[Paraview] reading in serial then distributing to parallel

[Moreland, Kenneth]

I think you've answered your own question.  Read the data into ParaView.  Run the D3 filter on it.  The output of the D3 filter will be distributed amongst the processes.

I am trying to start using Paraview in parallel for the first time and
have run into some trouble reading my data in when running in
parallel.

I am using XDMF and have unstructured data, which I have gathered from
the mailing list (thanks!) cannot be read in parallel without
restructuring the XML to use hyperslabs.

In scanning a set of slides from an online tutorial I saw the
following method suggested if you have a reader that isn't parallel:

* Only one node reads
* Whole data set must fit in one process' memory
* If you must, the D3 filter in Paraview will partition and
distribute

How would I go about getting the data read in by just one process and
then distributing it to other processors after read is complete?

Sorry if this question is a bit off the wall but I'm open to suggestions.
