Affinity Analyzer Functions

The tool checks software code to improve code quality and memory access performance.

When multiple modules are running concurrently, only one log level can be set at the same time.
If you move the tool to another location after you have already used the tool, a log configuration file read error occurs. You need to reinstall the tool or move the tool to its original installation location.

Prerequisites

You have installed the Affinity Analyzer tool. For details, see Installing the Tool.
If you have installed the tool using a compressed package, decompress the package and switch to the tool directory. Then run the command in ./ mode, for example, ./devkit advisor -v. If you have installed the tool using an RPM package, run devkit advisor -v. This section uses an RPM package as an example.

Command Function

Example

Run the following command to query all the parameter descriptions:

1	devkit advisor -h

Command output:

  Usage: devkit advisor [-h|--help] TASK [ARGS]

  The most commonly used devkit advisor sub tasks are:
    run-mode                Run the 64-bit running mode check task.
    addr-align              Run the address alignment of the structure task.
    cacheline               Run the cache line alignment check task.
    bc-gen                  Run the bc file generation task.
    mm-check                Run the memory mode check task.
    vec-check               Run the vectorization check task.
    affi-check              Run the affinity check task.
    matrix-check            Run the matricization check task.
    dr-check                Run the data race check task.
    precision               Run the precision analysis task.
    knet                    Run the K-NET analysis tools task.

  See 'devkit advisor TASK -h/--help' for more information on a specific task.

**Table 1** Function description
Subcommand	Function	Description	Supported Platform
run-mode	64-bit running mode check	Identifies the 32-bit applications to be ported to the 64-bit platform and provides modification suggestions. It supports GCC 4.8.5 to GCC 10.3.0.	Kunpeng
addr-align	Byte alignment check	Checks the byte alignment of structure variables in the source code.
bc-gen	BC file generation	Used for memory consistency check and vectorization check.
mm-check	Static memory consistency check	Checks for any memory inconsistency problems in static mode when C/C++ source code is running on the Kunpeng platform, and also provides check reports and memory barrier insertion suggestions.
vec-check	Vectorization check	Checks vectorizable code snippets and provides modification suggestions.
matrix-check	Matricization check	Checks matricizable code fragments and provides modification suggestions.
affi-check	Build affinity	Analyzes the content in Makefile and CMakeLists.txt that can be replaced with content in the Kunpeng library, and provides replacement suggestions and function repair.
cacheline	Cache line alignment check	Checks the 128-byte alignment of structure variables in the C/C++ source code to improve memory access performance.
dr-check	Dynamic memory consistency check	Checks for any memory inconsistency problems in dynamic mode when C/C++ source code is running on the Kunpeng platform, and also provides check reports and memory barrier insertion suggestions.
precision	Calculation precision analysis	Locates the precision differences of the Fortran, C, and C++ languages caused by x86 and Kunpeng instructions.	Kunpeng, x86
knet	Link latency detection	Provides the Kunpeng network detection and analysis functions, collects latency data of network protocol stacks, and analyzes network performance bottlenecks.	Kunpeng, x86
