I took a look at this and see that it is correctly failing in test_machines.py around line 923. This checks for consistency between the total and per node process counts....

LMY engine has been untouched for a long time, but a discussion with Eric would be productive. In particular the "optimize subsets of parameters" approach is implemented there. I recall...

Painful as it is to note, LMY engine comes with a lot of baggage as well as its better algorithms. I think a clean implementation of any new algorithms without...

I believe the original idea was that this was never called from inside an OMP region. Can we require something similiar going forward? Do we have a use case for...

For consistency with the not-yet-discussed-or-decided tags for VMC, I suspect we'll want "total_samples" or similar and to enforce that the user not specify conflicting blocks/steps settings that conflict with it....

Thanks Luke. I totally agree that we have to have an automatic parallelization strategy soon, and sensible defaults. The code should do something pretty sensible and no user should have...

Yuri - If you have this build still setup please can you rerun a subset of the tests and report the summary here? We would like to see the output...

I would prefer not to fix the nightlies since it will hide the very clear user-facing problem
