Anyone have any recent experience with building an extreme CUDA system using 4x 295s or similar? What are everyone’s general thoughts on the most robust system for these goals as of November 2009?
I read a previous thread which described building a custom case around the ASUS “P6T7 WS SuperComputer” motherboard.
I am however leaning towards a more pre-fab solution, such as those offered by SuperMicro such as the “SuperServer 7046GT-TRF”
SuperMicro also offers a newer motherboard that offers 7(!) PCI 2.0 x8 slots:
It is unclear though, if a double-wide card still obscures the adjacent slot. From the pict, it seems the slots are spaced a littler wider apart than normal, but I am not sure if it is possible to get 7 double-wide cards in this mobo, or “only” 4. Anyone know? Of course powering 7 cards without burning your office down is probably another challenge in and of itself…
Also this mobo uses x8 slots, instead of x16. Does it really matter much for CUDA?
And finally, anyone have a crystal ball that can inform me how these systems/mobos will do with Fermi?
I suppose the bottom line question is: what is currently the best hardware platform to host the max number of cards possible, and should we expect this to change at all with the release of Fermi? Do these choices from SuperMicro effectively represent the bleeding edge of what is possible at the moment, and will they remain good choices for Fermi systems?
Thanks for any insights into these matters…
