Not able to Compile a GPU MEX-File

Hi,

I was trying to compile the GPU mex-file as it is written in the Matlab home page

http://se.mathworks.com/help/distcomp/run-mex-functions-containing-cuda-code.html

But it says error with compute capability. I am not a sudo user. It seems I need to change the flags in the mex_CUDA_glnxa64.xml file. But I am not sure. Could any one please help me, thanks.

setenv('MW_NVCC_PATH','/usr/local/CUDA/bin')

>> mex -largeArrayDims mexGPUExample.cu

Building with 'nvcc'.

sh /tmp/mex_157937607297064_15337: Signal 127

Error using mex nvcc fatal : Unsupported gpu architecture 'compute_50'

Hi, you need to install the CUDA toolkit matching your version of MATLAB.

gpu = gpuDevice;
gpu.ToolkitVersion

At the moment you are trying to build your mex file using an older version of the toolkit than required by MATLAB.
