ROCprofiler-SDK: Application Profiling, Tracing, and Performance Analysis

Important

We are phasing out development and support for ROCTracer, ROCprofiler, rocprof, and rocprofv2 in favour of ROCprofiler-SDK and rocprofv3 in upcoming ROCm releases. Starting with the ROCm 6.4 release, only critical defect fixes will be addressed for older versions of the profiling tools and libraries. We encourage all users to upgrade to the latest version of the ROCprofiler-SDK library and the rocprofv3 tool to ensure continued support and access to new features.

Please note that we anticipate the end of life for ROCprofiler V1/V2 and ROCTracer within nine months after the ROCm 7.0 release, aligning with the Q1 2026.

Overview

ROCprofiler-SDK is AMD’s new and improved tooling infrastructure, providing a hardware-specific low-level performance analysis interface for profiling and tracing GPU compute applications. To see what's changed, Click Here

Note

The published documentation is available at ROCprofiler-SDK documentation in an organized, easy-to-read format, with search and a table of contents. The documentation source files reside in the rocprofiler-sdk/source/docs folder of this repository. As with all ROCm projects, the documentation is open source. For more information on contributing to the documentation, see Contribute to ROCm documentation.

Documentation

We make use of doxygen to generate API documentation automatically. The generated document can be found in the following path:

<ROCM_PATH>/share/html/rocprofiler-sdk

ROCM_PATH by default is /opt/rocm It can be set by the user in different locations if needed.

Build and Installation

git clone https://github.com/ROCm/rocprofiler-sdk.git rocprofiler-sdk-source
cmake                                         \
      -B rocprofiler-sdk-build                \
      -DCMAKE_INSTALL_PREFIX=/opt/rocm        \
      -DCMAKE_PREFIX_PATH=/opt/rocm           \
       rocprofiler-sdk-source

cmake --build rocprofiler-sdk-build --target all --parallel $(nproc)

To install ROCprofiler, run:

cmake --build rocprofiler-sdk-build --target install

Limitations

• Individual XCC mode is not supported.

• By default, PC sampling API is disabled. To use PC sampling. Setting the ROCPROFILER_PC_SAMPLING_BETA_ENABLED environment variable grants access to the PC Sampling experimental beta feature. This feature is still under development and may not be completely stable.

  • Risk Acknowledgment: By activating this environment variable, you acknowledge and accept the following potential risks:

    • Hardware Freeze: This beta feature could cause your hardware to freeze unexpectedly.
    • Need for Cold Restart: In the event of a hardware freeze, you may need to perform a cold restart (turning the hardware off and on) to restore normal operations. Please use this beta feature cautiously. It may affect your system's stability and performance. Proceed at your own risk.

  • At this point, we do not recommend stress-testing the beta implementation.

  • Correlation IDs provided by the PC sampling service are verified only for HIP API calls.

  • Timestamps in PC sampling records might not be 100% accurate.

  • For low PC-sampling frequencies with intervals < 65k cycles, a lot of error samples might be delivered. We're working on optimizing this to allow lower sampling frequencies.

• gfx11 and gfx12 architectures require a stable power state for counter collection. This includes AMD Radeon RX 7000 series GPUs and newer.

  # For device <N>. Use 'rocm-smi' or 'amd-smi monitor' to see device number.
  sudo amd-smi set -g <N> -l stable_std
  # After profiling, set power state back to 'auto'
  sudo amd-smi set -g <N> -l auto
