100% CPU is normal/unavoidable, see http://paraview.org/Wiki/Setting_up_a_ParaView_Server#Server_processes_always_have_100.25_CPU_usage

If anyone knows how to NOT get this behavior, I’d like to hear how ☺

Oh my freaking god :)
After 3 hours of building Qt from sources and then 1 hour for Paraview I finally got pvserver to work. My longest linux software installation challenge so far :)

My only concern is each pvserver consumes 100% of CPU when no clients connected and it's idle. Is it normal? Unfortunately that's not what I expected.

Your Qt is not built with WebKit. Did you build Qt from source as well?

OK, new version didn't help. So I tried to compile from source, again. After spending another 3 hrs I got this error. I thing that's the error I got last time.

How can I get that header file, or whatever <QWebPage> is.

There are on http://www.paraview.org/paraview/resources/software.php,
however you have to use mpiexec provided by the package.

Actually, I didn't build anything, because when I tried it took 3 hours and
threw some error on 89%, so I just gave up and downloaded ready-to-go
version. I believe that's the reason then. Is there any MPI enabled
precompiled distro for linux?

Verify that the paraview is built with mpi enabled (PARAVIEW_USE_MPI
cmake flag must be ON). In most likelihood, it's not.

Hi all,

I have issues with running parallel pvserver on linux machine. When I try
this `mpirun -np 3 ./pvserver` I get error `vtkServerSocket (0xe09640):
Socket error in call to bind. Address already in use.` for every process but
first.  I believe it's because each of `pvserver` processes tries to listen
the same 11111 port at the same time, but I couldn't find how to specify
different ports depending on -np parameter for mpirun. Any help or advice is
