| $ module load rocm/<version>
$ hipify-perl foo.cu > new_foo.cpp |

...
You can then compile the HIP ready . cpp file for the ROCm environment using the HIP/ Clang compiler provided in the ROCm installation:

There are several other utility scripts and options available to support the porting of codes that you can find in the rocm installation. These include:
| Code Block |
|---|
$ echo $(hipconfig --path)
$ findcode.sh hipcc hipconfig hipconvertinplace.sh hip_embed_pch.sh hipexamine.sh hipify-perl roc-obj-extract finduncodep.sh hipcc_cmake_linker_helper hipconvertinplace-perl.sh hipdemangleatp hipexamine-perl.sh hipify-cmakefile hipvars.pm roc-obj-ls |
for example:
| Code Block |
|---|
$ hipify perl inplace <filename>
It modifies the filename input inplace , replacing input with hipified output, save backup in . prehip file. |
| Code Block |
|---|
$ hipexamine-perl.sh <filename/directory>
This script will scan a file/directory to determine which file/files contain CUDA code and how much of that code can be automatically hipified.
|
| Code Block |
|---|
$ hipconvertinplace-perl.sh <directory>
It converts all the related files that are located inside the directory |

hipify-clanghipify-perlhipexamine.shhipexamine-perl.shhipconvertinplace.shhipconvertinplace-perl.sh
For example, hipify-perl -inplace option saves the HIP version of the code in the same file. The original CUDA code is saved in the backup file .prehip:

Or hipexamine-perl.sh scans a file/directory to determine which file/files contain CUDA code and how much of that code can be automatically hipified.
| Code Block |

$ hipexamine-perl.sh <filename/directory>

Or hipconvertinplace-perl.sh converts all the related files that are located inside the directory
