-w

Equivalent to one form of the option for system-wide measurement. The -woption is equivalent to -–scopesystem,attr-mod, which is the default for -–scope system. See “Using --scope system for System-Wide Measurements” (p. 70).

--advice-classes

Used only with the caliper advise command. See “Command Line to Invoke the Advisor” (p. 78).

--advice-cutoff

Used only with the caliper advise command. See “Command Line to Invoke the Advisor” (p. 78).

--advice-details

Used only with the caliper advise command. See “Command Line to Invoke the Advisor” (p. 78).

--analysis-focus

Used only with the caliper advise command. See “Command Line to Invoke the Advisor” (p. 78).

--branch-sampling-spec

--branch-sampling-spec rate

[,variation[,cpu_event[[:threshold=int[:privilege-level-mask=level]]]]

Controls the sampling of the branch trace buffer (BTB)/execution trace buffer (ETB), which produces the statistical call graph. This option is used only with the scgprof measurement.

The default sampling of the BTB is:

branch_sampling_spec

"1000, 5%, BRANCH_EVENT"

The default sampling of the ETB is:

branch_sampling_spec

"1000, 5%, ETB_EVENT"

which means that every 1000 BRANCH_EVENT CPU events (on the Integrity servers Itanium 2) and ETB_EVENT CPU events (on the Integrity servers dual-core Itanium 2 and Itanium 9300 quad-core processors) are sampled, using a 5% variation value.

Use this option to change the default.

rate

Specifies how many sampling events should occur between

 

samples.

 

The default value is 1,000 events.

variation

Specifies how much to vary the number of events between

 

samples. The number or percentage of CPU_counter events

 

that HP Caliper uses to vary the sampling rate. HP Caliper

 

adds or subtracts this number from the interval to vary the

 

sampling frequency.

 

The default value is 5 percent.

cpu_event

Specifies CPU events to measure. The default value is

 

BRANCH_EVENT (or ETB_EVENT on the Integrity servers

 

dual-core Itanium 2 and Itanium 9300 quad-core
