It is still doing it, I guess I will just wate till tomorrow then. ;) Of the 3 comps I have at home, only my core2duo is having problems.

Great work Janus, it\'s great to see BURP churning out results, as well as such a speedy fixing of problems.
A couple of things:
There are several sessions that have been rendered that only have two frames - is this correct?
What version of Blender is BURP currently using? I seem to remember it being updated - was that to 2.42?

Thanks, and keep up the good work!

I\'m just wondering - there are many sessions shown \"In Progress\" with different memory requirements. However, my client keeps getting the message \"Your computer has 883.14MB of memory, and a job requires 1536.00MB.\" (that would match session 271 \"Robot\"). All other sessions (at about 2 am UTC: 255, 272, 276, 278) still show something like

BOINC 25 Feb 2007 23:44:41 UTC Done
Render ETA: Unknown
End ... Session hasn\'t ended yet..

Does that mean there are no WUs generated for them yet? Or does the scheduler only check the topmost WU in its cache (simply FIFO) and ignores all other sessions (although I would match their memory requirements)?

My current client is running on Linux. I don\'t even know if we have an application for that platform now that we have reached alpha?

I keep getting that message for about two hours so if you automized creation process there could be something wrong?

Yes, although they should have had only 1, since they are still-images - there\'s an off-by-one error to hunt down somewhere.

What version of Blender is BURP currently using? I seem to remember it being updated - was that to 2.42?

Yes, 2.42a to be exact.

[...] Does that mean there are no WUs generated for them yet? Or does the scheduler only check the topmost WU in its cache (simply FIFO) and ignores all other sessions (although I would match their memory requirements)?
This night we were running FIFO, right now we are trying a random scheduling. Later this week we\'ll try random scheduling with forced continuation (ie. a client that has a particular session must finish all work on that before going to the next).

[quote]My current client is running on Linux. I don\'t even know if we have an application for that platform now that we have reached alpha?

Unfortunately, as mentioned earlier, I\'ve run a little short of time and that has had to hurt this project. I decided to cut down on the amount of time I spend on the clients, since that\'s where I\'m most ineffective. That includes the linux client.
However, there\'s soon to be an announcement with the current client code so that you can compile and/or fix it yourself for whatever system you like.

core2duos rock

Daily quota upped with a further 33% from 300 to 400 per CPU.

Thanks for uping the WU again. I still cant get work for it is still saying 300/cpu, however, last time it seemed to take a while to pick up your new settings. I will check in the morning.

Is it normal, that i don\'t get sessions anymore? There are more then 19 000 parts in the waiting queue but my BOINC will not download any sessions...

And that means?

Are there to many clients/to less servers? Or is there an other problem? Sorry, I\'m not so good in English.

€dit:

I think, It\'s a good idea to send bigger parts to the clients that the server must not have so many connections and send bigger files. A workunit with about 30 minutes to work seems good on my PC (AMD Athlon XP 2400+). At this time, the CPU\'s working time is about 3 minutes or less.

On all the other sessions over the last 2 years I have been able to have more than one Burp wu at a time but not anymore. This cause some annoying behaviour as you can see from my logs. It won\'t get more until after it has finished the one it is doing.

Good news, it finally started giving me more than 1 wu at a time. If you changed something Janus, then I thank you.

Message 4684 - Posted: 27 Feb 2007, 4:30:34 UTC - in response to Message 4599.  

snip...
Unfortunately the client-side stage of affairs isn\'t as good as I\'d have hoped for at this point, but due to time constraints this is how things are. The following issues still remain to be fully corrected:

  • Timing isn\'t entirely accurate
  • Sometimes the client leaves a Blender.exe process running out of control. This may cause the client to stall and may even interfere with other projects running on the same BOINC client.
  • No support for resuming from disk


So far the best temporary solution to the second client issue is to set your \"switch between projects\" time very high (like 20 hours) in your general preferences or avoid running BURP alongside with other projects.
The best solution for issue #3 is to use \"Suspend to memory\".

With all this in mind, Alpha here we go!



Hurrah!!! Bring on the next stage!

In my opinion the best solution to both #2 and #3 is upgrading to the latest client (5.8.16+).

There has been code checkin that should kill blender even if it does not exit smoothly on it\'s own. This has not made it into a client at this time but should be in 5.8.16 and later.

All of the 5.8.x clients try to switch only at checkpoints. So if an app does not checkpoint it will tend to keep running until finished.


Sorry gang I was wrong here. The code to kill orphaned apps will not be in a client until the 5.10.x clients.

Message 7409 - Posted: 10 Jan 2008, 19:53:53 UTC - in response to Message 4621.  

The solution was to rewrite the stitcher from scratch (again, yes) so that it uses memory and time proportional to O(size) and not O(size*parts). The new stitcher has been running smoothly for 15 mins now and processes even very large frames in just seconds.

Tiles are always vertical, aren\'t they? If you use libpng directly, I think it should be possible to stitch tiles with an O(image_width) memory usage, plus any internal libpng buffer.

And yes, I realize I\'m bumping an old thread.
