AMD μProf

NEW, AMD uProf 5.3 is now available (May 12, 2026)

AMD uProf (“MICRO-prof”) is a performance analysis tool-suite for x86 based applications running on Windows, Linux, and FreeBSD operating systems. It provides performance metrics for AMD “Zen”-based processors and AMD Instinct™ MI Series accelerators. AMD uProf enables developers better understand performance bottlenecks, optimization scope, and evaluate improvements.

AMD uProf Features

• Performance Analysis - Identify runtime performance bottlenecks in applications
• System Analysis – Monitor system-level performance metrics
• Power Profiling – Track thermal and power characteristics of the system
• Remote Profiling – Connect to remote Linux systems from a Windows host, initiate data collection and translation on the remote system, and view results in the local GUI
• Analyze workload behavior, thread concurrency, and system-wide performance
• Detect hotspots and micro-architectural issues in source code
• Visualize GPU and heterogeneous application behavior on MI systems

What’s New in AMD uProf 5.3

Performance & Scalability Improvements

• Optimized translation speed in CPU Profiling for modules with inline functions
• Significant reduction in Python profiling overhead for long profile runs
• Optimized database storage and reduced translation overhead for Hotspots and Threading runs
• Reduced overall reporting time for large sessions
• Optimized report generation for OpenMP, MPI, and hybrid workloads
• Integration of DuckDB as a high‑performance database backend, replacing SQLite as the default database (SQLite remains available for backward compatibility)

GUI & Visualization Enhancements

• Multiple enhancements to AMDuProfPCM HTML Report
• Enabled Linux Timeline visualization for function tracing sessions in the GUI
• Added Thread Name and TID tooltip in the All Thread Timeline with no truncation for improved thread‑level observability
• Added Per‑Rank analysis of MPI data in the GUI
• Optimized translation and reporting time in the GUI

CLI & Workflow Usability

• Added an option to AMDuProfCLI to allow users to specify a Session Name
• Added new CLI option --collect-thread on Linux to collect wait‑time data for a specific thread

Metrics & Platform Support

• Added a new IBS metric: IBS_[LD,ST]_L1_DTLB_REFILL_LAT for Zen 4 / Zen 5 platforms to analyze TLB‑related load and store bottlenecks
• Added PCIe metrics for Zen 3 server platforms in AMDuProfPCM

Virtualization & System Support

• vIBS: Enabled IBS support in virtualized environments using the KVM hypervisor
• Packaged the AMDSystemCheck utility on Linux to report OS, BIOS, and platform topology details

MPI, OpenMP & Parallel Profiling Improvements

• Expanded Fortran name mangling coverage in MPI tracing agents
• Corrected OpenMP imbalance and synchronization calculations
• Improved accuracy of MPI timing and rank‑level reporting
• Prevented silent loss of MPI trace visibility in mixed‑language applications
• Introduced Unused Threads metric in inefficiency metrics to handle profile runs with varying thread counts

For a complete list of features added in this release, refer to the release notes.
