Ramble is a multi-platform experimentation framework to increase exploration productivity and improve reproducibility. Ramble is capable of driving software installation, acquire input files, configure experiments, and extract results. It works on Linux, macOS, and many supercomputers.
Ramble can be used to configure a variety of experiments for applications. These can include anything from:
- Scientific parameter sweeps
- Performance focused scalaing studies
- Compiler flag sweeps
To install ramble and configure your experiment workspace, make sure you have Python, and Ramble’s dependencies are installed as per the dependency section below. Then:
$ git clone -c feature.manyFiles=true https://github.com/GoogleCloudPlatform/ramble.git
$ cd ramble/bin
$ ./ramble workspace create -d test_workspace -c ../examples/basic_hostname_config.yaml
Ramble’s python dependencies can be installed using the included requirements.txt file.
e.g.
$ pip install -r requirements.txt
Outside of these requirements, ramble requires an existing installation of spack for some application definition. See Spack’s documentation to install Spack.
For help with Ramble’s commands, run ramble help or ramble help --all.
For more information on concepts in Ramble, see Ramble’s Getting Started guide.
Example configuration files are also contained in the examples directory.
Ramble is an open source project. Questions, discussion, and contributions are welcome. Contributions can be anything from new packages to bugfixes, documentation, or even new core features.
Resources:
- Github Discussions: not just for discussions, also Q&A.
Contributing to Ramble is relatively easy. Just send us a
pull request.
When you send your request, make develop the destination branch on the
Ramble repository.
Your PR must pass Ramble's unit tests and documentation tests, and must be PEP 8 compliant. We enforce these guidelines with our CI process.
These tests can be run locally through test runners in the share/ramble/qa/ directory. Alternatively, pre-commit can be used to manage our git hooks. To install the hooks, simply run:
- pre-commit install
For additional requirements about contributing, including Google’s CLA, see our Contribution Guide.
Ramble's develop branch has the latest contributions. Pull requests
should target develop, and users who want the latest package versions,
features, etc. can use develop.
Each Ramble release series also has a corresponding branch, e.g.
releases/v0.1 has 0.1.x versions of Ramble, and releases/v0.2 has
0.2.x versions. We backport important bug fixes to these branches but
we do not advance the application definitions or make other changes that would
change the way experiments Ramble would create within a release branch.
So, you can base your Ramble deployment on a release branch subsequent updates
can be considered non-breaking.
The latest release is always available with the releases/latest tag.
Please note that Ramble has a Code of Conduct. By participating in the Ramble community, you agree to abide by its rules.
Many thanks go to Ramble's contributors.
