I have to solve the set of non-linear equations in 200x200x200x1000 variables space. I developed the parallel code in Matlab for that but it takes very very long calculation time. The solution could be GPU based algorithms. However, it is not cheap to get the license for commercialized GPU code.
Do you have any idea of homemade code for GPU based algorithm to solve set of 7 linear equations with 4D variables space in Matlab with MPI?
Thank you
For Matlab there is a GPUMat toolbox that is free and works fine.
You can found it in link below.
The other solution is triyng use trial version of matlab Parallel Toolbox (30 days) to verify if can solve your problems. Parallel for Matlab can accept also CUDA source code, I directly test that acceleration can reach up to 100x.

Dear Mr. Marco Jacono,
Thank you for your answer and link,
Actually I am looking for source code of solving non-linear equation in GPU. I tested a simple fft function in GPU using matlab toolbox, and it worked well. However, for GPU array of variables the fsolve function seems not work, so I am looking for another algorithms source code. Now I am try your link, I hope the GPUMat can solve it.
In order to solve large non linear systems in parallel with MPI, you can use PETSc, it is very efficient
