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.

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.

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

• How-to document for network performance profiling for standard Network Interface Cards (NICs).

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/#!/.
