I have two 9800 GT’s (with SLI disabled), but cudaGetDeviceCount() only returns 1, so there’s no way I can select which GPU to use to run the code. I’d prefer to use the secondary GPU so that it doesn’t glitch my desktop when I’m running tests. It’s also interesting to note that when I go into the Physx control panel, I cannot select which GPU to use for GeForce Acceleration.
Any ideas what might be causing this?
I’m using the 178.24 drivers, under Windows Server 2008 x64.
That’s not correct. If I go into Display properties and, I can choose to extend my desktio onto a non-existent monitor, but no changes will be made after I click Apply. I am still left with one main monitor and three inactive monitors.
