Re: [Paraview] pvpython vtkMPIController usage? rank is always 0

[Ephraim Obermaier]

Thank you, "mpirun -n 2 pvbatch --mpi --symmetric test.py" runs as expected.

But I am now using pure python with properly set library paths. It's a bit
annoying that these pvbatch traps aren't documented in the vtkMPIController
class reference or in
http://www.paraview.org/ParaView3/Doc/Nightly/www/py-doc/. What other
surprises are to be expected when I use pvbatch??

Thank you!
Ephraim

 Hello,
 I am trying to use VTK's MPI communication from pvpython, running with
 OpenMPI's mpirun. It seems like ParaView hasn't enabled the MPI
 capabilities for VTK, although it was compiled from source with
 PARAVIEW_USE_MPI=ON and correctly found the system OpenMPI-2.0.0 libraries
 and includes.

 I am running the short example below with the command "mpirun -n 2
 pvpython test.py". The full output is also attached.
 In short, both MPI processes report rank=0 and size=1 and their
 controller is a vtkDummyController although I expected rank=0..1, size=2
 and a vtkMPIController.

 Is it possible to determine the problem with the given information? Do
 I need extra CMake settings besides "PARAVIEW_USE_MPI=ON" to enable MPI for
 VTK?
 ParaView by itself runs fine in parallel, and I can start several
 parallel pvservers using "mpirun -n 16 pvserver".

 --- test.py: ---
 import vtk

 c = vtk.vtkMultiProcessController.GetGlobalController()

 print "comm:",type(c)
 rank = c.GetLocalProcessId()
 print "rank:",rank
 size = c.GetNumberOfProcesses()
 print "size:",size

 if rank == 0:
 ssource = vtk.vtkSphereSource()
 ssource.Update()
 print " 0 sending."
 c.Send(ssource.GetOutput(), 1, 1234)
 else:
 sphere = vtk.vtkPolyData()
 print " 1 receiving."
 c.Receive(sphere, 0, 1234)
 print sphere

[Paraview] Updating Properties Panel

[Dean, Kevin]

Hey Guys,

I was wondering if there's an example for me to look at for updating values
in the fields of the properties panel. I am writing a Plugin that has the
option of reading in values from a CSV, but I would like to have the values
update in the properties panel... similar to how if you use a probe
location filter, it adjusts (x, y, z) interactivley. Thanks for the help.

Kevin

[Paraview] ParaView 5.4.0 Release Candidate 2 binaries are available for download

[Cory Quammen]

On behalf of the ParaView development community, I am pleased to
announce that binaries and source code for ParaView 5.4.0-RC2 are
available to download from

http://www.paraview.org/download/

There was a slight problem building the Linux binary and the
AcuSolveReaderPlugin, so those are not yet available, but they will be
uploaded as soon as possible. I will reply to this email when they are
available for download.

Please let us know if you run into any problems with this release candidate.

Thank you,
Cory

Re: [Paraview] pvpython vtkMPIController usage? rank is always 0

[David E DeMarle]

Run with --symmetric.

Without it, only root node reads the script and it tells the rest of the
nodes what to do via paraview's proxy mechanisms (which take effect only
for vtkSMProxy and subclasses).
With it, every node reads and executes the script and all nodes do their
own parts behind the proxies.

Re: [Paraview] pvpython vtkMPIController usage? rank is always 0

[Ephraim Obermaier]

Thank you all for suggesting "pvbatch --mpi".
At least, this returns size=2 processes, but the updated test.py (below)
hangs with the following output:

$ mpirun -n 2 pvbatch --mpi test.py
comm: 
rank: 0
size: 2
Process 0

Why is "Process 1" not printed, and why does the program hang instead of
finishing?
The file test.py was simplified to:

import vtk
c = vtk.vtkMultiProcessController.GetGlobalController()
print "comm:",type(c)
rank = c.GetLocalProcessId()
print "rank:",rank
size = c.GetNumberOfProcesses()
print "size:",size
if rank == 0:
  print "Process 0"
else:
  print "Process 1"
c.Finalize()

Thank you!
Ephraim

[Andy Bauer]

Note that you can run both the ParaView GUI and  pvpython with MPI in order
to initialize, finalize and use MPI functions but as Dave said, they
should/will always be run with a single MPI process. The argument to run
MPI with either is "--mpi".

Re: [Paraview] pvpython vtkMPIController usage? rank is always 0

[David E DeMarle]

Try your script within pvbatch.

pvpython is analogous to the Qt client application, it (usually) is not
part of an MPI execution environment. Either one can connect to an MPI
parallel pvserver.
pvbatch is a python interface that is meant to be run on the server. It is
directly connected to the pvserver.

[Paraview] pvpython vtkMPIController usage? rank is always 0

[Ephraim Obermaier]

Hello,
I am trying to use VTK's MPI communication from pvpython, running with
OpenMPI's mpirun. It seems like ParaView hasn't enabled the MPI
capabilities for VTK, although it was compiled from source with
PARAVIEW_USE_MPI=ON and correctly found the system OpenMPI-2.0.0 libraries
and includes.

I am running the short example below with the command "mpirun -n 2 pvpython
test.py". The full output is also attached.
In short, both MPI processes report rank=0 and size=1 and their controller
is a vtkDummyController although I expected rank=0..1, size=2 and a
vtkMPIController.

Is it possible to determine the problem with the given information? Do I
need extra CMake settings besides "PARAVIEW_USE_MPI=ON" to enable MPI for
VTK?
ParaView by itself runs fine in parallel, and I can start several parallel
pvservers using "mpirun -n 16 pvserver".

--- test.py: ---
import vtk

c = vtk.vtkMultiProcessController.GetGlobalController()

print "comm:",type(c)
rank = c.GetLocalProcessId()
print "rank:",rank
size = c.GetNumberOfProcesses()
print "size:",size

if rank == 0:
ssource = vtk.vtkSphereSource()
ssource.Update()
print " 0 sending."
c.Send(ssource.GetOutput(), 1, 1234)
else:
sphere = vtk.vtkPolyData()
print " 1 receiving."
c.Receive(sphere, 0, 1234)
print sphere

--- Test run: ---
$ mpirun -n 2 pvpython test.py
comm: 
rank: 0
size: 1
 0 sending.

Re: [Paraview] gpu_shader4 extension is not supported

[Burlen Loring]

that's the point. this allows you to run without the windowing system or 
GPU on the cluster. Most cluster have neither. If you wanted to provide 
the GUI then I would suggest you have two installs of both ParaView and 
Mesa. One based on OSMesa, the other based on some X11 enabled OpenGL. 
Alternatively you could install only the OSMesa capable pvserver as 
suggested in previous email and direct your users to the ParaView GUI 
enabled binaries that Kitware provides on their web site. The latter is 
what I have been doing.


As an aside, it gets messy when you have two libGL in the same build. 
One need to be very careful about library dependencies. It is possible 
to do this if one is very careful during link time. However as far as I 
know this has not been supported for quite a long time in VTK/ParaView, 
and I think it would require some reorganization of VTK OpernGL classes.

Hi Burlen,

this Mesa setup does not provide libGL requested to build paraview

It is OK for the cluster nodes but not for the frontend where I need 
this GUI even with no GPU installed.

Re: [Paraview] netcdf

[Rupert Gladstone]

Thanks very much Ken and others.

I just tested the warp by scalar filter (I didn't know about this before)
and it looks like it can do what I need with the vertical coord, like you
suggested.

What I will do is this:
I will modify the netcdf file to add a 1D x and y coord variable with the
same name as the x and y dimensions.  I will add a 3D coord var for z.  If
the Paraview netcdf interface can read this in then great!  If the Paraview
netcdf interface cannot handle the 3D z coord then I will use the warp by
scalar filter to apply the z coord var, and will also let you know in case
you want to modify the functionality.

BTW I found this info about coordinate vars on more than 1 dimension:
http://cfconventions.org/cf-conventions/v1.6.0/cf-conventions.html#_two_dimensional_latitude_longitude_coordinate_variables
I'll try the coordinates attribute as suggested in the link above, and will
send you an example netcdf file that I believe to be consistent with CF if
it doesn't work in Paraview.

Regards,
Rupert Gladstone

Interesting, I hadn't heard of this problem. I don't have an intel
card that reproduces this, but if the new version has the same issue
with FXAA and I can find hardware to debug it I'll be happy to take a
look.

Re: [Paraview] Cmake flags

[Cory Quammen]

Rustem,

You can find some of the options described at

http://www.paraview.org/Wiki/ParaView:Build_And_Install#ParaView_Settings

For others, each build flag has a brief description in the
CMakeLists.txt file, e.g.,

option(PARAVIEW_BUILD_QT_GUI "Enable ParaView Qt-based client" ON)

The description will appear in a CMake UI (ccmake, cmake-gui) if you
use that for configuration.

HTH,

Re: [Paraview] netcdf

[Moreland, Kenneth]

Rupert,

It has been multiple years since I really took a look at the CF convention, so 
I don’t remember the details of whether it supports varying coordinates across 
multiple dimensions or whether the ParaView reader supports that. If the 
ParaView reader is missing some corner of the CF convention, let us know and we 
can work on that.

In any case, you can displace a 2D or 3D image by a height value that is stored 
in a field by simply running the “Warp by Scalar” filter.

Hi all, thanks very much for your replies so far.  I must say I am finding the 
Paraview community very helpful.
Having considered my data further, I would be able to make a 1D coordinate 
variable for my x and y dimensions but not for my z dimension.  The ocean model 
uses a hybrid coordinate which can be transformed into depth, but the resulting 
depth coordinate will be spatially varying across my data set.  In other words 
my z coordinate variable will need to be a 3D variable.  From my understanding 
of COARDS and CF this is allowed.  But I think from your email that Paraview 
will not be able to associate this 3D z coordinate variable to another variable 
(e.g. ocean temperature) for the purposes of plotting.  At least, not using the 
Paraview CF interface.  Is that correct?
I don't currently have a handy netcdf file (I have a rather large one).  I 
could generate a smaller netcdf file to demonstrate the issue, but I am not 
sure it is needed here, as the problem is not that Paraview fails to read the 
file as expected, but rather than I am trying to clarify what I can reasonably 
expect from Paraview with its current functionality.
Do you have a suggestion for how to read in a (topologically) structured data 
set on a rectangular cartesian projection in which the the vertical coordinate 
variable varies across all three dimensions?  Should I ask Paraview to read it 
in as unstructured data?  I think I saw that Paraview offers some kind of 
interface for unstructured data in netcdf files.  Are the requirements of this 
documented somewhere?  Or do you still feel that I need to provide an example

Thanks again for your help.

As Aashish said, it might be easier to diagnose the issue if you sent us a

spacing of 1. This is not likely to conform with the coordinates you want.

The official documentation for the CF convention is maintained here: 
http://cfconventions.org/. In summary, you specify coordinates by using arrays 
of the same name as the dimension. So for example if you have a 3D array with 
dimensions named “Z”, “Y”, and “X”, then you also make a 1D variable named “X” 
on the “X” dimension that has the x coordinate for each grid point in the

I have seen the same thing on my PC with an NVIDIA card and Intel
integrated GPU. Obviously, FXAA isn't working with some Intel
integrated GPUs. I, too, had to specifically enable my NVIDIA card.
But that's what ParaView should ideally be using anyway.

ParaView 5.4.0 RC-2 has some improvements to ParaView's Qt widget for
rendering that *may* improve the situation. That should be out later
today (US east coast time) or tomorrow.

Ah, I haven't seen that option. Thanks for pointing it out.

Re: [Paraview] multiple visualization pipeline at a time with co-processing

[Andy Bauer]

Hi Ufuk,

If you create a vtkCPythonScriptPipeline, when you initialize it with the
script file name (which has to be done on each process) everything will be
taken care of with respect to broadcasting the file contents from process 0
to the others. We aren't sophisticated enough to parse the Python script to
see if it imports other scripts that are not part of ParaView (e.g.
paraview.simple) or Python (e.g. sys). That is why I recommended the first
approach as opposed to the second approach above. Depending on the compute
platform and how many MPI processes are in the run the difference may be
negligible but having 100K processes or more trying to access the same file
can seriously slow down an HPC machine.

Cheers,
Andy

Re: [Paraview] Integration points visualization

[David E DeMarle]

Please reply all to keep the mailing list on the discussion so all can
participate in and benefit from the discussion.

Question 1: Why delete columns? All of the columns can be point aligned
attributes.
Question 2: Are you sure you want a Structured Grid?

Table To Points will give you a simple point cloud. Table to Structured
Grid has the extra requirement that the points in the text file are ordered
regularly to make up a toplogical grid. If that is the case, then in
addition to designating the X, Y and Z columns, you also have to specify
the whole extent so that the filter knows how many cells there are in the
i, j and k dimensions.

Thanks Andy. That is exactly what i am looking for. The broadcasting

Hi Ufuk,

Unless I'm not understanding your question correctly, I think you can 
get what you want by adding in multiple vtkCPPythonScriptPipelines to 
your vtkCPProcessor object in your adaptor. Alternatively if you want 
to have a single, master Catalyst script handling other Catalyst 
scripts you can do something like the following:


import script_a
import script_b
import script_c

def RequestDataDescription(datadescription):
  script_a.RequestDataDescription(datadescription)
  script_b.RequestDataDescription(datadescription)

  script_b.DoCoProcessing(datadescription)
  script_c.DoCoProcessing(datadescription)

The first way is the recommended way though as that should be more 
efficient by having process 0 read the scripts and broadcasting the 
script contents to the other  processes for use. The second method 
will only do that for the master script.


Please let me know if this doesn't answer your question.

[Paraview] multiple visualization pipeline at a time with co-processing

I just wonder that is it possible to trigger multiple visualization 
pipeline in the same time with co-processing. The co-processing script

Re: [Paraview] gpu_shader4 extension is not supported

[Patrick Begou]

Hi Burlen,

I think there is a main concept that I do not understand in building Paraview 
and Mesa as I have also all the wiki pages printed in front of me since the 
begining. It is how to build paraview on a server without GPU _but_ with 
Paraview GUI enabled.
With the Wiki I was able to build Paraview on the workstations (with GPU and 
Paraview GUI set to ON) and on the cluster nodes (No GPU and no GUI for 
paraview). But the setup on a server without GPU and paraview GUI enabled is 
still unclear for me.


I'll try a new Mesa setup with your suggestion below but keeping 
*-DPARAVIEW_BUILD_QT_GUI=ON*


Thanks a lot for all the details you provide is this last answer.

Patrick

Hi Patrick,

Your output shows you enabled some gpu specific drivers, and GLX. I think that 
is going to screw things up for you. Best to disable all of them but the ones 
you specifically need and to explicitly disable glx.


Here is how I configured OSMesa for a Cray

../mesa-17.0.2/configure --enable-texture-float --disable-glx
--disable-dri --disable-egl --disable-gles1 --disable-gles2 --disable-gbm
--disable-driglx-direct --disable-xvmc --enable-gallium-osmesa
--with-gallium-drivers=swrast,swr
--prefix=/usr/common/software/ParaView/mesa/17.0.2/

And here is how ParaView is configured on the same system. When building 
ParaView with OSMesa the ParaView GUI should be disabled to prevent window 
system dependencies(X11, Qt etc). Note that there are a number of options in 
play to configure for OSMesa. I've highlighted them in blue below. This info 
is also on the Wiki.

Thanks for your reply.

I've attached the setup of my mesa installation. I have more options enabled 
in my config than in yours.  May be too much as this frontend has no GPU

I'll try a setup with -DVTK_USE_X=OFF as Burlen suggest, but is it possible 
to build paraview GUI with this option ? It is not clear for me.

Re: [Paraview] [Paraview-developers] ParaView 5.4.0 Release Candidate 1 binaries are available for download

[Deij-van Rijswijk, Menno]

Hi Cory,

TL;DR: I have to manually configure that the high-performance NVidia card is 
used for ParaView to get rid of problems with the FXAA option.

I notice here that the default-ON option of FXAA is giving problems. When 
enabled, there is at the beginning a smaller black rectangle in the render view 
where the axes widget should be. When a 3D geometry is loaded and Apply is 
clicked, the view becomes totally black. Disabling FXAA will show the geometry 
without having to restart ParaView.

I have a laptop with an NVidia 840M and an integrated GPU (Intel HD 5500). I 
have to manually enable the NVidia card for ParaView to get rid of this 
behaviour, so it looks like the Intel card is at fault.

Interestingly, when the NVidia card is active I can also enable/disable an FXAA 
option in the NVidia control panel. When I enable it, the screen looks totally 
wrong, as if everything (menus, buttons, etc.) is anti-aliased.

Best wishes,


Menno Deij - van Rijswijk

Re: [Paraview] netcdf

[Rupert Gladstone]

Hi all, thanks very much for your replies so far.  I must say I am finding
the Paraview community very helpful.

Having considered my data further, I would be able to make a 1D coordinate
variable for my x and y dimensions but not for my z dimension.  The ocean
model uses a hybrid coordinate which can be transformed into depth, but the
resulting depth coordinate will be spatially varying across my data set.
In other words my z coordinate variable will need to be a 3D variable.
>From my understanding of COARDS and CF this is allowed.  But I think from
your email that Paraview will not be able to associate this 3D z coordinate
variable to another variable (e.g. ocean temperature) for the purposes of
plotting.  At least, not using the Paraview CF interface.  Is that correct?

I don't currently have a handy netcdf file (I have a rather large one).  I
could generate a smaller netcdf file to demonstrate the issue, but I am not
sure it is needed here, as the problem is not that Paraview fails to read
the file as expected, but rather than I am trying to clarify what I can
reasonably expect from Paraview with its current functionality.

Do you have a suggestion for how to read in a (topologically) structured
data set on a rectangular cartesian projection in which the the vertical
coordinate variable varies across all three dimensions?  Should I ask
Paraview to read it in as unstructured data?  I think I saw that Paraview
offers some kind of interface for unstructured data in netcdf files.  Are
the requirements of this documented somewhere?  Or do you still feel that I
need to provide an example netcdf file for you to better understand the
problem?

Thanks again for your help.

Regards,
Rupert

[Paraview] How to save data for selected time range in paraview

[HongchaoWang]

Hi,

 

I am using paraview to postprocess the results from openfoam. I am doing a
3D case and thus the cell number is huge. What I want to do is to save data
from ''plot over line'' for a time frame from 23s to 28s. However, the "save
data" option seems to only either save the current time step or all time
steps. 

 

Does anyone know how to save data for selected time range or if someone
could tell me how to load data for a selected time directories? Thanks in
advance.

 

Best regards,

Wilson
