ReFrame is a powerful framework for writing system regression tests and benchmarks, specifically targeted to HPC systems. The goal of the framework is to abstract away the complexity of the interactions with the system, separating the logic of a test from the low-level details, which pertain to the system configuration and setup. This allows users to write portable tests in a declarative way that describes only the test's functionality.
Tests in ReFrame are simple Python classes that specify the basic variables and parameters of the test. ReFrame offers an intuitive and very powerful syntax that allows users to create test libraries, test factories, as well as complete test workflows using other tests as fixtures. ReFrame will load the tests and send them down a well-defined pipeline that will execute them in parallel. The stages of this pipeline take care of all the system interaction details, such as programming environment switching, compilation, job submission, job status query, sanity checking and performance assessment.
Please visit the project's documentation page for all the details!
ReFrame is fairly easy to install. All you need is Python 3.6 or above and to run its bootstrap script:
git clone https://github.com/reframe-hpc/reframe.git
cd reframe
./bootstrap.sh
./bin/reframe -VIf you want a specific release, please refer to the documentation page.
You can optionally run the framework's unit tests with the following command:
./test_reframe.py -vNOTE: Unit tests require a POSIX-compliant C compiler (available through the cc command), as well as the make utility.
You may build the documentation of the master manually as follows:
./bootstrap.sh +docs
For viewing it, you may do the following:
cd docs/html
python3 -m http.server
The documentation is now up on localhost:8000, where you can navigate with your browser.
The framework comes with an experimental library of tests that users can either run from the command line directly or extend and fine tune them for their systems. See here for more details.
The ReFrame HPC community Github page provides mirror forks of interesting ReFrame test repositories maintained by various sites or projects. You can use those tests as an additional guidance to implement your own tests.
If you maintain a public test repository and you would like it to be listed in the community page, feel free to open an issue or contact us through Slack.
You can get in contact with the ReFrame community in the following ways:
