HOW CAN I INSTALL A gt730 and Tesla K40 on the same computer in Ubuntu 1404

I have two GPUs, a GT730 for display and a Tesla for computation. However, it seems that there is no driver for ubuntu that can support both of these two cards, and the system doesn’t allow two different Nvidia drivers installed. My system is ubuntu 1404.

If there is any solution for this problem?

Since you want the tesla for computation, the driver that comes with CUDA 7 RC will work with your GT 730 and with the Tesla K40. Just install CUDA 7 RC. I using the runfile installer method.
