@schlaicha @keerthirk1995 any progress from your side? This is still a problem for our CI: pipeline 359192 (issue #4851).
from espresso.
I won't be able look into this in the coming weeks again. @keerthirk1995 could you have a look at what is the non-deterministic part?
I assume it is the steepest descent which can behave differently.
So here is what I would try:
- do the steepest descent as done now
- as this might still end up in a very unfavourable configuration add some warm-up steps in a loop with the langevin friction set significantly higher (~1?):
- start with a small timestep, like 0.001
- run ~200-1000 steps
- increse timestep (0.002, 0.005, 0.01, ...) until you reach the simulation timestep
- then, reduce the langevin friction again to enhance diffusion/equilibration
The number of integration steps and timestep increment needs to be adjusted a little...
Let me know if you have questions!

Tutorial part 1 is now failing too: pipeline 359826 (issue #4857).

This issue has paralyzed the ESPResSo project for a month. The issue tracker was flooded with notifications about this tutorial failing CI. We didn't detect in time an issue from an Ubuntu update on the CI runners because its notifications were drowned in the tutorial notifications, and now all CI runners have an Ubuntu version where the ASAN library is broken. The last merge commit on the python branch at the time of writing is 7ad0534, timestamped a month ago, because we cannot merge a PR if CI is failing, and CI was failing daily due to both ASAN and the tutorial being broken.
