This is a follow-up question from linking the libraries for CUDALlink in Ubuntu 12.10.

The tests that I execute (CUDAQ[], CUDAInformation[], CUDADriver[]) seem to give successful outputs. However, when I try to execute actual CUDA commands the results are clearly wrong.

For instance, CUDATranspose[Table[i, {i, 2}, {j, 2}]] returns

 {{140191557896416,140191327433448},{17523916273012,0}} 

And the numbers change each time I execute it. I also noticed that some commands complain that CUDALink is actually not initialised, like CUDADot[Table[i, {i, 2}, {j, 2}], Table[i, {i, 2}, {j, 2}]]:

 CUDADot::notinit: CUDALink is not initialized 

But according to CUDAQ[], CUDAInformation[] and CUDADriver[] it should be. Before trying to solve the problem, how can I determine where it is? Is it within Mathematica? At the NVIDIA drivers level? Does it have to do with the gcc version?
