Table 14 Information in cgprof Measurement Report: Parent Listings (continued)

Column

Description

Parents

Name of this parent function.

 

 

Cycle

Cycle that this parent is a member of, if any.

*This field is omitted for parents, or children, in the same cycle as the function. If the function, or child, is a member of a cycle, the propagated times and propagation denominator represent the self time and descendant time of the cycle as a whole.

**Static-only parents and children are indicated by a call count of 0.

Column

Description

 

 

% Func Hits In Children

Number of hits due to this child entry and its descendants, expressed as a percentage

 

of the number of hits accounted for by the self entry and its descendants.

 

 

Called*

Number of times the function represented by the self entry was called by this child.

 

 

/Total**

Number of times this child is called by all functions.

 

 

% Call Total

Fraction of Called/Total expressed as a percentage. This represents the percentage of

 

times the self entry called this child entry as compared to the total number of calls for

 

this child entry.

 

 

Children

Name of this child function.

 

 

Cycle

Cycle that this child is a member of, if any.

 

The cycle as a whole is listed with the same fields as a function entry. Beneath it are

 

listed the members of the cycle, and their contributions to the time and call counts of the

 

cycle. Above it are listed the non-member functions that called the different members of

 

this cycle, the number of hits propagated to every one of these callers and the call counts

 

for every one of these callers from outside the cycle.

 

 

*This field is omitted for parents, or children, in the same cycle as the function. If the function, or child, is a member of a cycle, the propagated times and propagation denominator represent the self time and descendant time of the cycle as a whole.

**Static-only parents and children are indicated by a call count of 0.

cpu Measurement Report Description

Available only on HP-UX.

With the cpu measurement, produced by the cpu measurement configuration file, HP Caliper measures and reports per-process or system-wide metrics based on sampled CPU events.

Specify the events and sampling period with the -mevent_set and -speriod options, respectively. You can measure multiple metrics in the same run.

The --cpu-aggregationoption specifies how many low-level samples will be aggregated into one user-reported sample.

The default value used with the cpu measurement is overview. The report shows this information:

•Summary statistics for all of the samples in the measured application:

◦MEAN — Mean value of all samples.

◦STDEV — Standard deviation of the samples.

◦90%CI — 90 percentage confidence interval. This indicates that, statistically, 90% of the time, the mean value will lie within this distance from the present mean value.
