<div style="FONT-FAMILY:Verdana">Hi all,</div>
<div>
<div>
<div> When I run the Catalyst example
CxxMultiPieceExample with parallel Live Data Visualization, I get errors
"Cannot send vtkMultiPieceDataSet" "Socket error in call to send.
Broken pipe" as the figure shown below.</div>
<div>I just modify the SampleScripts/feslicescript.py slightly by changing
the paramter of coprocessor.EnableLiveVisualization() from False to
True.</div>
<div> </div>
<div>[My paraview version 4.0.0, compiled with PARAVIEW_USE_MPI on]</div>
<div> </div>
<div>The error occurs when clicking on the Live Data icons in the PipeLine
panel, shown in Fig.1 . As I click it, both pvserver and paraview client
are crashed, while the simulation code continues except printing the
error information once as mentioned before, shown in Fig.2. If I dont force
it to quit, the simulation runs well and generates proper coprocessing snapshots
in fullgrid_* and slice_* folders.</div>

<div>Fig 1. Both pvserver and paraview crash when click</div>
<div> </div>
<div>To make things clear, I insert some printf in the code
FEAdaptor.cxx and found that the errors are generated when calling
Processor->CoProcess().</div>
<div>For the sake of simplicity, I run the program with only one process in one
node. </div>
<div> </div>
<div>mpiexec -np 1 pvserver</div>
<div>paraview #and then connect to localhost:11111 and then connect to
catalyst.</div>
<div>mpiexec -np 1 ./FEDriver Sample/feslicescript.py</div>

<div>More information are as follows.</div>
<div style="TEXT-INDENT:2em"> </div>
<div style="TEXT-INDENT:2em">Here is why I run this example.</div>
<div style="TEXT-INDENT:2em">I have an application in which I wanna do a
parallel Live Visualization of a volume data, and is quite similar to the
Catalyst example named CxxImageDataExample. But I failed to make the
sub-images composited correctly by setting the extent and whole extent,
both in the example code [shown in Fig.3] and my application code. It
shows the error of "RegionIDs cannot be 0". Thus I think I need a
vtkMultiBlockDataSet and vtkMultiPieceDataSet to manage my volume data and its
division, it this true?</div>
<div style="TEXT-INDENT:2em"> </div>
<div style="TEXT-INDENT:2em">Would you please take some minutes to do a simple
test of these two examples to see is it running correct on your
machines?</div>
<div style="TEXT-INDENT:2em"> </div>
<div style="TEXT-INDENT:2em">Many thanks to you!</div>
