This is a fork of Porting advisor, an open source project by the ARM High Performance Computing group. Originally, it was coded as a Python module that analyzed some known incompatibilities for C and Fortran code.
It is a command line tool that analyzes source code for known code patterns and dependency libraries. It then generates a report with any incompatibilities with our Graviton processors. This tool provides suggestions of minimal required and/or recommended versions to run on Graviton instances for both language runtime and dependency libraries. It can run on non-ARM based machines (no Graviton processor needed). This tool does not work on binaries, just source code. It does not make any code modifications, it doesn’t make API level recommendations, nor does it send data back to AWS.
PLEASE NOTE: Even though we do our best to find known incompatibilities, we still recommend to perform the appropriate tests to your application on a Graviton instance before going to Production.
This tool scans all files in a source tree, regardless of whether they are included by the build system or not. As such it may erroneously report issues in files that appear in the source tree but are excluded by the build system. Currently, the tool supports the following languages/dependencies:
- Python 3+
- Python version
- PIP version
- Dependency versions in requirements.txt file
- Java 8+
- Java version
- Dependency versions in pom.xml file
- JAR scanning for native method calls (requires JAVA to be installed)
- Go 1.11+
- Go version
- Dependency versions on go.mod file
- C, C++, Fortran
- Inline assembly with no corresponding aarch64 inline assembly.
- Assembly source files with no corresponding aarch64 assembly source files.
- Missing aarch64 architecture detection in autoconf config.guess scripts.
- Linking against libraries that are not available on the aarch64 architecture.
- Use of architecture specific intrinsic.
- Preprocessor errors that trigger when compiling on aarch64.
- Use of old Visual C++ runtime (Windows specific).
- The following types of issues are detected, but not reported by default:
- Compiler specific code guarded by compiler specific pre-defined macros.
- The following types of cross-compile specific issues are detected, but not reported by default.
- Architecture detection that depends on the host rather than the target.
- Use of build artifacts in the build process.
For more information on how to modify issues reported, use the tool’s built-in help:
./porting-advisor-linux-x86_64 -–helpIf you run into any issues, see our CONTRIBUTING file.
By using this option, you don't need to worry about Python or Java versions, or any other dependency that the tool needs. This is the quickest way to get started.
Pre-requisites
- Docker or containerd + nerdctl + buildkit
Build container image
NOTE: if using containerd, you can substitute docker with nerdctl
docker build -t porting-advisor .NOTE: on Windows you might need to run these commands to avoid bash scripts having their line ends changed to CRLF:
git config core.autocrlf false
git reset --hardRun container image
After building the image, we can run the tool as a container. We use -v to mount a volume from our host machine to the container.
We can run it directly to console:
docker run --rm -v my/repo/path:/repo porting-advisor /repoOr generate a report:
docker run --rm -v my/repo/path:/repo -v my/output:/output porting-advisor /repo --output /output/report.htmlWindows example:
docker run --rm -v /c/Users/myuser/repo:/repo -v /c/Users/myuser/output:/output porting-advisor /repo --output /output/report.htmlPre-requisites
- Python 3.10 or above (with PIP3 and venv module installed).
- (Optionally) Open JDK 17 (or above) and Maven 3.5 (or above) if you want to scan JAR files for native methods.
Enable Python Environment
Linux/Mac:
python3 -m venv .venv
source .venv/bin/activatePowershell:
python -m venv .venv
.\.venv\Scripts\Activate.ps1Install requirements
pip3 install -r requirements.txtRun tool (console output)
python3 src/porting-advisor.py ~/my/path/to/my/repoRun tool (HTML report)
python3 src/porting-advisor.py ~/my/path/to/my/repo --output report.htmlPre-requisites
- Python 3.10 or above (with PIP3 and venv module installed).
- (Optionally) Open JDK 17 (or above) and Maven 3.5 (or above) if you want the binary to be able to scan JAR files for native methods.
The build.sh script will generate a self-contained binary (for Linux/MacOS). It will be output to a folder called dist.
By default, it will generate a binary named like porting-advisor-linux-x86_64. You can customize generated filename by setting environment variable FILE_NAME.
./build.shFor Windows, the Build.ps1 will generate a folder with an EXE and all the files it requires to run.
.\Build.ps1Running the binary
Pre-requisites
Once you have the binary generated, it will only require Java 11 Runtime (or above) if you want to scan JAR files for native methods. Otherwise, the file is self-contained and doesn't need Python to run.
Default behaviour, console output:
$ ./porting-advisor-linux-x86_64 ~/my/path/to/my/repoGenerating HTML report:
$ ./porting-advisor-linux-x86_64 ~/my/path/to/my/repo --output report.htmlGenerating a report of just dependencies (this creates an Excel file with just the dependencies we found on the repo, no suggestions provided):
$ ./porting-advisor-linux-x86_64 ~/my/path/to/my/repo --output dependencies.xlsx --output-format dependencies./dist/porting-advisor-linux-x86_64 ./sample-projects/
