New issue 1268: enzo embedded parallel python/yt problem with gradient field https://bitbucket.org/yt_analysis/yt/issues/1268/enzo-embedded-parallel-pyth... Bodo Schwabe: I currently try to run enzo with embedded parallelized python/yt (Version = 3.4-dev Changeset = c941aa457bc3 (yt) tip) with the following user_script.py < http://paste.yt-project.org/show/6794/ > . It works fine on a single processor (mpirun -n 1 ...) but gives me the following error message for multiple processors <http://paste.yt-project.org/show/6795/ > . Regular derived_fields are working well, but gradient_fields aren't. Thank you very much for any suggestions.
