NEW, AMD uProf 3.5 is now available Jan 17, 2022 Downloads Documentation
AMD uProf (“MICRO-prof”) is a software profiling analysis tool for x86 applications running on Windows, Linux and FreeBSD operating systems and provides event information unique to the AMD “Zen”-based processors. AMD uProf enables the developer to better understand the limiters of application performance and evaluate improvements.
AMD uProf offers:
- Performance Analysis – to identify runtime performance bottlenecks of the application.
- System Analysis – to monitor system performance metrics.
- Power Profiling – to monitor thermal and power characteristics of the system.
- Energy Analysis – to identify energy hotspots in the application (Windows only).
AMD uProf can effectively be used to:
- Analyze the performance of one or more processes or the entire system.
- Characterize the performance bottlenecks (hotspots & micro-architecture) in the source code.
- Identify ways to optimize the source code for better performance and power efficiency.
- Examine the behavior of kernel, drivers, and system modules.
- Analyze thread concurrency.
- Observe frequency, thermal and power characteristics (Power profiling).
- Observe system metrics, such as Instructions Per Clock (IPC), core effective frequency, and memory bandwidth.
What’s New in AMD uProf 3.5
- CPU Profiling GUI – Timeline for CPU Profile events, profile duration filter in timeline, bottom-up view of callstack samples, thread level callgraph support, and thread level flamegraph support.
- Holistic Analysis View – Analyze CPU, GPU, and OS together in GUI on Linux platforms. In holistic analysis view, events that can be analyzed are OS scheduling events, System calls, POSIXthread sync APIs, GPU activities, and MPI API event tracing.
- OS Tracing – Operating System event analysis on Linux are thread state analysis, kernel block I/O analysis, pagefault analysis, and memtrace (memory alloc/dealloc) analysis.
- MPI Tracing – HPC Analysis on Linux by tracing of MPI applications based on MPICH and derivatives.
- GPU Tracing – GPU trace analysis on Linux for AMD Instinct™ MI100 and MI200 accelerators.
- GPU Profiling – GPU kernel dispatch analysis on Linux for AMD Instinct™ MI100 and MI200 accelerators.
- AMDuProfSys – A new system analysis tool captures system information that can be key to debugging issues.
