How to estimate the accuracy of converting HIP to CUDA or converting CUDA to HIP?

How to estimate the accuracy of converting HIP to CUDA or converting CUDA to HIP? As we all know, HIP could support CUDA definitely.But how to estimate its support accuracy,which is important to using HIP.Is there some tool which could fix this problem?

This could be done by some test suites about fp operations. Unfortunately, I am not aware of one for CUDA/HIP.

There is a research paper about math function accuracy of various math libraries, including CUDA and HIP (ROCm)

@NiuKeke I'm not sure we're clear on what kind of accuracy you mean. Could you elaborate?

I mean if there were some test suites about CUDA/HIP just like opencl-cts, which could be a criterion of Opencl.

thank you!I mean if there were some test suites about CUDA/HIP just like opencl-cts, which could be a criterion of Opencl.
