Priority is a price plan you can choose to render a job. You have a choice
of Low, Medium, and High. Each priority offers you a different set of
features and has a different rate. The higher the priority, the faster the
rendering.

Per job limit is the maximum number of nodes you can use in a single
rendering job. If you have mulitple shots or scenes that you need to
render at the same time, each of them can use the number of nodes
available for given priority. For example, you can have:

- job1 - 10 nodes, job2 - 0 nodes etc. (on Low)

- job1 - 25 nodes, job2 - 25 nodes etc. (on Medium)

- job1 - 50 nodes, job2 - 50 nodes etc. (on High)

Total or user limit is the maximum number of nodes you can use in total
at one time for all jobs that are rendering. It is a limit that applies only to
projects rendering on Low priority.

Node is a computer designed and built for network rendering. You can
think of it as a specialized server.

OB hour is the basic unit of GPU cost calculation. It is a price for 1
OctaneBench (OB) used in an hour of rendering. It means, we take the OB
points of all the nodes that were used in rendering a job and add them
up. Then we multiply that total by the rate according to the given Priority.

Example
10 nodes x 587 OB (Tesla K80 node) = 5870 OB (total OB points)
5870 x 1h x 0.0025 (low priority) = $14.7 (˜$15 per 1h on 10 nodes)

Node hour is just like the OB hour but the difference is it represents the
cost for a node and the rate is usually rounded up. It is a price for 1 hour
of rendering on a single GPU node.

Here’s another example:

Let’s suppose you have 50 frames to render. Each frame renders 1h long and you choose to render them on Medium Priority.

Medium Priority = $2.25 per node hour
50 frames (50h) x $2.25 = $112.5
