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.
ROCm environment offers two automated methods for automatically converting CUDA projects to HIP: Hipify perl a Perl script you can run on the CUDA source code to convert it to HIP format and Hipify clang a preprocessor that operates from within the HIP/ Clang compiler tool chain, converting the code as a preliminary step within the compiler process.
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 CUDA file foo.cu to HIP format, enter the following after loading hip/4.3.0
$ 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:
$ module load rocm/version $ hipcc new_foo.cpp
