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

• --memory-usage=
Causes process memory usage to be measured at the beginning, at the end, and every 1
second of the process's execution. (This is equivalent to --memory-usage all.)
• --memory-usage=15s
Causes no process memory usage measurement to be taken. Although it does specify a
sampling rate, it does not request that “timed” measurements be made. The system memory
measurement is still taken.
• --mem=e:5:b:t
Causes process memory usage to be measured at the beginning, at the end, and every 5
seconds of the process's execution.
Example Report Output
Memory usage data is only reported in text (-o) and CSV-formatted (--csv-file) reports.
Figure 28 (page 154) shows some example output for an SMP system.

How to Read the Reports
This section explains the information in the System Memory Configuration and Process Memory
Usage tables.
System Memory Configuration Table
This table is always present if the --memory-usage= option is used. It contains a snapshot of
total system memory at the start of the HP Caliper measurement run.
On a ccNUMA system, there are separate entries in the table for each of the logical domains. The
total of all domains is calculated and printed at the bottom of the table.
On an SMP system, there is only one entry for the single, local domain. No total is necessary for
SMP systems.
The fields in each entry are:
Domain Id System identification number of the logical domain. On ccNUMA systems, cell
local memory domains are numbered starting at 1, and the interleaved memory
domain Id is −1. On SMP systems, the only domain is numbered 0.
