Source: dolfin Followup-For: Bug #920546 The flaky test has been nasty the last couple of days. Always the C++ MPI demos timing out, each time on a different demo. The MPI python demos (usually) run fine. Presumeably some unresolved race condition.
2019.1 is now released (currently in experimental), so over time we'll see if the problem is resolved in the new version or not. The dolfin tests (even when successful) are shame-listed as "slow running" by debci, taking about 1:15 hr to complete. The tests are comprehensive, we could of course run a subset of them if it were important to run the tests more quickly. Is there an autopkgtest option to distingush between "normal" and "slow" tests, so the test daemon can make its own decision whether to run all of them or not? I've added C++ unit tests now. They only add a minute or less. I don't think the "slow" timing of the tests is related to the C++ MPI timeouts (the python tests are the slow ones). So an audit of the tests (when successful): C++ unit tests (serial): 2 sec C++ demos (serial): 135 sec = 2.3 min C++ demos (MPI): 415 sec = 6.9 min (flaky timeouts) python unit tests (serial): 1395 sec = 23.3 min python unit tests (MPI): 622 sec = 10.4 min python demos (serial): 665 sec = 11 min python demos (MPI): 634 sec = 10.6 min total run time = 3868 sec = 65 min = 1 hr 5 min Audit of flaky timeouts (C++ MPI demos back to March 1 2019): demo_poisson-disc_mpi demo_bcs_mpi demo_submesh_mpi demo_nonmatching-interpolation_mpi demo_auto-adaptive-navier-stokes_mpi demo_eigenvalue_mpi demo_elasticity_mpi demo_elastodynamics_mpi demo_singular-poisson_mpi demo_sym-dirichlet-bc_mpi demo_mixed-poisson_mpi demo_spatial-coordinates_mpi demo_advection-diffusion_mpi No obvious pattern.
