Detailed Description

This class represents the number of cycles per resource (fractions of cycles).

That quantity is managed here as a ratio, and accessed via the double cast-operator below. The two quantities, number of cycles and number of resources, are kept separate. This is used by the ResourcePressureView to calculate the average resource cycles per instruction/iteration.
