Re: [Paraview] Tiled Display

2016-10-17 Thread Mathieu Westphal 
Hello

pvserver is an MPI application ( considering it was compiled with it, which
is the case for default binaries )
You should document yourself on the ways to run mpi program on mutliple
computer with the mpi implementation you are using

With openmpi it would be something like that
mpirun -machinefile path/to/your/machine/file -np 4 ./pvserver

you machine file should like this :

//machinefile:
hostnameA
hostnameB

and each machine must be accessible via ssh.

Once again, it is nothing specific to ParaView, but to MPI.

Regards,



Mathieu Westphal

Re: [Paraview] Tiled display

2009-10-22 Thread Greg Abram 
No, I mean the whole display.  I was just wondering since (I think) cards don't 
generally support 8K windows, and naively, a simple sort-last algorithm uses 
full-size targets for rendering.  We have a 15x5 tiled display, and I'm 
thinking about running to the whole thing.

If not, I'd be very interested to know how your setup differs from mine,
as it seems that that bug basically makes Paraview's current TPD support
unusable.

Hi Jean,

I know of at least one change to the tile gap code, and that was this bugfix-

But this shouldn't be causing the problem.  I'll test to make sure and

 ParaView 3.4 and EqualizerGraphics 0.9 work perfectly well on the same
 cluster and tiled display setup, with no gaps between rows and columns.

 Has some setting gotten lost in version 3.6 and above?

Unfortunately, stereo rendering is not supported with tile-displays.

2009/5/19 Andrés Felipe Padilla anfe...@gmail.com

 Hello all,

 I'm working with paraview and a tiled display. We have configured the tiled
 display visualization using -tdx and -tdy without problems, but we are
 wondering how to configure our tiled display with stereo support. We have
 read that you change some lines in the ParaView code in order to support
 stereo, and then run paraview with the --stereo option, but we have not
 found such an option in pvserver. Is there any way to configure the pvserver
 with tiled display and stereo support? Thanks a lot in advance for your
 help.

Re: [Paraview] Tiled display with multi-gpu.

2009-04-20 Thread Utkarsh Ayachit 
Yes, just run pvserver as follows:

mpirun -np 2 pvserver -tdx=2

Of course, you'll have to build your own MPI enabled ParaView (you
cannot use the binaries provided by on www.paraview.org). You'll have
to ensure that the environment is set up correctly so that each
pvserver processes gets the right display etc.

Re: [Paraview] Tiled display with multi-gpu.

2009-04-20 Thread Moreland, Kenneth 
That's basically what Utkarsh meant by needing to set up the environment 
correctly.  Typically the GPU used is determined by the DISPLAY environment 
variable.  :0 is typically the first GPU and :1 is typically the second 
GPU.  You need to launch pvserver such that node 0 gets :0 for the DISPLAY env 
variable (or -display flag) and node 1 gets :1.

I Think I did what you are asking  some time ago and used a pvx file 
which I handed the pvserver  as a command line option,
I can't recall all the details but here is one of the files, it was 
used when launching 2 pvservers via mpi on the same machine with 2 
graphics cards.   :


$cat myconfig.pvx
?xml version=1.0 ?
pvx
  Process Type=client
  /Process
  Process Type=server
Machine Name=hostname1
