HP UX Caliper Software manual Cycles Metrics Summed for Entire Run

The report shows measured data by thread, load module, function, source statement, and instruction bundle.

Command-line options allow you to control the amount of data reported, how the data is sorted, and the number of statements and instructions reported for each sampled program location.

Example Command Line for Text Report

$ caliper cycles -ra -o reports/sample.txt ./wordplay thequickbrownfox

Example Command Line for CSV Report

$ caliper cycles --csv csvout ./wordplay thequickbrownfox

cycles 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
	number of cycles lost (stall cycles) due to instruction cache,
	ITLB, and branch execution stalls.
BE_EXE_BUBBLE.ALL	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.
BE_EXE_BUBBLE.FRALL	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.
BE_EXE_BUBBLE.GRALL	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.
BE_EXE_BUBBLE.GRGR	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.
BE_FLUSH_BUBBLE.ALL	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.
BE_L1D_FPU_BUBBLE.L1D	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.
BE_RSE_BUBBLE.ALL	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.
CPU_CPL_CHANGES.ALL	Number of Privilege Level Changes to/from all privileges.
CPU_OP_CYCLES.ALL	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.
CPU_OP_CYCLES.ALL:all_threads=true	Number of elapsed CPU operating cycles used by both
	hyperthreads. Available only when HyperThreading is on.
% Unstalled execution (higher is	Percentage of unstalled cycles with respect to total number
better)	of elapsed CPU operating cycles.
% of Cycles lost due to front end	Percentage of cycles lost due to I-cache, ITLB, and branch
stalls (lower is better)	execution stalls.
