HP Caliper User's Guide

min_count
Sets the minimum number of functions to be displayed
for all load modules. This is shown as minimum function
entries on reports.
Default value is zero.
Example
If you specify:
$ caliper fprof --detail-cutoff ,80 wordplay
The contents of the Function Details section is a list of functions containing:
• The functions that account for 80 percent of the total IP samples in the wordplay
program.
• Only those functions that each account for more than one percent of total samples
for all load modules. Because percent_cutoff was not specified, HP Caliper
used the default value, 1 percent.
--duration
See “-e or --duration” (p. 65).
--etb-freeze-delay
--etb-freeze-delay integer
Controls the number of cycles of programmable delay for the Integrity servers dual-core
Itanium 2 and Itanium 9300 quad-core processors' execution trace buffer (ETB) from
the point of the rest of the PMU freeze.
Use this option to change the way in which the ETB collects the samples. When you
specify a nonzero value with this option, the ETB will continue to collect instruction
pointer (IP) samples for the specified number of cycles from the point of the rest of the
PMU freeze.
See also “--etb-walkback-cycles” (p. 80).
Example
To produce a flat profile based on execution stalls due to GR/GR or GR/load:
$ caliper cycles -ra -s 100000,5%,BE_EXE_BUBBLE.GRALL
--etb-freeze-delay 12 --etb-walkback-cycles 22
Choosing correct values for the --etb-freeze-delay and
--etb-walkback-cycles options requires knowledge of the Integrity servers
dual-core Itanium 2 or Itanium 9300 quad-core processor pipeline. For information
about the ETB and how it is configured to collect IP values, see Performance Profiling
for Fun and Profit.
