ERT - Ensemble based Reservoir Tool - is designed for running ensembles of dynamical models such as reservoir models, in order to do sensitivity analysis and data assimilation. ERT supports data assimilation using the Ensemble Smoother (ES), Ensemble Smoother with Multiple Data Assimilation (ES-MDA) and Iterative Ensemble Smoother (IES).
When cancelling the experiment, all the realizations are supposed to be killed and confirmed killed. Nevertheless, we've got many log statements:
which is produced here: https://github.com/equinor/ert/blob/314d52cb24ba54b261c5a714c665982616011b8a/src/ert/scheduler/scheduler.py#L138
This might imply that
15seconds of waiting for the jobs to be killed is not long enough. This needs more investigation though.
