[vtkusers] Problem running DistributedData.cxx

[Cally K]

hi, I have some problem running DistributedData.cxx ( in the
parallel/testing folder )

I have compiled the compiled the DistributedData using this Cmakelists.txt

PROJECT (DistributedData.cxx)

FIND_PACKAGE(VTK REQUIRED)
IF(NOT VTK_USE_RENDERING)
  MESSAGE(FATAL_ERROR "Example ${PROJECT_NAME} requires VTK_USE_RENDERING.")
ENDIF(NOT VTK_USE_RENDERING)
INCLUDE(${VTK_USE_FILE})

ADD_EXECUTABLE(DistributedData DistributedData.cxx)
TARGET_LINK_LIBRARIES(DistributedData vtkCommon vtkDICOMParser vtkexpat
vtkfreetype vtkftgl vtkGenericFiltering vtkHybrid vtkImaging vtkNetCDF
vtkIO.a vtkGraphics vtkRendering vtkFiltering vtkWidgets vtkParallel)



I, however have problem running the executable, I loaded both the executabe
into 2 machines

Machine A ( 192.168.10.20 )
Machine B ( 192.168.10.21)

and I am accesing it from my computer( DHCP enabled )

after running the following command - I use OpenMPI

mpirun -hostfile myhostfile -np 2 -bynode ./DistributedData

and I keep getting these errors

ERROR: In

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


This is what I want to do

my mpirun should run on 2 machines ( A and B ) and I should be able to view
the output ( on my PC ),
are there any specfic commands to use.
