Need a more granular way to define capacity?

With each render, there is a different limiting factor. Sometimes it uses a lot of CPU, RAM, or VRAM, or the files are very large so network I/O is the limiting factor. With a single value defining what a render node is capable of, it is difficult for artists to determine what their render is going to need in terms of capacity. Some After Effects renders can be run with 2 or 3 instances per machine, while other renders require 100% of a given system resource. We have seen little to no impact running a CPU-intensive task locally (like a simulation) while CGRU renders a GPU-intensive task at the same time on the same machine. But with "capacity" defined as a single number, we cannot tell CGRU that this is ok, as it has no way of knowing that one task uses 100% GPU and the other 100% CPU, so there's nothing preventing 2 GPU-intensive tasks on the same node, which would cause a slowdown at best but more likely will freeze the machine.
It seems like CGRU needs a better way of understanding a render node's real capacity, perhaps a CPU, GPU, and RAM capacity?
