HIP Python

This repository provides low-level Python and Cython bindings for HIP. Currently, only bindings for the AMD GPU backend of HIP are provided.

Known Issues

The hiprand Cython Module Causes Compiler Error

With all ROCm™ versions before and including version 5.6.0, compiling/using HIP Python's hiprand Cython module results in a compiler error.

The error is caused by the following statement in the C compilation path of <path_to_rocm>/hiprand/hiprand_hcc.h, which is not legal in C for aliasing a struct type:

typedef rocrand_generator_base_type hiprandGenerator_st;

Workaround (Requires Access to Header File): Edit Header File

For this fix, you need write access to the ROCm™ header files. Then, modify file <path_to_rocm>/hiprand/hiprand_hcc.h such that

typedef rocrand_generator_base_type hiprandGenerator_st;

becomes

typedef struct rocrand_generator_base_type hiprandGenerator_st;

ROCm™ 5.5.0 and ROCm™ 5.5.1

On systems with ROCm™ HIP SDK 5.5.0 or 5.5.1, the examples

• hip-python/examples/0_Basic_Usage/hiprtc_launch_kernel_args.py
• hip-python/examples/0_Basic_Usage/hiprtc_launch_kernel_no_args.py

abort with errors.

An upgrade to version HIP SDK 5.6 or later (or a downgrade to version 5.4) is advised if the showcased functionality is needed.

Unspecific

On certain Ubuntu 20 systems, we encountered issues when running the examples:

• hip-python/examples/0_Basic_Usage/hiprtc_launch_kernel_args.py
• hip-python/examples/0_Basic_Usage/rccl_comminitall_bcast.py

We could not identify the cause yet.
