 This will only work with ROCM 1.7 and later.

 Compiling and running:
 ======================
-To compile you must set several environment variables in the Makefile in the src/ directory. For example, in order to compile using HIP without MPI, and up to 15 sub-iterations for a particle per kernel launch,  you could set the environment variables as follows (this is how they are set by default, you just need to point to where HIP is installed):
