icache Measurement Report Metrics
Table 27 (page 206) shows the information found in icache reports.
In this table, “program object” refers to any of the following:
•Thread
•Load module
•Function
•Statement
•Cache line
•Instruction
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 |
| 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. |
