MPI Ghost Exchange Optimization Examples Changes Between Example Versions This code contains several implementations of the same ghost exchange algorithm at varying stages of optimization: Orig: Shows a CPU-only implementation that uses MPI, and serves as the starting point for further optimizations. It is recommended to start here! Ver1: Shows an OpenMP target offload implementation that uses the Managed memory model to port the code to GPUs using host allocated memory for MPI communication. Ver2: Shows the usage and advantages of using roctx ranges to get more easily readable profiling output from Omnitrace. Ver3: Under Construction, not expected to work at the moment Ver4: Explores heap-allocating communication buffers once on host.

Check with module show rocm or echo $HIP_PATH Also, the Makefile builds and runs the code. We’ll do the steps separately. Check also the HIPFLAGS in the Makefile. make vectoradd_hip.exe
