Janus, can you look at this WU http://burp.boinc.dk/result.php?resultid=114516 ...

I spent over 11 hours processing it and it completed @ 100%, this is BS as far as I\'m concerned. 2 other people got over 200 Credits for it and the amount of time I took was within the range that they took.

I seen this WU before it started and it showed it had been sent out 16 times already. I almost aborted it before it started but let it run anyway. Rest assured when I see a WU like this again it will go in the garbage with rest of the junk WU\'s ...

This is clearly a bug - and if you have a look at the max # of error/total/success results (10, 20, 10) you will also see that this has been changed for future workunits in order to attempt to avoid similar situations.

I\'m sorry, but things like this happen when testing stuff - you need to be aware of an issue before you can correct it.

Janus, The wu\'s I was crunching with this host were taking about 24 hours or more to complete (79,451.43 secs). I finished one on it and started the second, but by the time that I\'d noticed that the second one was at (est.)17:45:03 and with 17 more hours to complete, the deadline for that wu and the remaining 4 or 5 wu\'s had been reached.

I aborted the one that was in progress, and the rest of the ones on that host.

The above host has 1GB RAM and is a AMD XP 2000.

I had no issues with my other host which is a AMD64 3500...

WU 16109
WU 16113

It\'s amazing how complex a render can become even using just simple effects such as reflection. The frame you had is particularly difficult to render because there\'s 3 semi-transparent reflecting objects behind each other and all inside the frame. This causes the maximum amount of computation to be needed since the light will bounce between the objects many many times before reaching the camera.

Just thinking out loud here but would this be rendered much faster by a GPU from a high end video card?

There\'s not yet any general purpose GPU computation libraries available. The answer would probably be yes though.
If you are interested in general purpose processing on graphical processing units (like on a 3D accellerator) you can get more information about how far this field is progressing at GPGPU. Just a slight warning: this is still very much a research area, so things may be a bit difficult to understand if you don\'t know the terms being discussed there. It will be at least a couple of years before any ordinary computation application will easily be able to make extensive use of the GPU for processing.

@Misfit: Hm, I thought the renderer of Blender would be a raytracer? You won\'t get as high quality results by rendering as by using a raytracer. Besides, every GPU renders different. The chance is high to mess up all rendering if you use different cards even by the same manufacturer.

However it\'s possible to perform calculations on a GPU (as the GPGPU project does). But as Janus said, this is still very experimental.

Hi there!

Is it possible that i crunched a WU to 50% and the wu \"jumpes back\" to 20%?
The first WU needs nearly 7 minutes and i stoped the second at 6hours!!

With the current version of BLENDER, and until Janus has time to convert the newer version of BLENDER to BURP/BOINC, when the submiter of the animation uses motion blur, the % will go up and down until the end.

thank you!

...just for a few minutes the wu jumps from 95% back to 6% *grrr*
I\'ll wait...

I am getting the same thing. I have been crunching on one unit for 37 hours now.

What is in this thing?

OK, it finnaly finished
147000 14954 8 Jun 2006 12:09:15 UTC 10 Jun 2006 10:45:33 UTC Over Client error Computing 158,565.08 284.11 ---

158,565.08 seconds of work= 2642.7513 minutes = 44.04585 Hours = 1.8352 days of processing.

Will i get any credit for this? 2 others had client errors and one is a no reply. Janus, I undrstand that this is an alpha project and you needed to test things out under a full load but 1.8 days of straight processing woth out any credit is annoying.

I have WUs is the same state. If everyone else error\'s out so that there is no comparison between the two results, do we still get credit?

Please read/comment here as well:

Should session 192 be restarted with smaller frame pieces?
