%Cycles lost due to stalls (lower is better)

Number of ALAT entries replaced.

Retired Number of advanced check load per 1000 instructions retired .

Number of failed advanced check load per 1000 instructions retired.

Percentage of cycles lost due to stalls.

% Core cycles due to this thread

This indicates the percentage of available processor cycles

In this table, “program object” refers to any of the following:

•Thread

•Load module

•Function

•Source statement

•Instruction

Column

Description

% Total Sampled ALAT

Percent of the total for <metric> attributable to a given program object. The <metric> is the

Misses

same as the <metric> HP Caliper uses for sorting, except when the sort metric is 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 ALAT Misses

Total number of sampled failed chk.a/ld.c instructions attributed to the given program

 

object.

 

 

Kernel Thread

Kernel Thread ID suffixed with the the name of the routine that the thread will execute once

Identification Number

it is created.

 

 

Load Module

A shared library or the main executable.

 

 

Function

Routine from your application.

 

 

File

Source file associated with a function.

 

 

Line

The column contains one of these:

Slot

• A source-code line number for rows showing statements

Col,Offset

• An instruction slot number for rows showing instructions not on a bundle boundary

 

 

• A source-code column number followed by an offset from the beginning address of a

 

function for rows showing instructions on a bundle boundary
