I’m sure we have all been in the situation of hardware/software incompatibility where the products in question are made by 3 or 4 different manufacturers. They quickly form a circular firing squad and resolution is protracted.
I would like to put together a system and don’t really want to order $3000+ min hardware and find out it doesn’t work together. Happily almost everything is made by one company: nVidia!
Will the following work together:
Three nVidia 9800GX2 GPU cards,
One nVidia 780i or 790i motherboard with Nvidia chipset, nVidia approved memory, quad CPU, latest nVidia BIOS and drivers,
One 1200 watt Nvidia approved power supply, adequate cooling system
and, of course, Nvidia CUDA 1.0 or 2.0 ?
What is the minimum PCIe requirement for nVidia 8000, 9000 and Tesla series cards for nongraphic use with CUDA. I know they must be x16 physical connectors. What about electrical channels? 16 and 8 work, what about 4 or 1? PCIe is supposed to auto negotiate the channels. Will your boards do the same?
I know the host/device bandwidth will go south but in some applications it is a negligible consideration.
I have posted this here rather than a email to nVidia as the answers may be of interest to other users of this forum.
PS I have already searched the nVidia website with no success.
