Hi,
We have explored this a bit and the cuda -> hip translation process is fairly straightforward. The only sticking point is that LBPM uses some cuda 10 features to perform parallel reductions on the GPU, and I do not believe these are supported by HIP right now. Otherwise it is a fairly straight shot.
It is reasonable to anticipate that LBPM will be compatible with both AMD and NVIDIA GPU in the longer term. This is something that we are actively developing as a part of the Frontier CAAR program.

Thanks for the response @JamesEMcClure
Yeah there are two fucntions that are not defined by HIP yet
sycl_shift_down and
this_thread_group()
I have tried and ported and in 33 testcases 3 testcases were not running and i am getting segmentation fault
TestForceD3Q19
TestBubbleDFH
TestFluxBC
I beilieve they are failing because of GPU Aware MPI which is causing segmentation fault
Thanks
