Matlab 2011b and Cuda

Hi,

I downloaded and installed Matlab 2011b and, among other, the parallel toolbox. I do have an Nvidia CUDA card on my computer and with version 2011a I was able to use the cuda in matlab very well. In 2011b, however, I receive the following error if I try to do anything CUDA related: "Error using gpuArray (line 28) The CUDA runtime failed to initialize correctly. This can occur with some older CUDA drivers. Make sure that you have the latest CUDA driver for your system from NVIDIA."

I have CUDA 4.0 installed on my computer. I am running Ubuntu 11.04 64bits. If I open the 2011a version of the Matlab everything works fine.

It appears that new drivers (Linux version #270.41.19) were released about a month ago; perhaps that would help. See http://developer.nvidia.com/cuda-toolkit-40 to download the drivers

I have the same problem now with Ubuntu 14.04 with the news CUDA driver and Matlab 2014B. "Error using gpuArray The CUDA runtime failed to initialize correctly. This can occur with some older CUDA drivers" Somebody has any solusion?

I can confirm that. Same problem on Ubuntu 14.04 with nvidia-331 driver on MATLAB 2014b.

Any recommendations???

As Walter says, there are some relatively new CUDA drivers available for Linux, it's definitely worth getting the latest. If you still have trouble, please could you post the result of running

parallel.internal.gpu.CUDADriverVersion

Raghavendra Ramachandra: You are replying to a question from 5 1/2 years ago. Please indicate clearly which MATLAB version you are trying to use, and which operating system, and whether you are using 32 bit or 64 bit MATLAB, and the variety of card you are using.

The closest match I find to the driver number you provide is 368.86-quadro-tesla-grid-winserv2008-2008r2-2012-64bit-international-whql.exe which appears to be for Tesla card for the 2012 timeframe running on Windows Server 2008.
