The ROCm stack is essential for developers targeting AMD GPUs, but its layered architecture can be confusing. This article provides a conceptual mapping of three key components: HIP (Heterogeneous-Compute Interface for Portability), which allows CUDA-like code to run on AMD hardware; ROCr, the runtime system managing device execution; and libhsakmt, the kernel module for low-level hardware access. Understanding these layers helps developers optimize performance and port code efficiently. As AMD gains traction in HPC and AI, mastering ROCm becomes increasingly valuable. This reference guide is ideal for systems programmers and GPU developers looking to deepen their knowledge of AMD's ecosystem.
