Changelog for ROCm Systems Profiler

Full documentation for ROCm Systems Profiler is available at https://rocm.docs.amd.com/projects/rocprofiler-systems/en/latest/.

ROCm Systems Profiler 1.1.0 for ROCm 7.0

Added

  • Profiling and metric collection capabilities for VCN engine activity, JPEG engine activity, and API tracing for rocDecode, rocJPEG, and VA-APIs.
  • How-to document for VCN and JPEG activity sampling and tracing.
  • Support for tracing Fortran applications.
  • Support for tracing MPI API in Fortran.
  • Initial support for rocPD database output with the ROCPROFSYS_USE_ROCPD configuration setting.
  • By default, group "kernel dispatch" and "memory copy" events by HIP stream ID in Perfetto traces.
    • Add the "ROCPROFSYS_ROCM_GROUP_BY_QUEUE" configuration setting to group events by queue, instead.

Changed

  • Replaced ROCm SMI backend with AMD SMI backend for collecting GPU metrics.
  • ROCprofiler-SDK is now used to trace RCCL API and collect communication counters.
  • Updated the Dyninst submodule to v13.0.
  • Set the default value of ROCPROFSYS_SAMPLING_CPUS to none.

Resolved issues

  • Fixed GPU metric collection settings with ROCPROFSYS_AMD_SMI_METRICS.
  • Fixed a build issue with CMake 4.
  • Fixed incorrect kernel names shown for kernel dispatch tracks in Perfetto.
  • Fixed formatting of some output logs.
  • Fixed an issue where ROC-TX ranges were displayed as two separate events instead of a single spanning event.

ROCm Systems Profiler 1.0.2 for ROCm 6.4.2

Optimized

  • Improved readability of the OpenMP target offload traces by showing on a single Perfetto track.

Resolved issues

  • Fixed the file path to the script that merges Perfetto files from multi-process MPI runs. The script has also been renamed from merge-multiprocess-output.sh to rocprof-sys-merge-output.sh.

ROCm Systems Profiler 1.0.1 for ROCm 6.4.1

Added

Resolved issues

  • Fixed a build issue with Dyninst on GCC 13.

ROCm Systems Profiler 1.0.0 for ROCm 6.4.0

Added

  • Support for VA-API and rocDecode tracing.

  • Aggregation of MPI data collected across distributed nodes and ranks. The data is concatenated into a single proto file.

Changed

  • Backend refactored to use ROCprofiler-SDK rather than ROCProfiler and ROCTracer.

Resolved issues

  • Fixed hardware counter summary files not being generated after profiling.

  • Fixed an application crash when collecting performance counters with ROCProfiler.

  • Fixed interruption in config file generation.

  • Fixed segmentation fault while running rocprof-sys-instrument.

  • Fixed an issue where running rocprof-sys-causal or using the -I all option with rocprof-sys-sample caused the system to become non-responsive.

  • Fixed an issue where sampling multi-GPU Python workloads caused the system to stop responding.

ROCm Systems Profiler 0.1.1 for ROCm 6.3.2

Resolved issues

  • Fixed an error when building from source on some SUSE and RHEL systems when using the ROCPROFSYS_BUILD_DYNINST option.

ROCm Systems Profiler 0.1.0 for ROCm 6.3.1

Added

  • Improvements to support OMPT target offload.

Resolved issues

  • Fixed an issue with generated Perfetto files.

  • Fixed an issue with merging multiple .proto files.

  • Fixed an issue causing GPU resource data to be missing from traces of Instinct MI300A systems.

  • Fixed a minor issue for users upgrading to ROCm 6.3 from 6.2 post-rename from omnitrace.

ROCm Systems Profiler 0.1.0 for ROCm 6.3.0

Changed

  • Renamed Omnitrace to ROCm Systems Profiler.

Omnitrace 1.11.2 for ROCm 6.2.1

Known issues

  • Perfetto can no longer open Omnitrace proto files. Loading the Perfetto trace output .proto file in ui.perfetto.dev can result in a dialog with the message, "Oops, something went wrong! Please file a bug." The information in the dialog will refer to an "Unknown field type." The workaround is to open the files with the previous version of the Perfetto UI found at https://ui.perfetto.dev/v46.0-35b3d9845/#!/.
