[yt-dev] yt-3.0 parallel_capable

[Nathan Goldbaum]

Hi Britton,

What happens when you call yt.enable_parallelism() at the top of the script?

There were some adjustments to the way parallelism works related to
YTEP-0019.  See this PR:
https://bitbucket.org/yt_analysis/yt/pull-request/729/ytep-0019/diff

Do you have a short test script I can try running over here to confirm the
issue?

-Nathan
