Table 27 Information in icache Measurement Reports

Column	Description
% Total <metric>	Percent of the total for <metric> attributable to a given program object. The <metric> is the same
	as the <metric> HP Caliper uses for sorting, except when the sort metric is avg-latencyor
	address, in which case sampled misses is used.
Cumulat % of Total	A running sum of the percent of total for <metric> accounted for by the given program object
	and those listed above it.
Sampled Icache	Total number of sampled instruction cache misses attributed to the given program object.
Misses
Icache Latency	Number of cycles expended on instruction cache misses summed across samples for the given
Cycles	program object.
Avg. Icache Laten.	Average number of cycles expended on instruction cache misses across samples for the given
Cycles	program object.
Kernel Thread	Kernel Thread ID suffixed with the the name of the routine that the thread will execute once it is
Identification	created.
Number
Load Module	Shared library or the main executable.
Function	Routine from your application.
File	Source file associated with a function.
