Hi ,
Im sorry if this has been asked already , couldnt find answers via search and ive read all "do you want a lot of outputs" documentations.
For a client we are looking at a lot of servers, each servers will have to handle one or two independent facades with 6-12 projectors blended per facade. No need for a framelocked system for most surfaces.
I got access to about 30x RTX3080 cards, a lot of recent pc components (nvme ssd's, ddr4 16gb ram sticks etc) and a budget for Datapaths and or other IT gear.
1- Would it be possible to use 3 or 4 gpu's on one motherboard ? 1 gpu doing the texture rendering and sending it to the other cards ?
2- To take off a part of the load i would have the content composition running on a seperate machine and sending the output via ndi / capture card to this "mapping server"
Any recommendations for 4k or even 8k capture cards ?
3- Could i run into general bandwith issues with 1 capture card processing a 4k30 input and 3 gpu's with a total 11 outputs ? I would think the motherboard can handle all this traffic if its designed for so many slots ? https://www.gigabyte.com/Motherboard/WR ... -rev-10#kf
4- How about if i add one or two datapaths to the main GPU and in total increase to 17 outputs ? Im putting a heavier load on everyhing but theoretically it should work ? Are the outputs from a datapath in sync with the other 3 outputs of the card its connected to ?
5- For one location im thinking to use 3x servers , each with 2x RTX3080 (instead of more datapaths as i got the cards already). Each of these servers would output to 4 projectors on one card and have a GUI output on the second card (could use remote access for the GUI and not use the output but rather not..).
I would then have one "composition server" that feeds each of these mapping servers via capture card, their portion of the output texture to map it to assigned surfaces.
Anyone experienced with such a "distributed system ?"
6- Just theoretically, if i would make 3x media servers , each with 2x quadro p4000 card, capture card and a quadro sync II card, can i use these servers as a framelocked distributed system , each capable of handling their part or a large, 20+ pj blended canvas ? Could i even add datapaths to these p4000's ?
Thanks alot in advance !
