Motivation / Current Behaviour

The ABM is parallelized using OpenMP but the Unit Tests are only executed single threaded. So there is no test that parallelized ABM produces the same results as sequential.

Enhancement description

• Add a multithreaded runner
• Add a CI job that runs the unit tests with OPM_NUM_THREADS > 1, exact number depends on unit tests and runner
