be obtained from lower level caches or memory, leading to extra cycles.

This is the number of cycles lost in replay in the DET stage. This is the number of cycles lost in replay in the EXE stage. This is the number of cycles lost in replay in the WB2 stage.

Percentage of unstalled cycles with respect to total number of elapsed CPU operating cycles.

The percentage of cycles lost due to flushes in the WB2 stage with respect to the the total number of elapsed CPU operating cycles.

The percentage of cycles lost due to stalls in IBD stage with respect to total number of elapsed CPU operating cycles.

The percentage of cycles lost due to replays in DET stage with respect to total number of elapsed CPU operating cycles.

The percentage of cycles lost due to replays in EXE stage with respect to total number of elapsed CPU operating cycles.

The percentage of cycles lost due to replays in WB2 stage with respect to total number of elapsed CPU operating cycles.

Percentage of cycles lost due to GR load dependency stalls (stalls in IBD, RAW and WAW hazards in EXE and DET replays) with respect to total number of elapsed CPU operating cycles.

The total number of instructions retired without considering the nop's and instructions with predicate disabled.

The cycles per instruction, including nop and predicated off instructions.

The instructions per cycle, including nop and predicated off instructions.

The cycles per effective instruction, excluding nop and predicated off instructions.

The effective instructions per cycle, excluding nop and predicated off instructions.

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.
