I accidentally got a Lenovo ThinkCentre D30 in the early July. This desktop had only one GPU card (Quadro 2000), and this card was not that suitable for what I was doing, you know the fancy deep learning stuff. So I accidentally picked another card, Tesla K20c in early Dec. And Felt so excited and can’t wait to set it up.
I plugged in the new Tesla, and insert a Ubuntu 12.04 DVD to refresh the whole system, then I installed the CUDA 5.5 driver step by step, and step by step. Finally, I lspci and found that this freak system just could not recognize my new shiny Tesla ;-((
What I want to do is: keep the Quadro as the display card, and use Tesla to do some scientific computing, I would be so grateful if anybody, I said, ANYBODY, saved my ass.
