Percentage of cycles lost due to GR/GR dependency stalls.

Percentage of cycles lost due to floating-point unit stalls.

This indicates the percentage of available processor cycles that the measured process consumed. The other processor cycles were consumed by other process(es) running in the core's other hyperthread or were lost to HyperThreading overhead.
