<p>hi, I have some problem running DistributedData.cxx ( in the parallel/testing folder )</p>
<p>I have compiled the compiled the DistributedData using this Cmakelists.txt</p>
<p>PROJECT (DistributedData.cxx)</p>
<p>FIND_PACKAGE(VTK REQUIRED)<br>IF(NOT VTK_USE_RENDERING)<br> MESSAGE(FATAL_ERROR "Example ${PROJECT_NAME} requires VTK_USE_RENDERING.")<br>ENDIF(NOT VTK_USE_RENDERING)<br>INCLUDE(${VTK_USE_FILE})</p>
<p>ADD_EXECUTABLE(DistributedData DistributedData.cxx)<br>TARGET_LINK_LIBRARIES(DistributedData vtkCommon vtkDICOMParser vtkexpat vtkfreetype vtkftgl vtkGenericFiltering vtkHybrid vtkImaging vtkNetCDF vtkIO.a vtkGraphics vtkRendering vtkFiltering vtkWidgets vtkParallel)</p>
<p> </p>
<p>I, however have problem running the executable, I loaded both the executabe into 2 machines</p>
<p>Machine A ( <a href="http://192.168.10.20">192.168.10.20</a> )<br>Machine B ( <a href="http://192.168.10.21">192.168.10.21</a>)</p>
<p>and I am accesing it from my computer( DHCP enabled )</p>
<p>after running the following command - I use OpenMPI</p>
<p>mpirun -hostfile myhostfile -np 2 -bynode ./DistributedData</p>
<p>and I keep getting these errors</p>

<p> </p>
<p>I am not really sure if it is a VTK error or an openmpi error, maybe I am not doing the xforwading properly, I am posting this to the openmpi group also, but has anyone ever encountered the same problem, it works fine on one pc, and I read the mailing list but I just don't know if my prob is similiar to their, I even tried changing the DISPLAY env</p>
<p><br>This is what I want to do</p>
<p>my mpirun should run on 2 machines ( A and B ) and I should be able to view the output ( on my PC ),<br>are there any specfic commands to use.</p>
