New issue 457: Ellipsoid objects and fake_random_pf
https://bitbucket.org/yt_analysis/yt/issue/457/ellipsoid-objects-and-fake_random_pf

Stephen Skory:

The ellipsoid object doesn't appear to be working correctly with the fake_random_pf and differing nprocs.

    from yt.mods import *
    from yt.testing import *
    pf1 = fake_random_pf(64, nprocs = 1)
    pf8 = fake_random_pf(64, nprocs = 8)
    ell1 = pf1.h.ellipsoid([0.35]*3, 0.05, 0.05, 0.05, np.array([0.1]*3),np.array([0.1]*3))
    ell8 = pf8.h.ellipsoid([0.35]*3, 0.05, 0.05, 0.05, np.array([0.1]*3),np.array([0.1]*3))
    print 'these should be the same:', ell1.volume() == ell8.volume(),  ell1.volume(), ell8.volume()

gives:

    these should be the same: False 0.0145034790039 0.0140838623047

I'm assigning this to myself, but I'm going to actually see about asking Geoffery So to take a look at it.
