HP Caliper 5.3 User Guide (5900-1558, February 2011)

--threads

--threads sum-all|all

Enables per-thread reporting.

Default value is all.,

all Collect and report data per thread.

For a multithreaded program, the Function Summary and the Function Details sections

of reports show information across threads in addition to the per-thread Function

Summary and Function Details sections.

sum-all Collect and report data summed across all threads.

sum-all measures multithreaded applications as one entity. That is, HP Caliper

produces a single report with the results of all threads aggregated together.

This option is supported for these measurements:

• alat

• branch

• cstack

• dcache

• dtlb

• fprof

• icache

• itlb

--traps-reported

--traps-reported trap1[,trap2,...,trap6]

Specifies which traps HP Caliper should report information about when the traps measurement

is run.

You can specify the names of 1 to 6 comma-separated traps. (A trap in this context is a trap,

interrupt, or fault.)

Available on Integrity servers dual-core Itanium 2 and Itanium 9300 quad-core processors only.

If you do not use this option when you run the traps measurement, by default the top 6 traps are

reported.

When the traps measurement is run , information about all 34 traps is collected. The

--traps-reported option only dictates what is reported. You can get a report on different traps

from the same database, using different caliper report runs.

By default, the traps report is sorted on the number of samples in the first trap in the trap list (the

Samples per Trap column in the report). To sort on the total number of trap samples (the Trap

Samples column), use the --sort-by samples option.

For information about all the traps you can specify, see “traps Measurement Report Description ”

(page 214).

--user-regions

--user-regions default|rum-sum

For runs involving the PMU, specifies whether the data should be collected for the entire run

(--user-regions default), or only in regions delimited by the PMU enable/disable instructions

rum and sum.
