br>> 8-. just for private use: Do you recommend any GPU?<br>> <br>> Just wondering:<br>> 9.-I know you can't tell, but when you think will multiple GPUs be supported (CUDA)?<br>> <br>> 10.-Do you know/predict anything about significant speed differences (of cycles) between CUDA and OpenCL?<br>> <br>> 11.- Between 0-100%, approximate about where is cycles development at the moment.<br>> <br>> <br>> That's it for the moment.<br>> <br>> <br>> And i'd like to thank you for your amazing work on cycles and blender in general. <br>> <br>> Have a nice Day.<br>> <br>> bashi<br>> _______________________________________________<br>> Bf-cycles mailing list<br>> Bf-cycles@blender.org<br>> http://lists.blender.org/mailman/listinfo/bf-cycles<br></div> </div></body>
