runs in user space (user). The privilege levels available are:

•kernel

•all

You can abbreviate this qualifier to PLM. The qualifier is not case-sensitive.

This option overrides the branch_sampling_spec setting in the scgprof measurement.

When you specify the setting by using the command-line option, you can override all or just part of the specification. This allows you to, in effect, create your own default settings.

For example, if the measurement configuration file contains this setting:

branch_sampling_spec = "400000, 10%, BRANCH_EVENT"

and on the command line you specify only variation:

--branch-sampling-spec ,5%

the resulting settings would be a rate of 400000, a variation of 5%, and the CPU event

BRANCH_EVENT.

--bus-speed

[--bus-speed int]

Specifies the bus speed in MHz for the sysbus event set. If you specify the sysbus event set, you must use this option. For example: --bus-speed 200.

--callpath-cutoff

--callpath-cutoffpercent_cutoff[,cum_percent_cutoff[,min_count]]

Specifies cutoff values that limit the hot call paths reported in the Hot Call Paths section of the cstack, scgprof, and cgprofreports.

This option is used in conjunction with the --sort-bymetric option, which you can use to specify the metric to be used for sorting and cutoffs. See “--sort-by” (page 72).

HP Caliper stops reporting information when it reaches a percent cutoff , cumulative percent cutoff, or minimum number of call paths. You have these choices:

•You can limit the report only to call paths that exceed a specified percentage of the total for the sorting/cutoff metric. Once HP Caliper encounters this percentage cutoff, it stops reporting call paths.

•You can limit the report by having HP Caliper stop reporting call paths once the cumulative percent of the call paths so far listed exceeds the cumulative percentage cutoff value.

•You can specify an integer for the minimum number of call paths to be displayed.

This option has these parameters:

percent_cutoff

The percentage of the total for the sort metric that a given call path

 

must exceed to appear on the report.

 

Default value is 1.0.

cum_percent_cutoff

The value of the cumulative percentage at which HP Caliper stops

 

reporting call paths.

 

Default value is 100.

min_count

The minimum number of call paths to be displayed.

 

Default value is 5.
