<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>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.<BR>

</SPAN></FONT><BLOCKQUOTE><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>I am trying to start using Paraview in parallel for the first time and<BR>
have run into some trouble reading my data in when running in<BR>
parallel.<BR>
<BR>
I am using XDMF and have unstructured data, which I have gathered from<BR>
the mailing list (thanks!) cannot be read in parallel without<BR>
restructuring the XML to use hyperslabs.<BR>
<BR>
In scanning a set of slides from an online tutorial I saw the<BR>
following method suggested if you have a reader that isn't parallel:<BR>
<BR>
• Only one node reads<BR>
• Whole data set must fit in one process’ memory<BR>
• If you must, the D3 filter in Paraview will partition and<BR>
distribute<BR>
<BR>
How would I go about getting the data read in by just one process and<BR>
then distributing it to other processors after read is complete?<BR>
<BR>
Sorry if this question is a bit off the wall but I'm open to suggestions.<BR>
