capitalized id does not work when the HTML link is clicked.

-The hipLaunchKernelGGL macro always starts with the five parameters specified above, followed by the kernel arguments. HIPIFY tools optionally convert Cuda launch syntax to hipLaunchKernelGGL, including conversion of optional arguments in <<< >>> to the five required hipLaunchKernelGGL parameters. The dim3 constructor accepts zero to three arguments and will by default initialize unspecified dimensions to 1. See [dim3](#dim3). The kernel uses the coordinate built-ins (thread*, block*, grid*) to determine coordinate index and coordinate bounds of the work item that's currently executing. See [Coordinate Built-Ins](#Coordinate-Built-Ins).

 Please note, HIP does not support kernel launch with total work items defined in dimension with size gridDim x blockDim >= 2^32.
