GENIE Versions
This page records the details and meanings of tags in the GENIE code repository.

The GENIE code base is tagged at various junctures with the following naming convention:

rel---

HEAD
Note that you can think of the repository's HEAD version as a kind of model beta version. Any code commited to the repository should have been tested against the suite of short tests. These tests are designed to run easily and quickly--to encourage people to use them. They also aim to exercise as much of the model code in the short time that they take to run. However, you will appreciate that there is an inherent tradeof. To supplement the short tests, a longer suite of tests is run as part of the nightly build.

Released versions are scrutinised a good deal more than the automated tests can do. For example, the model is typically subjected to a large number of tuning runs, exercising the model across large portions of the space of tunable parameters. In addition to the elevated quality control, you will also have a set of optimised parameters to use in conjunction with a stable version of the model. (The is no guarantee that such a parameter set will be optimal for another version of the model's source code.)

So, in summary, it is far better to use a released version of the model than the HEAD.
