[Paraview] Extremely slow animations

[Moreland, Kenneth]

Martín,

I think we would need some more information before we could narrow down what might be the problem. It sounds like the data you have is static. That is, the tubed lines are the same for every frame of the animation. Is that the case?

In your pvserver launch, how large is the parallel job? How many nodes in your cluster are you using? How many processes per node?

What type of data file are you loading? Not all file formats will be automatically distributed across a parallel job.

It might be helpful if you took a look at the timer log (Tools -> Timer). That will give you an indication of how long things are taking.

-Ken

Subject: [EXTERNAL] [Paraview] Extremely slow animations

Dear Paraview enthusiasts, good day. I did an animation using a single data file, camera-follow path, rendering about 800 stream tracer lines, with tube filters using a mac book pro without gpu cards, and it took me about 2-3hrs. I then tried to do a similar animation, but it turned out to extremely slow, using pvserver over remote resources, through an ethernet connection, apparently with more ram memory than the mac instance, and with GPU cards . It does not make sense. According to the sys admin folks they did a parallel, gpu enabled, built of the pvserver. The slowdown seemed to be associated with the animations, i.e. the session was fast for rendering and working with the data.

Any hints will be greatly appreciated.

My best, Martín
