Save movie with 3-slice template hits a wall #3802

Open markcmiller86 opened 5 years ago

markcmiller86 commented 5 years ago

Describe the bug

90% way through creation of a movie, performance bogs down to a crawl. It is chuging along at about 1 frame/sec save rate and then at the end, it takes forever for each frame to render.

To Reproduce

  1. Open wave_smaller.visit (see below).
  2. Put up PC plot of pressure
  3. Save movie...
  4. select existing template, 3-slide
  5. Select scalar field 'pressure'
  6. Hit continue, continue, continue...until you start generating the movie.
  7. Watch it chug along at fairly fast rate.
  8. When getting mid-way through slices for last timestep, it falls off a cliff in performance

I don't think the specific file matters but here is what I was using...

This is happening on 3.0.1. I have observed on OSX. I haven't tried any other OS.

I check performance monitor and don't see any memory, cpu or networking oddities.

This is even worse for other datasets. I'm trying to generate a simple shock tube movie, and, around frame 150, my entire laptop freezes and needs to be restarted. I have two plots—one pseudocolor and one filled boundary—and a single transform operator.

@aowen87 did you watch with Activity Monitor to see if you noticed anything unusual there?

aowen87 commented 4 years ago

Unfortunately, no. I would have started to had I still been able to control my mouse. I can try repeating this again with the monitor up, but I'd prefer to wait until the end of the day so that I don't lose all of my sessions again.

Okay, I just ran it again but only saved 50 frames. About halfway through, VisIt's viewer becomes unresponsive. It did complete, though. Screen Shot 2020-04-08 at 10 52 00 AM

Any memory/stack issues?

Memory looks similar. This was after saving ~70 images. Screen Shot 2020-04-09 at 8 20 03 AM
