I know it\'s a fact of life for distributed rendering, but it may be worth mentioning that the WUs for this session are taking longer to down- and upload than they\'re taking to render...

EDIT: ...which may say more about my lousy upstream connection than anything else.

It seemed to be about 3 minutes to compute and 5 minutes to upload, the upload files are about 2mb. Probably another one of those that would have been faster locally rendered... it\'s already done handing out WU\'s, looks like it\'s just waiting for them to come back finished.

Oh, I\'m sorry guys.
I have no idea how big the blend-files are normally.
And how can I make my file smaller? Or should I make another topic about that in the message board?

Hm... something is wrong here, I\'ll have to look into it.

I see...

Delete it if you want. ;)
I will try to render it on my kick-ass Sempron tonight. :p

I\'ll give BURP another chance when I\'ve more frames.

But how do I resize the blend-file. There are some textures in it, they probably take lot of bytes...but can I resize them or something?

Usually choosing the right image format for the textures helps a lot. If they consist of few non-gradiant colours (like in cartoons) GIF or PNG is usually a good choice, if they have many gradients or lots of colours (like photos) JPEG or PNG are usually the best thing.
Once that is said, all of the formats have different settings that control how they determine whether space or image quality should be a priority. Getting a good balance can be a challenge.
Another obvious factor is the resolution of the image/texture.

The issue seemed to be with the validator here. It should be working again now and will be picking up on validating the results. I\'m sorry that your session ended up being a test-bunny like this.

Actually, the download times for this particular session aren\'t really the issue (though I do like the way the 20KB texture looks in the scene better than I like the way the 2,000KB texture does). Since the upload time exceeds the render time (and the server won\'t hand out more jobs until the uploads are finished) the system will break down even if the download time is zero. Using loki\'s rough time estimates (which seemed to correspond with what I was getting) it works out to be something like

T 0 Begin rendering WU #1 3 Finish rendering 1 & begin uploading 1 & begin rendering 2 6 Finish rendering 2 & begin rending 3 8 Finish uploading 1 & begin uploading 2 & download 5 9 Finish rendering 3 & begin rendering 4 12 Finish rendering 4 & begin rendering 5 (if it\'s DL\'d in 4 min) 13 Finish uploading 2 & begin uploading 3 & download 6 15 Finish rendering 5 & begin rendering 6 (if it\'s DL\'d in 2 min) 18 Finish uploading 3 & begin uploading 4 & download 7 & finish rendering 6 & begin rendering 7 (if it\'s DL\'d in _0_ min) ...


By the way, ThomasVI --- it\'s always a pleasure to be able to help with the rendering. I\'m not complaining about your project at all.

That\'s an interesting and very valid point - and something that hasn\'t been taken into consideration so far.
This issue increases as HD-resolution rendering becomes the norm since the upload size is more or less directly proportional to the resolution of the image being uploaded. Generally, though, as the resolution increases, so does the rendering complexity.

I guess the main thing to realize is that distributed rendering really only \"works\" if you have something complex to render.

yeah, it\'s perfectly fine animation, just not complex enough... i think we need another one to render that takes about a week or longer
