New issue 888: find_max() returning odd values https://bitbucket.org/yt_analysis/yt/issue/888/find_max-returning-odd-values Brian O'Shea: I am using yt-3, and am running find_max() on a series of Enzo cosmological datasets (see link to z=0 dataset below). Using the script linked to below, The field matter_overdensity produces unreasonably large values (~1e+40 - 1e+302, unitless) for later data outputs (see output linked to below), when the script is run in parallel using the command "mpirun -np 16 python dmdensity.py --parallel". The field "density" produces sensible results in parallel, and both matter_overdensity and density produce sensible results when run in serial. script: http://paste.yt-project.org/show/5073/ output: http://paste.yt-project.org/show/5074/ z=0 dataset: http://galactica.pa.msu.edu/~bwoshea/data/datasets/RD0006.tar
