AMD CodeAnalyst Performance Analyzer for Linux is an open source, front-end graphical user interface to Oprofile. The graphical user interface simplifies the process of collecting performance data and enhances data analysis. Profiles are shown in both tabular and chart form. Users can drill down from system-level processes and modules to source code or instructions.

AMD CodeAnalyst taps into the performance monitoring capabilities of AMD processors. AMD CodeAnalyst supports the collection of up to 32 performance events in a single test run. This capability makes it easier to stage performance experiments. AMD CodeAnalyst also supports Instruction-Based Sampling (IBS) – a new performance measurement technique available on AMD Family 10h processors.

Oprofile with Support for the Latest AMD Processors

AMD CodeAnalyst also provides Oprofile command line tools (i.e. opcontrol, opreport, and opannotate) with up-to-date support for the latest AMD processors.  Developers and performance engineers can get started with events and other features that are not yet available in the mainstream Oprofile distribution.
