I would like to use image clustering with GPU. Please provide me an example on it. OpenCl is a platform but its a platform not a tool. Please clearify if any other method is availbe directly to utilize GPU.

To use the GPU with MATLAB, only CUDA is supported and you need the Parallel Computing toolbox.

You must also have a GPU with compute capability 1.3 or higher ( http://developer.nvidia.com/cuda/cuda-gpus). It looks like your card has a compute capability of 2.1 so you should be OK.

I would offer a word of caution regarding the performance of the GPU -- according to the specs for the GPU ( http://www.geforce.com/hardware/notebook-gpus/geforce-gt-520mx/specifications), it has only 48 CUDA cores, and the amount of memory is not specified. The performance of this card isn't likely to give much of a performance boost -- as a comparison the GTX 680 has 1536 cores and 2 GB RAM on the card, and the Tesla C2075 has 448 cores / 6 GB RAM.

For examples, there are a number here: http://www.mathworks.com/help/distcomp/examples/index.html#gpu

THANX JILL, I WILL TRY TO EVALUATE IT AS SOON AS I REACH TO LAB..KINDLY SEND ME ANY LINK FOR EXAMPLES REGARDING THIS.

To use MATLAB with the GPU, install the proper driver from nVidia's website -- make sure you get the CUDA enabled driver. MATLAB will find the device and you can start using it.

There have been a number of new GPU-related features added each release since 2010b, so I would recommend you look into getting the most recent release that you can. The link I provided has the relevant examples in it.
