I am running a Core i7 system dual boot between Windows XP 32 bit and Windows 7 64 bit and am having trouble with configuring my Tesla C2050 along with a GeForce GTX560 Ti(or ANY nVidia card). I am also running 3 displays with this configuration (so ALL video outputs have to work).
My problem is that once everything is in and running, CUDA enabled software (almost ANY software save benchmarking and monitoring) will not run on the Tesla but will instead run on the GeForce card only. If I pull the Geforce card out and replace it with an ATI Radeon, the Tesla runs just fine. Is there any way (maybe a registry tweak?) to force the CUDA software to run on the Tesla by default (or ideally on both the Tesla AND the GeForce cards simultaneously?)
The Tesla installation manual says that nVidia graphics drivers must be uninstalled before installing the Tesla, which I did. Install Tesla driver, then graphics driver. Tesla won’t run. Then I read a tech note saying that the Tesla drivers must be installed after/over the graphics drivers. Did that. All the displays work fine. Tesla won’t run. Pulled OUT the GeForce card, installed an old ATI Radeon X1950 card, Tesla runs fine. This is happening regardless of which OS I am running.
I can’t find anything on the net about this problem (I can’t be the only one?)
