Thanks a lot.
Actually, I tried now to start the pvserver with mpirun -np 4 -mca
mpi_yield_when_idle 1 pvserver , but I did not observe any differences to
mpirun -np 4 -mca mpi_yield_when_idle 0 pvserver in the CPU-usage.

Re: [Paraview] ParaView parallel - CPU-exhaustion
Natalie,
An explanation about the continual use of CPUs can be found on this wiki page:
http://www.paraview.org/Wiki/Setting_up_a_ParaView_Server#Server_processes_always_have_100.25_CPU_usage
The licensing of ParaView is fully open, so there should be no problem
installing on the VSC.
File format for large scale parallel file access is a sticky issue right now.
Parallel file formats are still evolving. The HDF5 library included with the
ParaView build is used for the XDMF reader and, yes, it is designed to do
coordinated parallel reads. As such, it is probably a good first choice for
files read on a large computer.

Hi!
I have recently noticed, that when starting the pvserver in parallel mode, it
uses the full capacity of all CPU's it's started at, regardless if there is
actually something visualized or not. Is there any option to prevent this?
Apart from there is the idea to install ParaView at the new supercomputer in
Vienna, the VSC (Vienna Scientific Cluster). Since it is open source, I
suppose, there are no judicial problems, but please correct me if I am wrong.
So I wanted to ask about parallel reading of files and so on - ParaView does
that for sure, but honestly, I don't really know which fileformat this
requires. HDF5 can be read correctly, I think, since there is a compiler
option, but other file formats - it would be nice if you could point me
somewhere to read about "ParaView on supercomputers".
Thanks a lot!
Kind regards,
Natalie Happenhofer
