On the "Configure session" page, under the "Priority" tab, it says :

Cost: Up to Boost*Parts*Frames credits


I don't understand this phrase at all.

My question is : Does boosting burn the credits I earn ?
And how much ?

At the moment (for the past 10.5 years) everything gets boosted for free because the farm is so big compared to the amount of stuff rendering.

The idea is that if we ever hit a situation where there is constantly too much to render it will start costing credit to have your stuff rendered before everyone else's. You earn credit by contributing to the farm, so people who contribute a lot get to render faster than other people. Rendering during "silent" periods where there isn't much to render would still be free.
On the priority page you would select how much you would be willing to spend on having that session rendered - with the lowest option being the slowest one.

But as said, for now, the problem is rather to find something hard enough to render to actually fill the 3 farm segments (Linux, Windows and GPU) entirely.
To do that you would need at least 3 simultaneous sessions with
1) Lots of frames
2) Lots of time per frame and
3) Each frame should support splitframe rendering - i.e. no post-pro nodes on-farm in the session.
4) Low memory usage
The combined rendering power in this situation is absolutely mindblowingly insane - Which is why it doesn't happen very often.

So this is one of those very few cases on the Internet where the "Up to" part actually means zero (for now).

Interesting. I've got another question now :

3 farm segments (Linux, Windows and GPU)


Don't Windows and Linux machines request and render the same jobs ? Why do you separate them in different segments ?
I understand how GPU ≠ CPU but not how Windows ≠ Linux on this.

They have historically produced ever so slightly different results and have had to be split into two different categories.

But what makes an uploaded project a Linux or Windows project ? Is it the version of Blender ?
And by "slightly different", do you mean different in render time or different in color results ?

It is assigned pretty much randomly. Colour.

Strange because it doesn't seem to be assigned randomly. The only project I uploaded from linux is also the only one that got assigned to linux on BURP. That would be quite against the odds.

So if someone doesn't know that the credits priority is not being used at the moment and chooses the Boost X2 option, will his credits still be taken or will the program ignore that option ?

It is somewhat but not entirely ignored. No credit is deducted.
