hipify

HIP-Basic Hipify Example

Description

The hipify example demonstrates the use of HIP utility hifipy-perl to port CUDA code to HIP. It converts a CUDA .cu source code into a portable HIP .hip source code that can be compiled using hipcc and executed on any supported GPU (AMD or NVIDIA).

Application flow

1. The build system (either cmake or Makefile) first converts the main.cu source code into a HIP portable main.hip source code. It uses hipify-perl main.cu > main.hip command to achieve the conversion.
2. main.hip is then compiled using hipcc main.hip -o hip_hipify to generate the executable file.
3. The execuatable program launches a simple kernel that computes the square of each element of a vector.

Key APIs and Concepts

hipify-perl is a utility that converts CUDA .cu source code into HIP portable code. It parses CUDA files and produces the equivalent HIP portable .hip source file.
