I have matlab 2014b running on my Ubuntu 14.04 LTS 64bit, Nvidia and CUDA (6.5) drivers are the newest. When I use gpuArray I get the following error: "Error using gpuArray The CUDA runtime failed to initialize correctly. This can occur with some older CUDA drivers."
I tried everything but nothing helped. Please help me with this matlab bug.

What does
parallel.internal.gpu.CUDADriverVersion
return? Also, could you try running
version -modules
and posting any lines that match libcuda.so.

The commands "parallel.internal.gpu.CUDADriverVersion" and "version -modules" is not possible to run on a system with MCR only. Linux server 64-bit without any x-server og display manager.

I had a similar issue after ubuntu updated to the nvidia-331 driver today. However the issue went away after I ran matlab with sudo once. I'm guessing it needed permission to modify a file after the driver update.

The problem solved by removing and reinstalling the CUDA driver. It is working now. No changes in driver and it is the same driver.
parallel.internal.gpu.CUDADriverVersion: ans = 340.29
Thanks!

make sure you have the paths set properly in your .bashrc file (or similar .cshrc file). export CUDA_HOME=/usr/local/cuda export LD_LIBRARY_PATH=${CUDA_HOME}/lib64 PATH=${CUDA_HOME}/bin:${PATH} export PATH
