graphic dump on cluster

[Aron Ahmadia]

Hi Jianing,

I don't think the orion cluster is set up for the worker nodes to be able to
connect back to a remote workstation.  I would collect the data locally on
the master node, and use PETSC_VIEWER_DRAW_SELF.

Please double-check that the display code works on single-processor jobs,
that error looks like an X11 setup error as Matt notes.
