Just how exactly long are these sessions? I\'ve got one running at about 3 hours and it\'s showing 1%

I may have accepted this with a too low split-frame setting. As a consequence this session will be taken out of the normal renderqueue and completed with the new background render method.

One of the interesting thoughts is whether Blender could potentially support checkpointing by allowing a \"pause\" operation that simply dumps all or a significant part of the active memory to a file upon request. Whenever Blender is restarting a render it could then be possible to feed in this memory dump as a starting point.
Looking at the fact that Blender is a bucket renderer the dumped memory could simply be all completed buckets. Upon restart it would then regenerate the octree, maps etc. and skip the completed buckets and continue from there.
Theoretically it is possible to do stuff like that and even get a quite compact dump. However, the actual implementation may prove too difficult for anyone to ever implement it. Still, a feature like that would be perfect for systems like BURP where sessions like this one really could use the checkpointing functionallity.

For now, all we can do is use hibernation to preserve the rendertime.

The goal is worth the effort.

... As a consequence this session will be taken out of the normal renderqueue and completed with the new background render method.

Are the deadlines of sent/unsent WU\'s remanaged in the new background render method or even suspended, too?

Maybe it should be restarted with a framesplit.

It has taken 12 hours to get to 15% on this WU

http://burp.boinc.dk/workunit.php?wuid=1116303

Is it worth continuing or is this session likely to be cancelled?

Thanks

The return times for this session are excessive. It has ben cancelled and will be resubmitted with a more appropriate splitfactor as Session 826. Hosts that have returned results for this session will receive credit.
The target is to stay under 3hr per WU and above 15 mins, which is clearly not the case for this session.

Please abort any running workunits unless you would like to see the total runtime just for the fun of it.

How do you make the graph? Are the points from the \"stderr.txt\" file, or is that a BOINC plugin?

In a linux shell I made a textfile
grep Progress0 slots/2/stderr.txt | sort -u -n --key=1.11 |cut  -c 20-,19,9-16 > burp818.cont.txt

to import as csv-type file in OpenOffice.
In the generated chart I had to limit the number of datapoints to about 30000 :-(

My wingman diederiks, rendering on Windows and suffering from heartbeat timeout after having done half the work in 17 hours, could get his progress so far similarily from the result page, cause stderr.txt is lost by completing rendering.

Thanks for interest.

Gnuplot is better for graphs. This is now my script.

#!/bin/sh

logfile=/path/to/BOINC/slots/1/stderr.txt

cat $logfile | grep Progress0 | sed -s \'s/Progress//g;s/\\/1//g\' > ~/burpstat

gnuplot << EOF
set terminal png
set output \"~/burplog.png\"
set xlabel \"Seconds\"
set ylabel \"Percentage\"
set title \"Burp Workunit - from `date`\"
p \"~/burpstat\" using 2:1 title \"Workunit\" with lines
EOF

display ~/burplog.png

rm ~/burpstat
rm ~/burplog.png


Save the graph is simply with \"display\".

Great script, thanks!
For convenience one may use
slot=1
logfile=/path/to/BOINC/slots/$slot/stderr.txt

to rewrite the script for dynamic use of slots.

Guess, that this promise needs some batch processing after all concerning results are in. Will come by time.

Yep, same here.
Two returned results with long render time validated with 0:

http://burp.boinc.dk/result.php?resultid=5174190
Guess the session cancellation is guilty on that. ;-)

Ok, let me correct myself then:

Hosts that have returned results for this session, finished or otherwise, will eventually get credit for their work. It may take a little while (up to a few weeks) before it is possible to start granting credit for units that did not complete normally.

So far the session has been marked for later inspection and it will stay on the status page. When it disappears from there all credit should have been granted. Until then please stay patient, there is no need to report missing credit just yet as this process, although slow, is more or less automated.

Thanks for clarification, Janus.
Although I wouldn\'t have mind about losing some hours of work, that\'s normal on some projects I participated in the early stages, so I\'m used to it. ;-)
