Sunflower A.12.02.L

Description

Peach is falling
When Frank lands on the branch his weight causes the peach to fall towards the ground - in slow motion.

This scene is quite hard to render without a camera that supports moving focus. We're going to try out a technique that allows us to move the focus slightly as a postprocessing effect.


This is the left eye view of the stereo video. The right eye is rendered in Session 1458.

The processing time per WU increased a lot for this session over time: The first ones were done in 10 - 20 minutes, the last ones (397 and 399) took 10 - 12 hours for me which of course caused some deadline issues.

Seems like the WUs get done in the end anyway though, so I guess it doesn't really matter by now, since the session is already nearly done.

Nice, still having a WU from this session although it's already finished. :-\
It crossed the 51 hours mark now. Wonder if it ever ends, but the task manager still says cpu usage is at 100%, so it can't be stuck I assume...

The peach falls from the branch and as it approaches the camera the background is progressively blurred out more and more. It's this blur that is causing the rendertime to go up a lot.

The deadlines for the right-eye session that is matching this one has been increased a bit.

Damn, came home and saw that my WU was gone, but after I looked into my account I saw that it ended with an error. Over 60 hours for nothing... :-(
Now what happened here? Nothing special to see in the log file, except for exit code -10, what is that?

That is the progress monitor being angry - and rightfully so, the last 3 workunits were taking a crazy long time! I'll have to look into that.

Hm... since I'm not much into BOINC coding unfortunately, what does that specifically mean?
Speaking of progress - I know that it freezed at 97,*** for over 40 hours - has that something to do with it?

It's not a BOINC thing. It is Glue3 (the glue between Blender and BOINC which is provided by BURP). Glue3 contains the code that launches, monitors and controls the rendering engine (Blender) on your machine. It has a safety feature that kills workunits where the progress is stalled for a long time to avoid having clients enter an infinite loop. So you are exactly right, the fact that it froze at 97% was what eventually killed it.

If you take a look at the output of your workunit you can see Glue3 writing out (at the bottom):
---------------------------
Exception caught: ProgressMonitor kills
Status: -10
---------------------------


When Glue does anything it will always write the reason between two lines at the bottom like that.

Thanks for the explanation, Janus. Gives me a better view now. :-)
