Hello! I have got a workstation DELL Precision T7920 recently. But the two GPUs installed are Geforce TX730 and Tesla P40 accelerator. The sales said that I could use the first one as the graphics card and use the second one to do the computing parts. I got very confused on that since I installed the Tesla driver 384.145 on Ubuntu 16.04, while I type ‘nvidia-smi’, there is only Geforce TX730 shown but I cannot see the Tesla P40. Is there any way I could use Tesla on a workstation?
Thanks so much for your time reading this! I’m really appreciated if you could help!
Hi, I have a T7820 and I never could manage to make the teslas work, despite I properly liquid cooled them. Looks that there is a restriction on the dell bios for those cards.
Specific SBIOS restrictions are unlikely. It is more likely that the system BIOS does not provide (by default at least) capabilities required by professional GPUs of the Tesla brand. In some cases you may be able to get things to work by dialing in relevant SBIOS configuration settings (e.g. size of BAR0 aperture). But looking at my own Dell workstations, such configuration settings are not even offered.
In any event running passively-cooled GPUs in workstation enclosures requires some creativity with respect to the cooling solution, otherwise the GPU will overheat and shut itself down for self-protection.
The designated professional GPUs for workstations are the Quadro branded ones. Dell typically provides a list which Quadro models are supported in which of their workstation models.
