 `__host__` can combine with `__device__`, in which case the function compiles for both the host and device. These functions cannot use the HIP grid coordinate functions (for example, "hipThreadIdx_x", will talk about it latter). A possible workaround is to pass the necessary coordinate info as an argument to the function.
 `__host__` cannot combine with `__global__`.

-Next keyword is `void`. HIP `__global__` functions must have a `void` return type, and the first parameter to a HIP `__global__` function must have the type `hipLaunchParm`, which is for execution configuration. Global functions require the caller to specify an "execution configuration" that includes the grid and block dimensions. The execution configuration can also include other information for the launch, such as the amount of additional shared memory to allocate and the stream where the kernel should execute.

 HIP introduces a standard C++ calling convention to pass the execution configuration to the kernel (this convention replaces the `Cuda <<< >>>` syntax). In HIP,
-- Kernels launch with the `"hipLaunchKernel"` function
-- The first five parameters to hipLaunchKernel are the following:
+- Kernels launch with the `"hipLaunchKernelGGL"` function
+- The first five parameters to hipLaunchKernelGGL are the following:
    - **symbol kernelName**: the name of the kernel to launch.  To support template kernels which contains "," use the HIP_KERNEL_NAME macro. In current application it's "matrixTranspose".
    - **dim3 gridDim**: 3D-grid dimensions specifying the number of blocks to launch. In MatrixTranspose sample, it's "dim3(WIDTH/THREADS_PER_BLOCK_X, HEIGHT/THREADS_PER_BLOCK_Y)". 
    - **dim3 blockDim**: 3D-block dimensions specifying the number of threads in each block.In MatrixTranspose sample, it's "dim3(THREADS_PER_BLOCK_X, THREADS_PER_BLOCK_Y)".
