New issue 754: Bug when creating timeseries in parallel but not serial in unit refactor https://bitbucket.org/yt_analysis/yt/issue/754/bug-when-creating-timeseries-...
When I run the following script to create a time series (using the simulation object), it runs fine with a single processor, but it fails when running with multiple processors. This works fine in yt 2.x, and it appears to be due to a units comparison in the unit refactor.
Success when called: $ mpirun -np 1 python script.py --parallel
Failure when called: $ mpirun -np 2 python script.py --parallel

I did end up finding a way around this, so it isn't a dire need to have this working, but I thought it might be indicative of some larger problem in the code.
