% of Cycles lost due to register
dependency stalls (excludes FR/FR
stalls)
Percentage of cycles lost due to register dependency stalls.
It exclude FR/FR dependency stalls.
% of Cycles lost due to GR/GR
dependency stalls
Percentage of cycles lost due to GR/GR dependency stalls.
% of Cycles lost due to FPU
(floating-point unit) stalls
Percentage of cycles lost due to floating-point unit stalls.
% Core cycles due to this thread This indicates the percentage of available processor cycles
that the measured process consumed. The other processor
cycles were consumed by other process(es) running in the
core's other hyperthread or were lost to HyperThreading
overhead.
traps Measurement Metrics
See Table 34 (page 228).
In this table, “program object” refers to any of the following:
• Thread
• Load module
• Function
• Source statement
• Instruction
Table 34 Information in traps Measurement Reports
DescriptionColumn
Percent of the total trap samples attributable to a given program object.% Total Trap Samples
Running sum of the percent of total trap samples accounted for by the given program object
and those listed above it.
Cumulat % of Total
Total number of trap samples attributed to the given program object.Trap Samples
Total number of these traps attributed to the given program object. “Other” is the total number
of all the remaining traps attributed to the given program object.
Samples Per Trap
Kernel Thread ID suffixed with the the name of the routine that the thread will execute once it
is created.

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 “*>”.
