Welcome to AMD ROCm Platform

AMD ROCm is the first open-source software development platform for HPC/Hyperscale-class GPU computing. AMD ROCm brings the UNIX philosophy of choice, minimalism and modular software development to GPU computing.

AMD ROCm is built for scale; it supports multi-GPU computing in and out of server-node communication through RDMA. AMD ROCm also simplifies the stack when the driver directly incorporates RDMA peer-sync support.

The AMD ROCm Programming-Language Run-Time

The AMD ROCr System Runtime is language independent and makes heavy use of the Heterogeneous System Architecture (HSA) Runtime API. This approach provides a rich foundation to execute programming languages such as HCC C++ and HIP.

Important features include the following:

  • Multi-GPU coarse-grain shared virtual memory

  • Process concurrency and preemption

  • Large memory allocations

  • HSA signals and atomics

  • User-mode queues and DMA

  • Standardized loader and code-object format

  • Dynamic and offline-compilation support

  • Peer-to-peer multi-GPU operation with RDMA support

  • Profiler trace and event-collection API

  • Systems-management API and tools

Solid Compilation Foundation and Language Support

  • LLVM compiler foundation

  • HCC C++ and HIP for application portability

  • GCN assembler and disassembler

AMD ROCm gives developers the flexibility of choice for hardware and aids in the development of compute-intensive applications.
