  The open source HIP platform for GPU computing provides an uniform framework
to support both the NVIDIA and AMD GPUs, and also the possibility to porting
the CUDA code to the HIP- compatible one. We present the porting progress on
the Overlap fermion inverter (GWU-code) and also the general Lattice QCD
inverter package - QUDA. The manual of using QUDA on HIP and also the tips of
porting general CUDA code into the HIP framework are also provided.
