AMD CodeAnalyst was a GUI-based code profiler for x86 and x86-64-based machines. CodeAnalyst has similar look and feel on both Linux and Microsoft Windows platforms. CodeAnalyst uses specific hardware profiling techniques which are designed to work with AMD processors, as well as a timer-based profiling technique which does not require specific hardware support; this allows a subset of profiling features to work on non-AMD processors, such as Intel processors.[2]

As of March 2013, CodeAnalyst has been replaced by AMD CodeXL.[3]


Code optimization

CodeAnalyst is built on OProfile for the Linux platform and is available as a free download. The GUI assists in various kinds of code profiling including time based profiling, hardware event-based profiling, instruction-based profiling and others. This produces statistics about details such as time spent in each subroutine which can be drilled down to the source code or instruction level. The time taken by the instructions can be indicative of stalls in the pipeline during instruction execution. Optimization could be as simple as reordering the instructions for maximum utilization of a data line cache or altering/removing the branches and loops so that the maximum number of execution units(Load/Store units, ALU, FP execution unit...) are utilized in parallel.

Support for PERF was added in CodeAnalyst 3.4, allowing users to choose between OProfile and PERF as the profiling backend.[4]

Instruction-Based Sampling

CodeAnalyst supports IBS (Instruction-Based Sampling) that was introduced in Family 10h AMD processors (Barcelona). With IBS support, CodeAnalyst can more precisely identify instructions that cause pipeline stalls and cache misses.[5]

Open-source

The Linux version of CodeAnalyst is available under GNU General Public License 2.0.[6]

CodeAnalyst also uses other open-source components, including the Qt framework, libdwarf, libelf, and the Binary File Descriptor library.

gollark: I think hydro at least said to not use it.
gollark: kMarx is deprecated, Xenon is used now.
gollark: Which bit? I'm not sure about the user experience bit, but it's harder to get more CPU than it is more GPU.
gollark: Also, decimal points would likely break basically everything in existence.
gollark: *But* would also probably make the user experience worse than just using a bit of the GPU.
