HP Caliper User's Guide

--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-cutoff percent_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-by metric option, which you
can use to specify the metric to be used for sorting and cutoffs. See “--sort-by” (page 95).
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.
For more information, see Chapter 11 (page 171).
--context-lines
--context-lines all|count_source[,count_disassembly]
For a PMU histogram report, specifies the number of source lines to show before and
after a source line entry with associated performance data.
