[yt-users] volume rendering job dies

[Geoffrey So]

Hi all,

I'm starting to do some volume rendering of my 800 cube simulation, but the
job in the super computer just dies without any kind of error in the logs.
 The last few lines are:

I'm wondering if it is again an memory issue.  I ran this job with 16 nodes
with 16 cores per node and 4GB per core.  This setup is enough memory to do
the halo finding, I'm wondering what the memory requirements is for volume
rendering, and what's the biggest volume people have done up to date?

The script works on my tiny test problem of 64 cube:

If this isn't a problem people have with rendering larger volumes than
mine, then it might be a machine issue.  I haven't moved the data to
another super computer, but will try that next if others have done larger
volume rendering with no problems at all.
