% Unstalled execution (higher is
better)
Percentage of unstalled cycles with respect to
total number of elapsed CPU operating cycles.
% of Cycles lost due to front end
stalls (lower is better)

dependency stalls. It excludes FR/FR dependency
stalls.

% of Cycles lost due to GR/GR
dependency stalls

% of Cycles lost due to FPU
(floating-point unit) stalls
Percentage of cycles lost due to floating-point
unit stalls.
% Core cycles due to this thread 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.
