I built the trilinos-capable version of fipy. It seems to work for serial
(even for a non-trivial case), but I am getting errors with more than one
processor with a simple call to globalValue(), which I was trying to use to
make a plot by gathering the results to procID==0
I used the latest git version of mpi4py and trilinos. Am I doing something
wrong (is there a different preferred way to gather things to a single
processor to save or make plots?) or do I need to use a specific version of
these packages and rebuild? It seems the function is expecting something
with a different interface or call structure.
