HP Caliper User Guide Release 5.5 (5900-2351, August 2012)

The times cgprof reports are affected by the instrumentation done to collect the data. The times
are inaccurate in absolute terms but valid in relative terms.
HP Caliper accounts for 100 percent of time under main for all applications with 0 (zero)
unattributed samples.
An entry called *ROOT* reflects 100 percent of the time for your executable, which represents the
time from:
• All the functions with no parents
• Out-of-context modules
• Stub code
Call Graph Profile Metrics
Table 11 (page 179) shows the information found in the flat profile part of a Call Graph Profile
report.
In this table, “program object” refers to any of the following:
• Load module
• Function
• Source statement
• Instruction bundle
Table 11 Information in cgprof Measurement Report Fields (Flat Profile)
DescriptionColumn
Percent of the total IP samples attributable to a given program object.% Total IP Samples
Running sum of the percent of total IP samples accounted for by the given program object and
those listed above it.
Cumulat % of Total
Total number of IP samples attributed to the given program object.IP Samples
Number of seconds accounted for by this load module.Secs in Module
Number of seconds accounted for by this function/module alone, if this function/module is
profiled; otherwise blank.
Secs in Func/Module
Number of seconds accounted for by this process.Secs in Proc
Number of times this function was invoked, if this function is profiled. Otherwise, blank.Call Count
Number of milliseconds per function call.Msecs per Call

The column contains one of these:Line |
Slot |
Col,Offset
• A source-code line number for rows showing statements
• An instruction slot number for rows showing instructions not on a bundle boundary
• A source-code column number followed by an offset from the beginning address of a function
for rows showing instructions on a bundle boundary
Column and line numbers are preceded by “~” when they are approximate due to optimization.
The column contains either a source statement, preceded by “>” or a disassembled instruction.
Statements that are out of order due to optimization are preceded by “*>”.
