Hi every<br>
I have four machines (node1-node4) installed mpich1.2.7 and have passed "cpi"test programme.<br>
When I try the vtk parallel processing example ParallelIso.cxx I get try troubles.<br>
I run the command <br>
"mpirun -np 1 ParallelIso" the result is correct<br>
<br>
BUT when I run <br>
"mpirun -np 2 ParallelIso" I get these error message<br>
<br>
ERROR: In /usr/local/vtk/IO/vtkImageReader2.cxx, line 531<br>
vtkImageReader (0x9109790): Initialize: Could not open file ../../../../VTKData/Data/headsq/quarter.46<br>
<br>
and only half part of images are rendered in the windows, when 3 nodes take in part only one third part are rendered<br>
I think this may be vtkdata sharing promble but I don't know how to sovle it.<br>
My VTK_DATA_ROOT=/home/mpiuser/prog_mirror/vtkdata witch is NFS share disk between node1-4<br>
<br>
