Activity colouring depending on HEC usage

[varosi]

Intel VTune have similar profiling information which is helping to find places where not all available cores (HECs) are used.
The idea is to use tri-color/semaphore (red, yellow, green) to paint the activity diagram depending on HEC usage. For example, if activity is less than 50% it's red, less than 75% yellow and more - green. So programs are pushed toward more parallel computations.

Actual HEC activity could be painted, too.

I don't remember if it's enabled by default, but doesn't the graph where the height of stuff depends on how many HECs are used suffice?

Yes, it is, but not obvious enough in my opinion. It'll guide more into the best direction.

btw, other way of representing this is to paint the background only in three colors.
