AMG regression test fails with three levels #324
Comments
This was fixed in #325 by changing the test. The root cause is unclear except that using too many AMG levels potentially causes memory-related issues. |
@sseraj, if there is a known issue, I would prefer to either document it somewhere in the docs or create a separate issue. |
This issue has all the relevant information, so maybe it is best to just reopen this |

Description
Nightly docker integration tests on the
u22-gcc-ompi-stable
x86 image is failing on the AMG test (see here). This seems to be a result of a newly merged PR #235.The
test_amg.py:TestAMGReal_2_different_levels_and_iterations.test_convergence
AMG regression test is failing to converge.Steps to reproduce issue
This can be reproduced with the failed image pushed to DockerHub, i.e.,
mdolab/public:u22-gcc-ompi-stable-amd64-failed
(Digest: sha256:76e6eb4be1c823744ec7cfc46fa38e5edc9897b8cf9d54dc08d208cd5db1d2f2
). Using the image, download the input test files, and run only the AMG regression teststestflo -s -v -n 1 test_amg.py
.Using the previous commit
git checkout 559a1deee07126c521e7a2e18f3968dd0ef7b061
, rebuilding and pip installing, then all AMG tests do pass successfully.Current behavior
Currently, the case does not converge and test fails.
Expected behavior
Case should converge and test pass.
