We have tested the Nvidia Titan and Tesla K40. ### Do HIPIFY tools automatically convert all source code? -Typically, HIPIFY tools can automatically convert almost all run-time code, and the coordinate indexing device code ( threadIdx.x -> hipThreadIdx_x ). +Typically, HIPIFY tools can automatically convert almost all run-time code. Most device code needs no additional conversion since HIP and CUDA have similar names for math and built-in functions. The hipify-clang tool will automatically modify the kernel signature as needed (automating a step that used to be done manually). Additional porting may be required to deal with architecture feature queries or with CUDA capabilities that HIP doesn't support.
