GPU and the MATLAB compiler

I am aware that GPU computing is not supported in the MATLAB compiler. I was wondering if this is just "temporary" and will be supported in a future version. If not, is there a work-around anyone can suggest?

Always in motion the future is. Difficult to see.

one vote for this!

If you are willing to write CUDA C code, you could just mex the code and include it with the MATLAB compiler.

What is the latest on this? Does the Matlab Compiler still not produce GPU code?

[Walter Roberson]

MATLAB Compiler still does not produce GPU code.

MATLAB Compiler is able to process code that uses Parallel Computing Toolbox, including the gpuArray() function, so it is able to use GPU.

Note that MATLAB Coder is not able to process GPU related functions. There is a GPU Coder product.

I think I get it. I understood the following:

• The Matlab Compiler does not produce new GPU code that does not already exist in Matlab.
• When the Matlab Compiler compiles Matlab code that calls the Parallel Computing Toolbox's internal code that uses GPUs (such as code that calls gpuArray()), then the compiled executable does call an available NVIDIA GPU and will fail if one isn't there.

And then I see the separate product that is designed to generate custom GPU code from various MathWorks products.

Thanks

That's about right.
