Re: [Paraview] Memory leak with Catalyst

Well... not going so well. If I run a small simulation with massif and the Release build of paraview, I don't see any growing memory in time. I also get my VTK files and images. If I run the same simulation linked against a Debug build with VTK_DEBUG_LEAKS on, there is a segfault inside one

Re: [Paraview] Memory leak with Catalyst

Thanks for the advice Burlen -- I haven't used Massif before, so this is a good opportunity to give it a try. The initialize/finalize each time approach doesn't work either. I am calling the Finalize() routine on the vtkCPProcessor class but then when it tries to initialize again, it throws:

Re: [Paraview] Memory leak with Catalyst

VTK_DEBUG_LEAKS, although will catch some serious errors, will not catch all kinds of leaks. For example you can have leaks where data erroneously accumulates with each time step, but is deleted at program termination. VTK_DEBUG_LEAKS will not catch that kind of error. It's probably better to

Re: [Paraview] Memory leak with Catalyst

Hi Andy, Thanks for the tips. I will get working on the VTK_DEBUG_LEAKS now and see what it turns up. The initialize/finalize every time is definitely a hack and not for long-term use. But, sponsors want a report on Monday and we need to be able to visualize things for that -- the

Re: [Paraview] Memory leak with Catalyst

Hi Tim, If you build Catalyst with VTK_DEBUG_LEAKS enabled it is pretty good at finding VTK objects that aren't deleted properly. You should be able to run this with a small amount of calls to Catalyst as well. If you try this and want help understanding the output (if an object like a

[Paraview] Slow with just 1M cells

Paraview is awesome for lots of functionalities, however I find it extremely slow in processing data with any filter type, or in changing timestep as soon as the model size is around one million cells or above. I have experience with a commercial tool which on the same model and pc is 100x

[Paraview] Memory leak with Catalyst

Hi, One of our users is running a very big simulation and writing out images of two slices (two different views) every 1000 iterations and writing out the data for the two slices (two different data writers) as VTK files every 5000 iterations. It is using Paraview 4.4. After 21000

Re: [Paraview] Connect ParaViewWeb to Catalyst

Hi Sven, I am not aware on any specific developer documentation for Catalyst on the ParaView side (but I haven't worked on that subject for years), although Utkarsh or Andy might know. Usually looking at the code and redoing it in the Python world is what is required, but as I said, I'm not sure

Re: [Paraview] Connect ParaViewWeb to Catalyst

Hello Seb, glad to read your answer. So the problem is not only that I was unable to find the relevant information. You say, you have not (yet) written the required code. Does "not (yet)" mean that it is on the agenda maybe within the next half year? Then I could find a workaround and look

Re: [Paraview] capability of ParaView, Catalyst in distributed computing environment ...

It may be possible to do this with Catalyst. I would guess that nearly all of the complex work would need to be done in the adaptor to integrate this properly though. On Wed, May 18, 2016 at 11:17 AM, wrote: > Yes, you are right. In this case, there will be two

Re: [Paraview] Question about the ImageResampling Filter

Hi Utkarsh, I am always building Paraview from source on Linux with all the features I need, but there is no rush, I can wait for the next release or if I badly need this functionality I will pull it from the “master”. A little background: I was actually playing around when I came across the

Re: [Paraview] Connect ParaViewWeb to Catalyst

Hi Sven, Live catalyst connection require a specific socket connection to the in-situ process with some special handling. We did not (yet) wrote the Python code to perform that specific action for ParaViewWeb so it could be triggered by the web client or configured via an argument at launch time.

Re: [Paraview] Question about the ImageResampling Filter

Lukasz, I'd suggest not to use 'ImageResampling' filter, it was a temporary fix and clearly is buggy. A new filter has been added to ParaView "master", name "Resample To Image". That would do what you want to do more reliably. What platform are you running on? I can send you links to the nightly

[Paraview] Question about the ImageResampling Filter

Hello All, Is the Image Resampling filter applicable to all datasets or only VTK Images? Each time I try to use this filter on any other dataset than a uniform image file, Paraview crashes. In Paraview Help it is written: "Accepts input of following types: vtkDataSet vtkCompositeDataSet". I am
