Notes CUDA

Notes for CUDA

1. Setting grid and block dimensions
   • Un-initialized dimension (.x, .y, .z) is set to 1 by default.

      dim3 grid (1024, 8);
      dim3 block (512, 1);
      myKernel<<<grid, block>>>(d_data);
     

2. Don’t do this:

    dim3 grid = (1024, 8); // !!!! Wrongly initialised values!!!!
