traps Metrics Summed for Entire Run
This section describes the metrics summed over the entire run of your application under HP Caliper.
BACK_END_BUBBLE.FE | Full pipe bubbles in main pipe due to front end. This is the |

Full pipe bubbles in main pipe due to execution unit stalls. This is the number of cycles lost (stall cycles) due to stalls caused by the execution unit.
Full Pipe Bubbles in Main Pipe due to FR/FR or FR/load dependency stalls. This is the number of cycles lost (stall cycles) due to FR/FR or FR/load dependency.
Full pipe bubbles in main pipe due to general register/general register or general register/load dependency stalls. This is the number of cycles lost (stall cycles) due to general register/general register or general register/load dependency.
Full Pipe Bubbles in Main Pipe due to GR/GR dependency stalls. This is the number of cycles lost (stall cycles) due to GR/GR dependency stalls.
Full Pipe Bubbles in Main Pipe due to pipeline flushes. This is the number of cycles lost (stall cycles) due to branch misprediction or exception/interruption flush.
Full Pipe Bubbles in Main Pipe due to L1D cache. This is the number of cycles lost (stall cycles) due to L1D cache and L1/L2 DTLB.
Full Pipe Bubbles in Main Pipe due to RSE stalls. Percentage of cycles lost due to stalls in RSE spilling/filling registers to/from memory.
Number of elapsed CPU operating cycles. (Note: This event is called CPU_CYCLES on Itanium 2 systems.)
When HyperThreading is on, this is the number of elapsed CPU operating cycles used by only this process's hyperthread.
Number of elapsed CPU operating cycles used by both hyperthreads. Available only when HyperThreading is on.
Percentage of unstalled cycles with respect to total number of elapsed CPU operating cycles.
Percentage of cycles lost due to instruction cache, ITLB, and branch execution stalls.
Percentage of cycles lost due to branch misprediction or interruption flush.
Percentage of stall cycles lost due to DCACHE and DTLB stalls.
Percentage of cycles lost due to stalls in RSE spilling/filling registers to/from memory.
Percentage of stall cycles lost due to FPU and register dependency stalls. It excludes FR/FR dependency stalls.
