Comment (by Roland Haas):

There are test cases for Lean now: https://einsteintoolkit.org/testsuite_results/index.php all tests for LeanBSSNMoL pass everywhere. However the thorn NPScalars has a failing test (teukolsky) on wheeler, stampede2-skx, shelob, golub, comet meaning it fails on most clusters and passes on most desktop systems. It could be a intel vs. gcc compiler issues, the test also passes on BW (gnu compiler but --ffast-math).
