Result archive

Every time Jenkins runs the model, the inference results will be saved to probability.csv, which is archived by Jenkins.

Jenkins integration

The model is integrated into a master job. In this job, the model will first be run to decide whether the commit is likely to fail. If it is, then run gerrit_linux_clang_dbgutil first. If it fails, then return -1, else run the rest builds. If the model predicts that the commit is unlikely to fail, then run all the build in parallel like before.
