HIP documentation

HIP is a C++ runtime API and kernel programming language designed for AMD GPUs. By providing an interface closely aligned with NVIDIA CUDA, HIP allows developers to write portable applications and efficiently migrate existing CUDA code to AMD platforms. Additional information is available in What is HIP?

Developers who require a unified, book‑style reference for ROCm and HIP can consult the AMD ROCm Programming Guide. It aggregates documentation from the ROCm portal and organizes it into a structured format optimized for in‑depth study and offline access in both PDF and HTML. Additional details are available in the AMD ROCm Programming Guide.

Note

HIP API 7.0 introduces changes to make it align more closely with NVIDIA CUDA. These changes are incompatible with prior releases, and might require recompiling existing HIP applications for use with the ROCm 7.0 release. For more information, see HIP API 7.0 changes.
