title	Work in Progress for Phase-2 Documentation

The content of this section is currently being updated to include material relevant for Phase-2 of Setonix and the use of GPUs.
On the other hand, all the existing material related to Phase-1 and the use of CPU compute nodes can be considered safe, valid and up-to-date.

HIP: Heterogeneous Interface for Portability is developed by AMD to program on AMD GPUs.

...

The hipify perl script acts directly on the CUDA source code using a series of simple string replacements. Ex., (sed e ’s/cuda/hip/g’)

To convert the a CUDA file (foo.cu , for example) to HIP format, enter the following after loading hip/4.3.0

...

a ROCm module:

Column

width	900px

Code Block

language	bash
theme	DJango
title	Terminal N. Loading ROCm module and using the hipify-perl tool for translating the code from CUDA to HIP

$ module load rocm/

version

<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:

Code Block

language	bash
theme	DJango
title	Terminal N. Compiling the code

$ module load rocm/version

with hipcc

$ hipcc new_foo.cpp

there There are couple of utility script availed several other utility scripts and options available to support the porting the codes

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

for more information see HIP/hip_programming_guide.md at develop · ROCm-Developer-Tools/HIP · GitHub, HIP/hip_porting_guide.md at develop · ROCm-Developer-Tools/HIP · GitHub, HIPIFY/README.md at master · ROCm-Developer-Tools/HIPIFY · GitHubof codes that you can find in the rocm installation. These include:

hipify-clang
hipify-perl
hipexamine.sh
hipexamine-perl.sh
hipconvertinplace.sh
hipconvertinplace-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:

Column

Code Block

language	bash
theme	DJango
title	Terminal N. Compiling the code with hipcc

$ hipify-perl -inplace <filename>

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

Code Block
$ hipconvertinplace-perl.sh <directory>
