[yt-dev] Fwd: [yt_analysis/yt] Volume Rendering Refactor (pull request #168)

[Christopher Moody]

Hi Matt,
Yep, this is an ART dataset. I had a node running with 12 (24 with HT)
cores at NASA Pleiades. It didn't go above 4% (=1/24) usage, which
indicates means it likely did not  use more than one core (but I
didn't tell it to). If there's a parallel version of the script I can
try it out tonight, and see the scaling.
