[Moreland, Kenneth]

I've never seen this before, so I am forwarding it on to the mailing
list.

so i now tried this:

python -c "import os; os.system('mpiexec -n 4 pvserver')"

and i still get the same error as shown below.  but now, it
looks like when i interact with the data, 2 of my 4 cpus are 
being used (the system is a dual opteron, so 4 cores total).
still, when actually computing the geometry, only one cpu
is being used, while in paraview2.6 i see all 4 processes as
active when the geometry is being computed.  maybe i am 
comparing apples to oranges, but it seems like something's
not quite right here.

thanks,
bryan

Unlike ParaView 2, the ParaView 3 client application cannot be run in
parallel.  Instead, you have to run pvserver in parallel and connect to
that.  In this mode, you still get all the parallel features of
ParaView.

hi,

i successfully compiled paraview3 beta with openmpi 1.0.2 by setting

SET(CMAKE_C_COMPILER mpicc)
SET(CMAKE_CXX_COMPILER mpicxx)

in my CMakeLists.txt file, and then running cmake like this:

cmake -DVTK_USE_MPI:BOOL=ON \
-DVTK__MPIRUN_EXE:FILEPATH=/path_to_openmpi/openmpi1.0.2/bin/ \
/path_to_paraview3_src/ParaView3/

and when i try to run

mpiexec -n 4 ./paraview

from within my paraview3 bin directory, i get 4 paraview windows rather 
than a single window running in parallel mode.  i have made sure the
path 
to the openmpi bin is on the top of my path, and the path to openmpi lib
is 
on the top of my ld_library_path environment variable, but still no
luck.  i 
have no trouble running paraview2.6 with this same command, built with
the same modifications to CMakeLists.txt and the cmake command line.

any help much appreciated,
bryan
