2D array on GPU

Compute with two dimensionnal array

Before begin you need to know how to create, allocate and use a two dimensionnal array in C#.

Hybridizer allow you to use multidimensionnal arrays instead of only one dimensionnal array, to use it we need to:

• use the -hybridarray option in the command line

• you can use the y component of threadIdx blockIdx blockDim gridDim to make a second loop to compute the 2D array.

• you can choose the size of the block and the grid with SetDistrib function

  dynamic wrapper = HybRunner.Cuda().SetDistrib(number_of_block_x,
                                                number_of_thread_x,
                                                number_of_block_y,
                                                number_of_thread_y,
                                                number_of_block_z, //the value is 1 in this example
                                                size_of_shared_memory //except if you use shared memory set 0
                                                ).Wrap(new Program());
  

Edit the file 01-Array2D.cs and use a 2D array instead of an 1D array.
