Got a HBS (y'know, Honkin' Big Server, one o' them technical terms), a Dell 720 with two Tesla GPUs. I updated the o/s, 6.5, and I cannot get the GPUs recognized. As a last resort, I d/l NVidia's proprietary driver/installer, 325, and it builds fine... I've yum removed the kmod-nvidia I had on the system, nouveau is blacklisted, and when I reboot, lsmod shows me nvidia loaded, which modinfo tells me looks like the one I built.... but enum_gpu, which is from a CUDA group, builds... but can't enumerate the GPUs (how we wake them up for the users). I see the /dev/nvidia*, and they're a+r, a+w.... Oh, and selinux is permissive. Anyone got a clue? If I can't get this working, I'm going to have to downgrade the system several kernels. mark
