What about merkle-hip on AMD GPU?

Thank you for reporting the issue. I will try to investigate the issue on an AMD GPU.

The results are compared when DEBGUG is ON in the Makefiles. The GPUs are MI100, V100, and A770. The output results of the SYCL program are the same on the Nvidia and Intel GPUs. The SYCL results on the Intel and Nvidia GPUs match the result of the CUDA program on the Nvidia GPU. The output result of the HIP program on the AMD GPU does not match the results on other GPUs and the SYCL result on the same GPU.
