Thanks for that info, I hope that is the case.

I've just had to restart both of my GPU-equipped machines and upon reboot
mfaktc fails to run on both machines:

mfaktc v0.19 (64bit built)
CUDA version info
  binary compiled for CUDA  4.20
  CUDA runtime version      0.0
  CUDA driver version       4350.57
ERROR: CUDA runtime version must match the CUDA toolkit version used during compile!
nvidia-smi -a tells me:

NVIDIA: could not open the device file /dev/nvidiactl (No such file or directory).
NVIDIA-SMI has failed because it couldn't communicate with NVIDIA driver. Make sure that latest NVIDIA driver is installed and running.
Attempting to reinstall the driver tells me I already have the latest
driver. lshw indicates that the GPU card is using the nvidia driver:

configuration: driver=nvidia latency=0
printenv | grep cuda shows the correct entries in LD_LIBRARY_PATH
and PATH.

So what am I missing? Why isn't my CUDA setup being maintained
across reboots/power cycles? Is this really normal behavior????
