HP UX Caliper Software Fprof Metrics Summed for Entire Run, Number of elapsed processor cycles

The report contains two levels of information:

•Exact counts of CPU metrics summed across the entire run of an application

•Sampled IPs that are associated with particular locations in the application

The default for the fprof measurement is to take a sample every 500,000 +/- 25,000 CPU cycles. (CPU_CYCLES is the event.)

You use the -s(--sampling-spec) option to change both the event being sampled and the interval. For example, if you want to keep the same variation and sample event and simply change the interval, you can use the following option: -s 100000. The sampling rate, variation, and event used are listed in the Sampling Specification part of the report.

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 fprof -o reports/sample.txt ./wordplay thequickbrownfox

Example Command Line for CSV Report

$ caliper fprof --csv csvout ./wordplay thequickbrownfox

fprof Metrics Summed for Entire Run

This section describes the metrics summed over the entire run of your application under HP Caliper.

Metrics for Integrity Servers Itanium 2 Systems

CPU_CYCLES	Number of elapsed processor cycles.
BACK_END_BUBBLE.ALL	Full pipe bubbles in main pipe.
BE_EXE_BUBBLE.GRALL	Full pipe bubbles in main pipe due to execution unit stalls.
% of Cycles Lost Due to Stalls	Percentage of cycles lost due to stalls.
% of Cycles Stalled Due to GR/GR	Percentage of cycles stalled due to general register/general
or GR/Load Dependency	register or general register/load dependency.

Metrics for Integrity Servers Dual-Core Itanium 2 and Itanium 9300 Quad-Core Processor Systems

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.
